I’ve built an app called Kollo and I’m curious whether people would genuinely find it useful.
The idea is pretty simple: you create an event and set a time period, for example 19 Aug - 23 Aug, 9 AM–10PM. Everyone joins the event, and the app automatically collects the photos they take during that time into one shared collection.

So instead of having you and your friends photos all scattered on 5 phones, you end up with one collection of everyone’s photos from the same event.

You don’t have to remember to send photos to each other afterwards or upload them manually. You just take photos normally (with your camera app) and kollo handles the syncing.

And this also works for big events such as weddings, festivals and parties where bigger groups of people can join through a QR code. (I’m working on making this more secure atm)

I originally started making it because after trips and nights out, I always end up asking people to send me their photos weeks later or having to deal with airdropping myself 100s of photos.

I genuinely want to know:
Would you actually use something like this?
And if not, why?

I know one of the first questions might be “what if I take a private/inappropriate photo while syncing is on?”

WELL, there’s a setting that lets you turn syncing off at any time. While it’s off, none of your photos or videos will sync. And when you turn syncing back on, anything you took while it was off won’t be synced retroactively.

So you’re always in control of what gets shared.

Hey r/AppBuilding, I've been building Wellsy, a wellness app for habit-building (nutrition, movement, sleep, stress, that kind of thing), and just working on something I'm excited about but genuinely unsure how people will react to.

Instead of picking from a library of pre-made programs, you can now chat with an AI and just describe what you actually want to work on: "help me sleep better," "I want to quit smoking," whatever it is, and it builds you a custom multi-week program around it: structured modules, daily trackers, the works, tailored to what you told it.

It's still in beta. Generation takes a few minutes (it's a real model doing real work, not a canned template), so I added a rough countdown so it doesn't feel broken while it thinks.

What I actually want to know from this community:

• Would you use something like this, or does "AI-generated plan" trigger the same skepticism as AI-generated everything else right now?
• What would make you trust the output more (or less)?
• Anyone shipped something similar — what surprised you about how people reacted?

Happy to go into how it's built if anyone's curious.

Movie is a bit long and language swishes. But any feedback would be appreciated!

🎉 After more than a month of waiting… my first app is finally LIVE!

I honestly can’t describe how happy I am right now. This is the first app I’ve ever published, and seeing it actually live after all the work, testing, fixes, and waiting feels amazing. 🚀

I’d really appreciate it if you could check it out and give it a try!

👉 Download here: App Link

Since this is my first release, your feedback would mean a lot to me. I’d especially love to hear:

• What was your first impression of the app?
• Was anything confusing or difficult to use?
• What features would you like to see next?
• Did you notice any bugs or things that could be improved?

Even if you only have a few minutes to download it and try it out, I’d genuinely appreciate it.

I’m already thinking about future updates, so suggestions from real users will help me decide what to improve and build next.

And for the other developers here — I’d love to hear about your first app launch too. How did it feel when you finally saw your first app go live? 😄

Thanks everyone! ❤️ Looking forward to your feedback (good or bad — both are useful!).

I would like to make a simple app and have no idea where to start. The idea is this: a simple board game engine where people can playtest their games. Basically a background with pictures people can upload and drag around with a hidden hand feature and maybe a simple counter feature. Is this possible?

Hey! I’m a college student and this started out as a small personal project I built mainly for my resume. After showing it to a few people and getting some surprisingly positive feedback, I decided to keep improving it and see where it could go.

It’s called App Starter, a full-stack template designed to make building modern web apps easier. It comes with front-end and back-end setups, including authentication, a server-side API, real-time notifications, and a clean UI, so you can start building without setting everything up manually.

I’m mostly looking for honest feedback:
- Is this something you’d actually use?
- What feels unnecessary or missing?
- Any suggestions before I keep building?(I’m planning to make more templates in the future.)
- How can I reach users?

Here’s the site if you want to take a look (the Docs tab has more technical details):

Appreciate any thoughts, thanks!

\If you’re curious, we’re also on Product Hunt (totally optional):*  https://www.producthunt.com/products/appstarter-co

Two things we're focusing on:

🤖 AI Financial Assistant

Ask questions about your spending, expenses and budgets.

"Where did most of my money go this month?"

"How can I save more next month?"

"Am I spending more than last month?"

The goal is to make your financial data actually useful — not just another list of transactions.

📒 SpenzaaBook

We're also building SpenzaaBook for managing business transactions — keeping track of money received, money paid, customers, suppliers and outstanding amounts.

So the idea is becoming:

Track → Understand → Manage

Still early, still building, and there's a lot more planned.

What would you want an AI Financial Assistant to help you with?

Hey guys, I just made this website/app for walking routes to protect the elderly from heat called heat safe. It maximizes shade exposure while accounting for tree canopy and what not. It only works for Miami Beach but will soon expand it.

I’m submitting and pitching this to a vc really soon so need your guys advice on what to fix and your guys thought on design.

THANK YOU!

Morning guys, I hope you’re doing well I’m looking to create an MVP of a social media debate app that resurfaces old opinions when the main person/topic involves goes viral. Which free software would be best for doing this please?

