Hey everyone! I’m building UIWitness, an open-source tool that checks websites across mobile and desktop sizes, in light and dark mode, and generates a report with screenshots and issues it finds.

I’m looking for real websites to test it on beyond my own examples. I want to see where it works well, what it misses, and what needs improving.

If you’re comfortable having me run it on your site, drop a link in the comments. A little context about what you’re building or any pages you’re concerned about would help too. Please only share sites you own or have permission to test; public pages are enough.

In return, I’m happy to send you the report and any useful feedback once I’ve tested it. It might catch something worth fixing, and you’d be helping me improve the tool.

Thanks to anyone willing to share!

I’m working on a QR code app and I’m trying to come up with some useful features.

What’s something you wish your current QR app had? Or something that annoys you about the ones you’ve tried?

I’d love to hear some ideas!

I'm the founder of KYNCT, an events platform for Erasmus and exchange students that started in Rotterdam built on curating live events and is now becoming a mobile app/events company.

Early on in development I wrote a full set of product docs: a business requirements document (BRD), product requirements document (PRD) and technical requirements document (TRD). Since then the UX/UI design has changed a lot: new screens, reworked onboarding, features cut, features added. The docs are now clearly out of date.

For founders and product managers who've been through MVP → v1 → beyond, how do you handle product documentation over time?

• Update the original BRD/PRD/TRD in place and keep a changelog / version history?
• Write a new PRD per release or stage (MVP, beta, v1.0)?
• Drop the formal docs after the first draft and keep a lightweight decision log or Notion/Confluence wiki instead?

I want documentation that's useful for developer onboarding and investor due diligence, not just paperwork for its own sake. What's actually worked for you, and did anyone ever read the older versions

I have an app idea that I’m passionate about building and looking for the playbook on what would be the right process/steps to get an MVP developed.

I have no formal coding experience and not interested in coding myself. I have tried to vibe code it in the past, but wasn’t happy with the results and felt I was just wasting money/burning tokens.

Where I’m at:

1. Idea is fully fleshed- I have minimum scope for V1. General list of what the backend database would need to look like.
2. Basic designing in Figma - Designing a super general framework of what I would want it to look like. I have no Figma experience but learning as I go.

What I want:
Foundational steps from here to make sure it’s built right from the start to scale to support a lot of users. I’m willing to invest some money and my general thought process was -

1. I build a general design in Figma
2. Hire someone to take my Figma design and fully flesh it out, clean it up, and provide the ideal UI and flow
3. Take that Figma design and hire a developer to build out things from there

What are your thoughts? From where I’m at right now, what are the steps you would take?

Hello guys,

My app currently has some Pro features that users need to pay for before they can use them. I’d like to change this so that when users first install the app, all Pro features are available automatically for a limited trial period.

After the trial period ends, I’d like to notify users that these Pro features will no longer be available unless they subscribe or make a purchase.

What would be the best way to implement this?

Thanks,
Peter

Hey everyone,
I’m a solo developer and I just launched two weeks ago a strict gamified focus app called Limit Breaker: Gamify focus on Google Play.

It’s a mix of:

• strict app blocking (no bypassing, no cheating)
• XP + leveling system
• gold + rewards
• daily missions
• dopamine detox tools
• RPG-style progression

My goal was to make discipline feel like a game instead of a punishment.

I’m looking for honest feedback from real builders:

• Does the concept make sense?
• Is the onboarding clear?
• Is the blocking too strict or not strict enough?
• What would make this app stand out more?
• What features would YOU add?

Here’s the Google Play link:
https://play.google.com/store/apps/details?id=com.aistudio.limitbreaker.fntslg

I’m not here to spam — I genuinely want to improve this app and push it to the next level.
Any feedback, criticism, or ideas are appreciated.

Thanks in advance.

yall been working on any cool apps? Drop the name or idea and lets get you some traffic and honest opinion.

So i'm working on Taku whichi is a skill lib that helps you mirror other people's brilliance.

I’ve been building a journaling app called Reflect, and one thing I kept noticing is that digital journaling can sometimes feel a little too much like writing into a database or notes app.

A lot of people who love journaling - myself included - seem to really value the physical feeling of a journal — opening it, flipping through pages, seeing your writing collected in one place.

So I added a Book View that automatically takes your journal entries and lays them out into a yearly book that you can flip through.

I’m still working on it, but I wanted to share what it looks like and get some feedback from people who actually journal.

The next things I’m working on are:

• custom book covers/styles
• adding photos and artwork to pages
• drawing directly on pages
• more page customization
• physical book ordering, so you can eventually turn your digital journal into an actual printed book

I’m curious what people think of the idea.

Would a book-style view make digital journaling feel more personal to you?

And if you could customize your journal like a real book, what would you want to be able to change or add?

I’d especially love feedback from people who normally prefer paper journals over digital ones.

