I built a dumb website that calculates exactly how many beers your buddy owes you after helping him move his couch up 4 flights of stairs. It generates an official PDF invoice. You're welcome.

i made this instead of doing anything productive with my life. you fill in what you did for your friend, how long it took, how much you suffered, and it calculates exactly how many beers they owe you. there's a "swear word index" slider. it generates a fake PDF invoice from the "High Commission of Buddy Compensation" so you can send it on whatsapp like an absolute psychopath. the whole thing is vibecoded, the css is obviously AI generated and you can smell it from a mile away, there are emojis literally everywhere because AI. its completely free i make zero money from this, i just mass it for the bit. I regret nothing. https://beer-meter.oraclemarin.fr/

Finally made a little video to show Line Cal in action

Four weeks ago, I released Line Cal - an app that let's users put their calendars on a timeline, with notes and an integrated Kanban task board. I've gotten 40 sign-ups since I launched, am supporting 21 languages, and am continuing to iterate on a consistent basis.

I wanted to share a short demo video of adding an item from the backlog directly onto the timeline to showcase some of what this app can do. Users can use it with or without signing (it uses a local-first architecture, with cloud sync for authenticated users).

Built an iOS app discovery platform focused on surfacing high quality apps from independent developers.

Stamped is a community driven platform built to help people discover incredible iOS apps before they disappear into the noise. https://stampedios.com

Every year, thousands of genuinely useful apps launch and almost nobody sees them. Not because they lack quality, but because visibility on the App Store is heavily dominated by companies with massive budgets, established brands, and existing audiences. The spotlight keeps circulating around the same names while smaller developers get pushed further and further out of view.

That’s exactly why Stamped was created.

Stamped gives independent iOS developers a place to actually be discovered. Every app includes a full creator profile, community based ratings across five categories, demo content so users can see the experience before downloading, and direct access to the builder through platforms like Discord and Telegram.

The goal is simple: connect users with great apps, and connect developers with the people who genuinely care about what they’re building.

The hook: We gamified the iOS app discovery process. Explore apps, verify votes, earn tickets, and compete for monthly prizes.

Explore the sites and tell us what you think

Lately I feel like app stores are great at showing me popular software, but terrible at helping me discover things. 

Rankings and recommendations all seem to push the same names over and over, especially on Android and Windows. If you’re looking for something small, niche, or just different, it feels like you already need to know it exists. 

I’ve started browsing more catalog‑style sites instead of relying purely on store search. One I came across recently is https://unstore.io, which feels more like a directory than an app store: categories, direct downloads, minimal recommendation logic. 

Not saying it’s perfect or a replacement for Google Play / Microsoft Store, but it made me realize how much discovery is shaped by algorithms now. 

Curious how others handle this. Do you mostly rely on store search? Reddit threads? Blogs? GitHub? Random links? 

Would love to hear how you find new or useful apps outside the usual channels.

Why do so many productivity apps fail people who need less friction, not more features?

Productivity tools are powerful in these days. But they just assume a level of discipline and consistency that a lot of people don't have every day. At least I don't have... also there are tons of apps out there, I can't follow the amount of recommendations always ending up in the same place I was at start.

For anyone who's scattered, overwhelmed, or dealing with executive dysfunction, the hard part usually isn't organizing tasks — it's catching things before they disappear. Reducing the mental load. Making follow-through feel less like climbing a wall.

How do you handle that, or am I alone thinking it? (Maybe I'm too lazy).

What actually helps you stay on top of scattered information, half-finished follow-ups, receipts, reminders, things you meant to do last Tuesday? What have you tried that just didn't stick, and why?

The poster your favorite place never had !

Hi everyone,

I’m working on a small side project called AffichAI

The idea is "Every place deserves a beautiful poster"

Not just Paris, New York, or Tokyo but villages, small towns, local landmarks, hometowns, holiday spots, childhood places, or personal travel memories that usually don’t exist in poster shops.

The goal is not to build another generic AI image generator. I’m trying to create a more guided flow for turning a meaningful place into a style poster that could actually be printed and hung.

