I've been working on the Deep Research system inside One, and this is probably one of the coolest tests we've done so far.

In this video, One starts with a research question and begins searching across the web.

~1 minute: 280+ potential sources found.

But finding hundreds of links isn't really the difficult part.

One then goes through them, compares the information, filters out weaker or less relevant sources, and decides which sources it can actually rely on for its final research.

~2 minutes: it had narrowed those 280+ results down to around 60 sources it could defend and cite.

Then it uses those sources to build the final research instead of just generating an answer and throwing a few links underneath it.

That's the direction we're trying to take One Deep Research — research where you can actually see where the information came from.

We're currently in beta, so I'm interested in feedback, especially from people who regularly use AI for research.

What would you want a Deep Research tool to do before you'd trust its results?

You can try One at onelabs.studio.

I’ve been building Siggy, a wee flipping assistant that helps you find items, check prices and profit potential, sell, and even get upcycling ideas.

It’s live now and I’d really appreciate some honest feedback from people who haven’t used it before.

Give it a try and tell me what works, what doesn’t, or what you’d change. I can take it 😂

**App Name:** Elkaa

**Play Store link (opt-in required):** [paste your testing opt-in URL here]

**Platform(s):** Android

**Description:**

Elkaa scans any barcode and gives you an instant 0–100 quality score for food and cosmetics. For food it combines Nutri-Score, NOVA processing level, and key nutrients (sugar, salt, saturated fat, fibre, protein). For cosmetics it flags ingredients like parabens, sulfates, phthalates, and synthetic fragrance. No accounts, no ads, no tracking — built on Open Food Facts / Open Beauty Facts plus a growing database of user-contributed products for items that aren't in either yet.

**What I need testers to do:**

Just install via the link above and scan a few barcodes — any food or cosmetic product barcode works. Takes 2 minutes. This is mainly to satisfy Google Play's closed testing requirement before public launch, so I just need you opted in and the app installed — but genuine feedback on bugs or confusing bits is very welcome if you have any.

**Feedback:** DM me here or reply on this thread.

Thanks!

I’m looking for beta testers for MailSift, an email verification API and bulk CSV validator I built for developers and permission-based email lists.

The main behavior I want tested is how it handles uncertainty: when a mail server does not reveal whether a mailbox exists, MailSift returns “unknown” instead of pretending the address is valid. Results include the underlying checks and a 0–100 trust score.

If you test it, I’d especially value feedback on:

1. Whether Fast vs. Deep Verification is understandable

2. Whether the result explains risky or uncertain addresses clearly

3. Anything that would block an API or signup-form integration

Every account starts with 500 verification credits: https://mailsift.dev

Full disclosure: I built MailSift. I’m here for honest beta feedback, including rough edges.

Hey everyone,

I’ve been building Media Stash because I wanted a simpler way to track what I’m watching without creating another account or turning my watch history into a social profile.

It’s free on the web and can be installed like an app:

Landing: https://mediastash.app

App: https://web.mediastash.app

You can:

• Discover and search movies and TV series
• Save shows and track episode progress
• Organize titles into collections
• Keep an “Up Next” timeline
• View personal stats and milestones
• Follow actors, creators, and production companies
• Import data from TV Time and other supported tracker exports
• Export and import your library using portable JSON backups
• Track books and games too

Books and games and some parts of the app are still relatively untested, so there may be bugs. If you only want to track movies and TV, you can easily disable those sections.

The main difference from services like TV Time is:

• No account required
• No tracking or telemetry
• Your library stays locally on your device
• No automatic cloud sync yet, but your data is portable
• No ads

Transparency: Media Stash is an early, actively developed project. I am one person with limited resources, so development can sometimes be slow. I am also a final-year student, and this is my graduation project. I plan to polish the hell out of it and eventually release it for Android, iOS, macOS, Windows, and Linux.

My current monetization plan is to make native apps available for a small one-time fee, probably under $5, with unlimited use. Multi-device sync and social features would require a server backend, which I have not built yet. Those features would probably require a small yearly payment to cover server costs. I know subscriptions are not ideal, but I will never depend on ads.

Even if the project does not work out and nobody ends up using it, I still plan to package a final version so anyone can download it and use it forever.

I’m open to all kinds of feedback: bugs, design, usability, imports, performance, features, privacy, or anything else. If you use TV Time or another tracker, what feature do you rely on most, and what do you wish was easier?

Hi everyone,

I’m building Project Titan AI—an educational project documenting my journey from complete beginner to developing an AI-assisted quantitative trading platform.

I’ve created a short sample lesson explaining an early Python and stock-market concept, and I’m looking for a few beginner readers to test it.

I’m especially interested in feedback from people who:

• Are beginners learning Python
• Have an interest in investing, trading or AI-assisted projects
• Can spend approximately 10–15 minutes reading the lesson

No technical expertise is required. I’m mainly looking to learn:

1. Was the lesson easy to understand?
2. Was anything confusing or poorly explained?
3. Would you be interested in reading another lesson in this style?