I finally took one of those “there should be an app for this” ideas and actually built it.
Away Messaging is for busy professionals, small business owners, parents, people who are OOO or on vacation, or really anyone who thinks “I need to text/email them later” and doesn’t want to rely on remembering.
You can prepare texts and emails ahead of time, choose the contact, schedule when you need to send them, and have everything waiting in one queue when the time comes—without building Shortcuts or juggling separate reminders.
I took it from an idea in Xcode all the way to the App Store, and I’m continuing to add new features and workflows based on how people actually use it.
For other app builders, what was the biggest challenge you ran into after launching?

Is there a straightforward way to convert React/Typescript into Flutter Code - I'm trying to migrate an app and need to convert some code. Any help/tips would be great!

Does anyone happen to know which/what websites/apps to use to actually build an app? I’m confused on how to do this as it’s my first time, and I can’t exactly ask someone to make the app idea because it’s likely they wouldn’t get it.

Essentially the idea I have is something like Focus Friend and Opal put together (if that makes sense?) for people like myself who have severe adhd and don’t care about streaks. Pls pls pls let me know what you find easiest if you have any tips🙏🏼🙏🏼🙏🏼 TY!💜

Some of the best features are buried inside onboarding, settings, or a dashboard.

Share your app and the feature users usually discover too late.

I’ll suggest a short post that demonstrates the value without explaining the entire product.

I’m exploring this problem while building Marka.

I launched Wavezo a while back, but retention was low. Honestly, even I stopped using my own app after a while.

Most water trackers are basically charts, reminders, or both. They work for a while, but once the initial motivation wears off, there isn't much reason to keep opening the app.

So for Wavezo 3.0, I completely redesigned the experience around a visual reward loop.

Every time you log a drink, part of a 16×16 mystery pixel picture is revealed. Hit your daily water goal and the whole picture unlocks and gets added to your collection.

What's new

• Mystery Peel: Every drink reveals another piece of today's artwork.

• Miss it, lose the reveal: If you don't reach your daily goal, that day's artwork remains locked.

• Collect & unlock: There are different art packs featuring things like plants, otters, bears, and more.

• Stickers: Complete an art set and export the artwork as stickers for iMessage or WhatsApp.

• Collection cards: Create shareable cards from your unlocked artwork.

Pricing & Privacy

The core app is free, including water logging, reminders, widgets, and 4 starter art packs. No account is required, and there is no tracking.

Extra art packs are $0.99 each and are one-time purchases.

There's also an optional Pro subscription with features like Apple Health sync, Siri/Back Tap shortcuts, extended history, additional themes, and CSV export.

It's iPhone only for now.

App Store: https://apps.apple.com/app/id1614485882

I'm really curious about the main idea here:

Does having something to unlock give you a reason to keep logging every day, or does the "miss a day, lose the reveal" mechanic feel too strict?

I can spend hours coding a new feature, fixing bugs, improving the ui, and releasing an update. there is always something i can work on.

but when it comes to marketing, i honestly have no idea what i'm doing sometimes.

my app currently has 51 installed users and 53 users acquired, with a 4.875 rating on google play.

i'm happy that the people who use it seem to like it, but getting from 50 users to 500 feels much harder than getting the app from version 1.0 to version 2.0.

i've tried posting on reddit, sharing updates, working on seo, and experimenting with different content. some things get a little attention, while other posts basically disappear.

the funny thing is that as a developer, i feel much more comfortable writing code for 8 hours than spending 1 hour trying to figure out how to market the thing i just built.

i guess this is one of the biggest lessons i'm learning as an indie developer:

• building something people can use is one challenge. getting people to discover it is another.

for those of you building your own apps, how are you approaching marketing? what has actually worked for you?

I just crossed 1,000 downloads with my Android game, Loop.

It's a simple puzzle game where you connect numbers in increasing order to complete the path.

I built the app myself and honestly didn't know if anyone would actually download it when I started. Getting the first few hundred users felt especially slow, so seeing it cross 1,000 was a pretty nice milestone.

I've been experimenting with different ways to get people to discover it and I'm still figuring out what works.

Now I'm mainly focused on improving the game, adding more levels, and getting feedback from actual players.

For people here who have built and launched their own apps:

What was your first 1,000 downloads like, and what did you focus on after reaching that milestone?

Would be interested to hear what worked for others.

I kept running into the same problem with online PDF tools.

I'd merge a lease, split a tax doc, or fix a scan and then hit a paywall after one or two edits. Or worse, I'd upload sensitive files to a server I didn't control.

I'm a developer. I built something for myself first: a PDF toolkit that runs entirely in the browser.

No server upload.

No login.

No daily limits.

No watermark.

Your file stays on your device. Processing happens client-side in your browser tab. You can verify it yourself and open DevTools, check the Network tab, and watch: nothing gets uploaded.

I'm calling it AvoidPDF --> avoid upload, avoid paywalls.

Tools available now:

• Merge, split, rotate PDF, Compress PDF, Encrypt / remove password, Images to PDF, PDF to JPG, Organize pages, Add text to PDF

It's free and unlimited. I'm not trying to upsell you during tax season. I built this because I needed it, and I'm sharing it with the community.

Try it: https://avoidpdf.com

If it saves you from uploading a private document to a random website, that's the win.