There are currently two directions:

Create an inspired poster from a place The user enters a city, village, region, monument, or meaningful place. The poster is an artistic interpretation of that place.

Turn your real photo into a poster The user uploads a photo when they want the result to reflect a real landscape, monument, or memory more faithfully.

I’m trying to validate a few things before polishing the product too much:

Would people actually want this as wall art, or is it just visually fun?

Does the “places nobody makes posters about” angle make sense?

Would you rather start from a place name, from a personal photo, or from both?

What usually makes this kind of poster feel too AI-generated: typography, composition, landmarks, smoothness, wrong details, something else?

If printing and delivery were integrated, would that make the product significantly more useful than just downloading an image?

I’d appreciate honest feedback, especially on the positioning, workflow, and poster quality.

If you want to test the idea, comment with a place + 2 or 3 elements you associate with it, and I’ll try generating a few examples.

I built a free skincare routine recommender — would love feedback

Hey everyone,

I built a free web app called Dermia that generates personalized skincare routines based on your skin profile.

You take a quick quiz (skin type, concerns, budget, climate, sensitivity, allergens) and it gives you a full

AM/PM routine with specific product recommendations.

Completely free, no account needed to try it.

Some things it does:

- Matches products to your skin type, concerns, and budget

- Flags ingredient interactions (like retinol + AHA)

- Gives application instructions for each step

- Works for all skin types and concerns

I'm looking for honest feedback:

- Are the product recommendations actually good?

- What's missing that would make you want to use it regularly?

- Anything that annoyed you or felt off?

Try it at dermia.up.railway.app

(Product links are Amazon affiliate links, disclosed on the site. The tool itself is completely free — no paywalls, no account required.)

Built with React + Express + Supabase if anyone's curious about the tech side.

Thanks for checking it out!

I spent months building an AI app for myself — did I waste my time? Be brutal.

Like a lot of people here, I've watched founders sink months into things nobody wanted. So I want to check before I go further.

I was tired of paying for ChatGPT and Claude separately and switching tabs constantly, so I built my own thing — one chat app with OpenAI, Anthropic, Google and xAI in one place. I've used it daily for months and just opened it to the public. It's called Layzer.

Honest question: is "all the models in one app, one subscription" something you'd actually pay for? Or is this a problem only I have, and everyone else is fine keeping them separate

Rather hear it now than after another six months.

I made a subscription tracker that doesn't need your bank login or an account

Most apps in this space want to connect to your bank or at minimum create an account. I didn't want either of those things so I just built one that stores everything locally on your phone.
You add your subscriptions manually, it shows your monthly total, and it reminds you 3 days before anything renews. That's it. No account, no sync, no ads.
Still building it - collecting early interest.
Genuinely looking for feedback on whether the reminder timing is right (3 days before) or if people want more control over that. Would love brutal opinions.

Didn’t want this post to come across as promo-y, so I left the link out. But if anyone wants the tracker/reminder thing I mentioned, I’m happy to share it.

What do you prioritize most when building a web app?

Different developers optimize for completely different things when building web apps:

  • UI/UX
  • Number/depth of features
  • Distribution/traffic
  • Revenue potential (revenue channel)
  • Performance
  • Solving a niche problem

For people who’ve actually shipped products:

  1. What matters most to you?
  2. What turned out to matter way more than expected?
  3. What did you waste time over-optimizing?

Curious to hear real experiences from indie devs and small teams.

spent weeks refining your web app frontend just to leave the staging api completely unauthenticated

most web app deployment checklists stop at whether the bundle size is optimized and the endpoints return a 200, but you are completely wide open if you are not checking how the server handles actual browser-side security constraints. it is incredibly easy to overlook a missing strict-transport-security header, an unconfigured content security policy that allows inline scripts, or exposed backend configurations leaking right through your staging server routes. to catch these silent breaking points before malicious bots start testing for path traversal flaws or cross-site scripting vulnerabilities, offurl.com pushes a domain through 150+ automated security audits across 16 categories in about 30 seconds. instead of drowning you in generic enterprise sales pitches, the report drops the exact nginx, apache, or php configuration code snippets you need to copy and paste to fix the issues on the spot. no account registration and the first premium audit is completely free. run your domain through it real quick so you can verify your infrastructure configuration is actually tight before users find out it isn't

I built Leafmarq — a quiet reading tracker, free PWA, no social feed

Hi r/WebApps. I built a reading tracker over the last couple of weeks and would love some honest eyes on it. It's live at https://leafmarq.com — free, no card.