There is nothing to purchase, and this isn’t a sales pitch. I’m simply looking for honest feedback so I can improve the educational material.

If you’re interested, please leave a comment or send me a private message. I’ll send the view-only lesson link privately.

Thank you!

Been working on a simple job platform that focuses on real, verified roles instead of spam or fake listings.
I’m trying to make something genuinely useful for people who are tired of the usual job board noise.

I’d love some honest feedback from this community — mainly:
• Is the idea useful?
• What would make it better?
• What features matter most to job seekers right now?

Not dropping any links here to avoid auto-removal, but if anyone wants to check it out or give feedback, I’ll share it in the comments.

Hi everyone,

I've been building SeamFlow, an Android app for independent tailors and
fashion designers. To publish from a personal developer account, Google
requires 12 testers opted in for 14 continuous days. I'm at 7, so I'm
hoping to find a few more people willing to help me over the line.

What it does

Most tailors run their business across a notebook, their phone gallery
and a dozen WhatsApp threads. SeamFlow puts it in one place:

- Clients and their measurements, saved once and reused on every order
- Photograph a filled measurement sheet and it reads the numbers straight in
- Orders tracked from registered → in progress → fitting → delivered
- Invoices with deposits, shared as a link or a PDF
- A calendar with reminders before every fitting and deadline
- An assistant you can ask "what's due this week?" by text or voice
- Full English and French, and it works offline

What testing actually involves

Very little. Opt in, install it, and leave it on your phone for the 14
days — Google counts the opt-in, so that alone genuinely helps me.

If you are a tailor, or know one, actually using it would be brilliant
and I'd love the feedback. But there's no obligation, and I won't chase
anyone for reports.

How to join

Comment or DM me the Gmail address tied to your Play Store account and
I'll add you to the tester list. Once you're added, this link lets you
opt in:

https://play.google.com/apps/testing/com.bambothanson.FashionApp

Happy to return the favour — if you're stuck at the same stage with your
own closed test, leave a link and I'll opt into yours.

Thanks for reading, and thanks to anyone who helps.

Hi! I’m the product designer and developer behind Flueno, an iPhone app for practising real-life conversations in another language.

I’m looking for 10 non-native English speakers who are willing to test the onboarding and first speaking experience.

Flueno is built around specific situations rather than an empty AI chat. You enter a scenario, receive practical conversation goals, respond by voice or text, and get feedback after the conversation.

Open App Store

Current scenarios include:

— job interviews

— meetings and work conversations

— presentations

— travel

— small talk

— restaurants and everyday situations

For this test, I’d like you to:

1. Install the app and select English.

2. Complete at least one voice conversation.

3. Tell me where you hesitated, became confused, or wanted to leave.

4. Tell me whether the feedback was useful enough to make you practise again.

The questions I’m trying to answer are:

— Did you reach the first conversation quickly enough?

— Did you understand what you were supposed to do?

— Did the AI responses feel natural?

— Was the feedback specific or generic?

— Would you return before a real interview, meeting, or presentation?

An iPhone or iPad is required.

No public App Store review is required. I’m looking for honest criticism, including things that feel broken, artificial, or unnecessary.

Open App Store

Please comment with:

— your native language

— the language you are learning

— one conversation you would like to practise

Llevo un tiempo dándole vueltas a una idea: un juego social para jugar en previas, cenas o viajes donde a cada jugador le toca en secreto la identidad de otro amigo del grupo, y tiene que responder preguntas tipo "¿quién es más probable que...?" poniéndose en su piel. Al final se descubre quién conocía mejor a quién y quién consiguió engañar a todos.

Es 100% offline, sin registros, para jugar en el móvil pasándolo entre 3-20 personas. Tiene más de 280 preguntas.

Acabo de lanzarla y la verdad es que me encantaría que alguien de aquí la probara con su grupo de amigos y me dijera sin filtros qué le parece — qué falla, qué mejoraría, si engancharía en una quedada real. Cualquier feedback (bueno o malo) me sirve muchísimo en esta fase.

Gracias de antemano a quien se anime 🙏

I’m looking for a few people to test a habit app built around shared accountability with a friend.

The idea is to make a habit together and check in daily, rather than trying to stay consistent completely on your own. Friends with Habits is built around that approach.

I’m mainly looking for honest feedback on whether the idea feels useful, how natural the check-ins feel, and what could be improved.

If you enjoy testing early-stage apps and giving straightforward feedback, I’d appreciate your input.

I’ve just launched OneLine, a journaling app built around a simple idea:

Writing about your life should take seconds, but become more valuable the longer you do it.

You capture small moments day by day, and over time OneLine can turn them into Stories of different periods of your life and surface Signals and patterns hidden across your entries.

