Amazing to see people love what I've built and find it useful enough.!

Never thought that this side project of mine would have an actual use case where people will end up buying the full version.

Initially I had not planned to monetize the product but then the cost of running Google Cloud functions and Firebase was getting difficult to manage so I thought of adding a small charge that unlocks the full version for lifetime. So glad that people found it was worth paying for. 😃

Here is a short description of what I've built and what it does.

I built Chronica because I kept wanting to dig deeper into history

Whenever I learn about an interesting event, I end up asking: What happened before it? What else was happening around the same time? How did we get here? 🔎

That curiosity inspired me to build Chronica - a timeline-based knowledge app where you can start at the Big Bang and move through time, exploring events across billions of years, ancient civilizations, world wars, scientific discoveries, influential people, and much more.

🗺️ You can explore historical timelines, browse an Atlas, discover people and events, and jump between different eras and topics. AND ALL OF THIS COMPLETELY OFFLINE!!

📱Try Chronica on Google Play Store

Looking for a React Native Developer for My Startup App

5 Upvotes

Hey everyone! I’m currently developing a startup app and looking for an experienced React Native developer who can help bring the project to life.
Here’s what I’m looking for:
Timeline: Ideally 3–4 weeks
Technology: React Native
Scope: All app screens/pages completed, with 3 core pages fully functional
Key feature: Compatibility and matching functionality
Goal: A working MVP that I can test with real users and build upon over time.
I’m looking to work directly with one reliable developer rather than a larger agency. Ideally, I want someone who communicates well, offers practical advice, and can help me prioritize the features that matter most for an initial launch.
My goal is to establish a solid foundation without overspending at the startup stage. I’m open to discussing the scope, negotiating a fair price, and adding more features as the app grows.
If you’re interested, please email me at roundsygolf@gmail.com with your experience, portfolio, and estimated pricing. I’d love to connect with someone who can help turn this idea into reality.
Thanks!

NextFlight dev preview: making a cached training record visibly read-only

1 Upvotes

I’m the developer of NextFlight, an iPhone/iPad app in development for FAA flight instructors and their invited students. I’m sharing a specific offline-state design for feedback from other app developers. It is still preparing for App Store release and isn’t available to download yet.

The attached October 8 development screenshot uses synthetic student records. It shows a previously synchronized view with three cues at the top: “Offline · Read only,” the last-sync time, and “Reconnect before making changes. Nothing is queued.” The current public overview also describes reading recently synchronized training records offline.

The distinction matters for a record-based app: being able to read a saved record does not mean it includes the latest changes, and seeing an edit control can suggest that changes will be saved for later. This preview makes the read-only boundary explicit instead of leaving someone to infer it from a disabled button. It is not an offline editing or queued-sync demo.

The tradeoff is screen space. A persistent banner makes that boundary hard to miss, but takes room from the record itself. For apps with shared records, would you keep the timestamp at workspace level like this, repeat it inside each record, or use both? I’m particularly interested in what prevents people from mistaking cached information for a current record after navigating deeper.

The training information is for preparation and record organization. It does not authorize flight, create endorsements or establish checkride eligibility, and NextFlight is not an FAA-approved or in-flight tool.

Hey :)

I've developed an app allowing the user take a selfie and see the photo with different hair styles with ai.

I've sent it to review, they rejected it. I did a remake of the UI (Google play approved it and its available for android), Sent it again and they rejected it again, with a threat to kick me from

the dev programm. How to deal with it? request expedited review? Does someone here has an expirience in this kind of situation?

- Haptic feedback with 4 levels (Off to Strong)
- History up to a full year with notes addable to entries
- Sound effects (On/Off)
- Speech (On/Off)
- Tax calculations (VAT, GST, Sales Tax, etc.)

**Premium unlocks**

- Colour themes (you can even request your own)
- Currency Converter
- Discount Calculator

free Steam price tracker for Android

Post image
0 Upvotes

Hey everyone!

I'm an indie developer, and I'd like to share my Android app, ST Deals: Game Price Tracker.

I built it to make finding Steam discounts and tracking game prices easier.

Main features:

  • Discover new deals, top deals, and big discounts.
  • Track your favorite games and monitor price changes.
  • Browse active Steam sales, including discounted games and DLC.
  • Compare game prices across 44 supported Steam regions.

The app is free and available on Google Play:

https://play.google.com/store/apps/details?id=com.steamdeals.app

I'm still improving it and would really appreciate some honest feedback.

What feature would make a Steam price tracker more useful for you?

Thanks for checking it out!