Why I made it: I wanted a reading tracker that didn't try to be a social network, didn't sell my data, looked decent on a phone, and let me organise books into named lists.

Leafmarq lets you search for a book through Google Books or Open Library, add it to your shelf, and record reading sessions by page or percent with optional notes. A history timeline shows every session you've logged for a given book — click to highlight, edit, or delete.

Honest feedback is welcome.

Built a simple encrypted self-destructing link tool -> would you actually use this? (open source)

I started building \[iKrypt\](https://ikrypt.com) last year and the original idea was something related to smart contracts. The plan was to create a place where users could generate, manage, and interact with contracts and encrypted data through a simple web interface.

After thinking about it more (few months passed and very less traction), I started wondering whether people would actually trust a new website with highly sensitive things like contracts, wallets, or anything important. and honestly who would trust an unkown site with a smart contract? what was I even thinking when I started building this lol.

So instead of pushing that idea, I changed direction and built something smaller. the new site does this- iKrypt now lets you create encrypted self-destructing links for things like:

1/ passwords
2/ API keys
3/ login credentials
4/ .env values
5/ temporary secrets

Current flow is simple:

paste secret -> create link -> send it

The link can expire after a number of views or after a time limit that you set on the site.

No login / No signup required.

I wanted to ask:

1/ Would you use something like this?
2/ Would you trust a new site with temporary secrets?
3/ What would make you trust it more?

Looking for honest feedback before spending more time building it.

I built a webapp that summarises new research papers into scroll-friendly cards every day, did I cook or no?

Link: crux-xi.vercel.app

Every night it gets research papers from arxiv (as much as we can afford to put in LLM), runs them through an LLM, and your morning feed has cards like:

Hook:Self-driving cars can be tricked into hallucinating obstacles that aren't actually on the road
Crux: ..

It's more for satisfying your curiosity and scrolling in a healthy way rather than actually induldging in research but I did find some really interesting research papers as well there.

https://preview.redd.it/hvvyeh5ecv1h1.png?width=643&format=png&auto=webp&s=c27eac14ed4ea44b23f7230bb597a0cbf2b25a87

Also there's a quick search feature which I think is very useful. Select any text on the card and click on the explain button that pops up -> small inline window explains it using Wikipedia/Wiktionary, no tab switching needed.

Still MVP and I would really like to hear your constructive criticism! (edited a typo)

I built a free browser-based chemical structure editor — looking for feedback before the main launch

MolSketch

Hi everyone,I got permission from the mods to post this.

I’m building MolSketch,a free browser-based chemical structure editor,and I’d really appreciate feedback from chemists,chemistry students,and researchers before the main launch.

The tool currently lets you:

  • draw chemical structures directly in the browser
  • use atoms,bonds,rings,charges,reaction arrows,curved arrows,and text
  • customize colors,bond lengths,and display styles
  • copy or download structures as PNG / SVG
  • generate structures from SMILES,compound names,CAS numbers,OCR,and handwritten structure images
  • work without installing desktop software
  • use it on mobile devices

I’m especially looking for feedback on:

  • whether the drawing UI feels understandable
  • what features are missing for real chemistry workflows
  • whether this could be useful for students,reports,slides,or quick structure sketches

This is still early,so I’m not claiming it replaces ChemDraw,Marvin,RDKit,or professional chemistry software. I’m mainly trying to understand what should be improved first.

Demo: MolSketch

Thanks in advance — critical feedback is very welcome.