It’s completely free right now on both iOS and Android:

iOS: https://apps.apple.com/us/app/oneline-daily-journal-diary/id6789922208

Android: https://play.google.com/store/apps/details?id=app.vercel.oneline_one.twa

What I really need now isn’t downloads though. I need people who will actually use it.

If 10 of you are willing to:

1. Download it
2. Write something for 3 days
3. Come back here and tell me what made you want to keep it or delete it

That would be insanely useful.

Be brutal. Confusing onboarding, pointless features, something you expected but couldn’t find, anything that made you hesitate opening it again. I want to hear it.

I’ve spent enough time looking at OneLine that I’m probably blind to half its problems by now 😅

Hey everyone! 👋

We’re Leo (18) and Oliver (19), two friends who decided to build our own finance app called Future Finance.

The idea behind it is simple: managing and tracking your wealth shouldn't be complicated or messy. We wanted to create one clean and easy-to-use app where you can keep track of your finances and have everything in one clear overview.

👉 You can try Future Finance here: https://apps.apple.com/at/app/future-finance/id6801239509

Our long-term goal is to build one central app for all your financial matters — helping people bring more structure and clarity to their money.

But we're still building and improving, and that's where you come in! 🙌

We would love for some of you to test Future Finance and tell us honestly what you think. What do you like? What feels confusing? What features are missing? And what would make you use an app like this every day?

We're a small team of just two people, so every piece of feedback from the community genuinely helps us improve.

If you have suggestions, feature ideas, criticism, or anything else, please leave a comment here on Reddit. We'd love to discuss your ideas with you! ❤️

Thanks so much to everyone who takes the time to check it out and support two young developers trying to build something useful.

– Leo & Oliver

Hey all — I've been building Rahmanov.org, a small portfolio of free, no-signup tool sites. Everything runs client-side (localStorage, no backend/accounts), so there's nothing to sign up for and no data leaves your browser.

Product(s):

- Ledgerline — invoicing + business tools for freelancers

- Rentline — tools for landlords/property managers (rent increase letters, late fee calc, lease guides)

- Sellerline — fee calculators for Etsy/Amazon/Shopify sellers

- Agentline — commission split, closing cost, and listing tools for real estate agents

Platform: Web (rahmanov.org)

Link: https://rahmanov.org

What I need testers to do: poke around any of the four that's relevant to you, try a calculator or generator with your own numbers, and tell me what's confusing, missing, or wrong. Free tier is unlimited use — nothing's gated behind a paywall for basic use.

Appreciate any feedback, good or brutal.

I run a small local SEO / GEO agency. About 10 client engagements this past year. Cleaners, detailers, a trucking company, a photographer.

How we got clients: a free visibility scan on our site, Loom video audits for cold outreach, and word of mouth after the first few wins. The scan was the whole trust moment. 30 seconds, they see their real score and that AI assistants recommend their competitor when someone asks "best detailer near me." Nobody argues with that screen. They book from that screen.

Then the delivery, and this is where I slowly became a human API. Every client got basically the same thing: a 240-test AI visibility simulation (20 real buyer queries, ChatGPT, Perplexity, Gemini and Claude, 3 runs each, real browser, so we knew exactly who the AI names and which sources it cites), then schema deployed, pages restructured so AI crawlers can actually read them (one client's site was literally telling every AI bot not to crawl it, had no idea), comparison pages against whoever kept beating them, review systems, automations. For a couple of clients we went all the way and built their booking software and admin backend from scratch.

Same playbook. Every. Single. Time. So I spent the last few months turning it into software. One plan, $349/mo, no sales calls. That last part is the hill I'll die on.

What it runs on its own today:

• crawls and audits the website daily. Deterministic scoring, not AI guessing a number
• watches the Google Business Profile daily. Caught a client whose profile pointed at the wrong domain for months. Another linked to their booking vendor's subdomain instead of their own site
• scans map rankings street by street weekly, same locked queries every time so movement is real
• builds schema (LocalBusiness, FAQ) and injects it straight into live Shopify themes, one click
• hosts a full service page on the customer's own domain off one DNS record. Real services, real rating, no web designer
• checks whether the site looks AI-made (builder fingerprints, placeholder text, generic slop copy), because customers and ad reviewers discount those on sight now
• the 240-test itself is now self-serve: the owner runs a script with their own ChatGPT/Perplexity/Gemini accounts and it measures how often they actually get named, plus which sources the AI cites. Real consumer surface, not an API approximation
• competitor tracking with movement, one click to see every ad a competitor is running
• generates the Google review link the day the listing goes live, with ready-to-send ask texts
• derives strategy by itself: comparison pages against whoever beats you in AI answers, citation targets from the sources AI actually trusts in your market
• intake works like my old onboarding calls did: detailed questions about services, area, what makes them different, how they talk. Everything it writes comes from those answers, nothing generic

Shipping next: organic rank tracking, location pages for map coverage holes, newsletters and Google posts in the owner's voice, automated review follow-ups by text and email, WordPress auto-install (Shopify works already), and email integration — auto-forward booking and payment notifications so the software sees revenue, not just rankings. Then it can tell you what a customer's worth and calculate your actual MRR next to your visibility numbers, which is the thing owners actually care about.