Quick update on ProdCus

1 Upvotes

I’ve been thinking about whether I should set up a simple email sign-up page where people interested in the app could sign up to get a preview when it’s ready.

My idea is that, instead of building everything on my own assumptions, I could get feedback from people who might actually use the app. What features would be useful? What should I focus on? What’s missing? And most importantly, would people genuinely use something like this?

I’m still early in the process, so I’d rather learn what people actually want before spending too much time building something nobody needs.

I’m curious what you think: Would you sign up to preview an app that’s still in development and share your feedback to help shape it?

Or do you think it’s too early for that, and I should focus on building first?

I’d genuinely appreciate your thoughts.

What if a group chat had a shared wall? I've been building an app around that idea.

3 Upvotes

I've been building an app called nook. and I'm curious to hear what people outside my own circle think about it.

The idea is to make messaging feel a little less like an endless list of messages and a little more like a shared space. Not by replacing chat, but by giving conversations somewhere else to live, too.

Every space in nook. has a selector between Canvas and Chat.

Chat works like you'd expect. You can message, reply, react, share photos and GIFs, send voice notes, draw, see when someone is typing, and check whether your messages have been sent, delivered or read.

The canvas is a shared wall where you can leave things for everyone in the space. You can pin a message from chat onto the wall or create something directly on it. Add stickers, notes, photos, drawings, GIFs and checklists, then move things around and arrange them however you like.

The idea is that not everything has to disappear into chat history. Some things can stay visible, become part of the space, and be revisited later.

I can imagine it being useful for friends planning a trip, couples sharing little moments, or families keeping track of everyday things. But I'm interested in whether other people see the same potential, or whether the canvas is more appealing as an idea than something they'd actually use.

What else is in nook.?

There's quite a bit more to it than the canvas:
Chat: One-to-one conversations and group spaces, with replies, reactions, photos, GIFs, voice notes, drawings, stickers and checklists.

Message interactions: Long-press messages to access additional actions, including pinning messages to the canvas.

Real-time features: Typing indicators, online presence, live message updates, and sent, delivered and read receipts.

Spaces: Create a space, invite people with a code, or start a direct conversation. Users can also connect through their own @handle.

Canvas: A shared, endless wall where you can add, move, resize and arrange notes, photos, stickers, GIFs, drawings and checklists.

Stickers: Around 400 stickers, quick replies and the ability to create your own stickers or turn images into them.

Customisation: Personalise your profile and chat appearance, with colour choices reflected throughout the app.

Dark mode: A complete alternative look, switching from the warm, paper-inspired light theme to a more restrained monochrome aesthetic.

Voice notes and calls: Record voice messages directly in chat or make calls through the in-app interface, with native incoming-call integration.

Media manager: Find shared media without digging through old conversations.

Privacy controls: Manage online and last-seen visibility, notification previews and other account settings.

Temporary conversations: Burner spaces for conversations that aren't meant to last forever.

Offline support: Messages can queue and retry when connectivity drops, with improved recovery when you're back online.

Everything has been built from scratch from the UI and animations to the interaction logic and systems behind each feature. I've spent a lot of time testing, fixing things and working through details that you don't necessarily notice when everything works as it should, especially with real-time features and interactions across the app.

It's been a much bigger project than I initially expected. I've put a lot of work into making sure the features actually work together properly, rather than just making the app look good in screenshots. At this point, I genuinely feel nook. is a solid app, not just an interesting concept or a prototype. Of course, it's not perfect, and there's still plenty to improve. I expect there'll be things I haven't considered until more people start using it, and I'm also thinking about how to make sure it can grow properly as more people join.

The app is built for both iOS and Android. iOS is my primary device, so that's where I've spent more time polishing the experience, but Android is part of the project too.

That's also why I'd like to share nook. with people outside my own circle. I want to hear how other people experience it, what makes sense to them, what doesn't, and what I might be missing. It's easy to get used to your own ideas when you've spent so long working on them, so getting an outside perspective would genuinely help.

nook. is currently in TestFlight, and I'm happy to share access with anyone who wants to give it a try.

Thanks for reading!

Adding a video editor to a react native app (Expo and cli)Adding a video editor to a react native app (Expo and cli)

0 Upvotes

Hi guys
I have been working on a video editor SDK for a while, and recently released a version 0.2.0
The SDK aims to reduce the friction of adding a fully functional video editor into your existing app by a lot.
I did a post on the integration process here

https://nitrakit.dev/blog/react-native-video-editor/
Would appreciate feedbacks on how the DX is, because thats what matters the most to me.

And any thing you might want to do with it in your own app (that may be my SDK does not support yet)

Cheers!