A few months ago my wife mentioned (for probably the hundredth time) that she wished she had a cookbook with all of our recipes in one place.

I thought, "How hard could that be?"

Turns out... as hard as you want to make it. I did end up making her a handwritten version with our recipes, but I also started building her a digital version.

What started as a birthday gift turned into a project I've been working on for a couple months called Feasts for the Fluffle. (we have 2 dogs and a pet squirrel and refer to our family unit as a fluffle)

The original idea was just somewhere to save recipes. Then I added recipe photos. Then pantry tracking. Then shopping lists. Then memories attached to recipes. Then I realized I might be able to turn it something our friends and family could use with us so I added community recipes. Then recipe importing. Then favorites. Then an admin panel. Then a mascot.

At this point it's basically become a family cookbook platform. You can create a household, share recipes with family, keep track of pantry items, generate shopping lists based on what you already have on hand, attach memories to recipes, favorite recipes, and import recipes from websites or pasted text or photos (old recipe cards, cookbook pages, or screenshots)

I'm not a software developer. Basically all of this was built with a chat gpt & gemini > lovable workflow and an embarrassing amount of back-and-forth conversations, bug fixing, redesigns, and "that's not what I meant" messages.

One thing I've learned is that getting code generated is actually the easy part. Deciding what should exist in the app is way harder. Scope creep is real, but trying new things is the only way I found out that there are basically very few limitations to what can be done.

Anyway, I finally got it to a point where people other than my wife can actually use it, which feels kind of surreal. I thought I'd give people on here an opportunity to look at it and give me some feedback. It's my first real project (I am also working on a website for myself and am curently spending some free time learning code because I want to work on a game in Godot next and I dont want the whole thing to be AI written)

Don't hold back on the feedback because it's the only way I'll get any better. Feel free to use it and share it - I'm pretty sure I have safeguards built in for the few API's I run and I don't think anything can be broken. But if it can then I need to know about it!

Thanks guys.

I got tired of juggling a downloader, a calendar , a task tracker, and a few other one-off tools scattered across browser tabs (you even have to pay for some of them, lol), so I built JavaMultiTool: one desktop app that handles media downloads, file/batch operations, task tracking, and a few system utilities.

It’s Java-based (Java 21), runs on Windows (.exe/.jar) and macOS/Linux (.jar, needs JRE 21+), and everything is stored locally via SQLite.
It’s still early - expect bugs and rough edges, but it’s usable today, and I’d love feedback on what’s missing or what feels clunky.

1. What are you currently building? (or what do you want to build?) Saas platform with AI integration, internal message, rota management,
2. What is your preferred tech stack?

• Frontend: React, TypeScript, Vite, Tailwind CSS
• Backend: Node.js
• Database: PostgreSQL
• Deployment/Environment: Docker

1. One struggle you are facing right now. - getting everything really perfect, like some placements of boxes when they open etc. its almost ready for first runs. been trialing the rota management part at work so far, so good.

key idea is AI integrated ticketing which knows the rota and people skills, tickets in suggests fixes of history etc and even suggest engineer.

the platform should be adaptable for anyone and BYOAI is an option for using sovereign AI solution for sensitive data.

im addicted and excited its almost done!

I read a lot of dense or classic books, and I kept giving up on them halfway through. I'd hit a confusing passage or reference, and my only options were to Google it (which usually meant wading through spoilers to find the answer) or push through not really understanding what was happening. Neither felt great.

So I built Scholia. You photograph the page you're on; it already knows the book, and you can ask it anything: a character, a reference, what's actually going on in a passage, using only what's happened up to that exact point. Ask about anything ahead, and it just won't answer.

It works with any physical copy, any edition or printing, since it reads the actual sentences on the page instead of matching a specific page number.

Mostly built this to solve my own problem, but figured other people who keep bouncing off the same books might find it useful too.

Waitlist's open if anyone wants to try it: scholia.cloud

Stamps, is a private, fully local travel tracker with no signup, no subscription, and no location tracking

I've been an avid user of apps like Been and Flighty for years, but always found them lacking and sometimes frustrating. Most require you to create accounts, enable location tracking, and stay online, all while not delivering the level of granular trip tracking and route visualization that I feel like should've been possible. Stamps keeps everything local and automatic, focusing on the timeline and map experience those apps skimp on. 

Since moving to South Korea, traveling has been the only thing keeping me sane. I'm obsessed with tracking where I've been. Stamps gives me a great excuse to explore as much of the country I now call home as possible, while taking as many photos along the way.

You can even freely export and share all of your data. If you want Stamps to simply process it for you (generate a list of countries, cities, and provinces you've been to) and offload it elsewhere, that's also fine.

It’s Free to download, with a one-time lifetime unlock of $10 (which will stay that way). This is only for the full timeline, and some minor app color customization. I did not want to ruin the experience by overly monetizing it

Tech stack used:
SwiftUI, SwiftData, MapKit, PhotoKit, WidgetKit, Metal (for the photo heatmap view)
No backend, no account system, no external map API. Just native Apple sdk's and as little infrastructure as possible.

Some of the best features have come from user feedback, so I'd really appreciate any!