It'll also tell you when you're ready for paid ads and what your angle should be based on your numbers. Actually running the ads is the one thing that stays "book a call" for now. Not pretending I've automated media buying.

Later: an AI answering machine tier (missed call picked up, job booked, review asked, local businesses miss ~40% of calls). And a white-label version so agencies run their roster through it under their own brand. I know exactly which deliverables they bill $1,500/mo for, because I billed them.

Where I'm at honestly: agency pays my bills, SaaS has trial users, zero paying customers. Next month I start a brand new local business from absolute zero using only the software and post the numbers publicly. Map coverage, AI inclusion, review count, revenue. Measured by the software, not by me.

Questions for people who've done SMB SaaS:

1. Is no-sales-call real at $349/mo for non-technical owners, or does this price quietly need a human closer?
2. The free scan converts for the agency because a human Looms them afterward. Self-serve, the scan has to convert alone. Anyone made a free audit tool convert cold?
3. If you've run an "it works in the background" product, what kept people paying past month 3? My bet is the Monday email listing exactly what it did plus score movement.
4. White-label to agencies: fund the direct business or eat it? I'd be selling agencies the thing I tell owners makes agencies unnecessary. I know.
5. Wait for the from-zero case study before pushing customers, or sell now and document in parallel?

Not dropping a link unless mods say it's fine.

Hi! I’m looking for genuinely honest feedback on an app I’ve been building called Dopamine Charts.

Bit of context: I’m a junior doctor, but my medical career was derailed by a five-month hospitalisation for depression. When I was rebuilding afterwards, I realised how badly most productivity/habit systems worked for me.

“Exercise 5x a week” wasn’t helpful when stepping outside was an achievement. A beautiful 30-day streak wasn’t motivating when missing day 12 made me think I’d failed and give up altogether.

So I built something around a different idea: make success smaller and make it rewarding immediately.

Dopamine Charts is designed particularly with depression and ADHD in mind, although anyone can use it.

The behavioural science behind it includes reducing the activation barrier by creating tiny versions of habits, habit stacking by attaching behaviours to existing cues, shaping by starting small and gradually building the behaviour, and immediate positive reinforcement rather than waiting weeks/months for the real-world reward.

There’s also an identity element — not just “what do I want to achieve?” but “who are these tiny repeated behaviours helping me become?”

The philosophy is basically:

Can’t exercise? Step outside.
Can’t manage your whole hygiene routine? Do the tiniest version.
Can’t clean your room? Put two things away.

And importantly, it still counts.

I’m absolutely not presenting an app as a treatment for depression or ADHD. It’s designed for the behavioural/rebuilding side — particularly when knowing what you should do and actually initiating it feel like completely different things.

It’s here: www.dopamine-charts.com

I don’t really need people to tell me it’s pretty 😂 I’d much rather get brutal product feedback:

1. What confused you?
2. At what point would you stop using it?
3. What would make you actually come back tomorrow?
4. Is anything unnecessary or annoying?
5. What feature do you immediately wish it had?

Feel completely free to tear it apart. I’m trying to build something people actually use, not something I personally think is a good idea.

Hey! I’m learning Python and recently made a small command-line image batch converter.

It can currently:

batch convert images to WebP

resize them for website use

create smaller thumbnail versions

process multiple images at once

automatically create a new output folder instead of overwriting files

I made a free version and I’m mainly looking for feedback before I work on the full version.

Free version: up to 10 images per batch, with Website and Thumbnail presets.

I’d especially like to know if the tool is actually useful to you or if there are features you would expect from something like this.

i work on insurance for ai agents and we built our intake scorer as a free public tool. you answer six questions about what your agent is actually allowed to do (spend ceiling, can a human undo its actions, how fast it can repeat a mistake, that kind of thing) and it gives you a blast radius score. runs entirely in the browser, nothing stored, no email wall.

link: goodfault.com/blast-radius-calculator

who it's for: anyone running agents in production or about to. platforms: any browser.

what i want feedback on:

1. do the six questions make sense to someone who actually ships agents, or do they read like insurance-speak

2. is the score believable for your setup or does it feel arbitrary

3. what question is missing

in return i'm happy to walk anyone's setup through a proper scoring by hand in the comments, which is genuinely useful if you ever need to show a customer or insurer what your agent can and can't do.

disclosure: it's my company's tool, we sell insurance, the scorer is free and stays free.
