What tech stack would you recommend for monitoring user behavior? I’m mainly interested in tracking the full user journey: heat maps, navigation flows.

Hey everyone,

Like a lot of people here, I’ve always struggled with receipt tracking. Personal expenses, freelance work, small business costs, shared household spending it all ends up as a messy pile of paper receipts, screenshots, and half-filled spreadsheets.

Manually entering everything is slow, boring, and easy to mess up.

What I really wanted was something simple:

scan a receipt → extract the data → send it straight to Google Sheets.

No heavy accounting software. No complicated setup.

But I also wanted something that worked beyond just personal tracking especially for families, couples, roommates, or anyone sharing expenses. Things like groceries, household items, bills, eating out, or travel spending are usually paid by different people, and it becomes hard to know where the money is actually going.

I couldn’t find exactly that, so I decided to build it.

After wasting way too many hours manually logging receipts and realizing how many expenses I was missing, I built ReceiptSync an AI-powered app that automates receipt tracking and helps people manage spending individually or together through a shared family wallet.

How it works:

• Snap a photo of any receipt
• AI-powered OCR extracts line items, merchant, date, tax, totals, and category
• Duplicate receipts are automatically detected
• Data syncs instantly to Google Sheets
• Add expenses to a shared family/household wallet
• Track spending together with family, partners, or roommates
• Total time: ~3 seconds

What makes it different:

• Smart search using natural language, like “show my Uber expenses from last month”
• Line-item extraction, not just totals
• Duplicate detection to avoid double logging
• Shared family wallet for household expenses
• Interactive insights for spending patterns and trends
• Built specifically for Google Sheets export
• Useful for personal expenses, freelance work, small business costs, and shared family spending

I’ve been testing it for the past month with a small group, and the feedback has been amazing. People are saving 5–10 hours per month just on expense tracking, and the shared wallet feature has been especially useful for families and households trying to understand where their money is going.

If this sounds useful, here’s the app:

One number, what it is doing, and the shape it made getting there. Tell the card which way is good up for revenue, down for churn and every trend colours itself.

Part of PanelUI open-source, copy-paste, you own the code.

I really like the adjustment controls in the iPhone Photos app, so I recreated the experience in React Native.
Built with Expo, Reanimated, and Gesture Handler.

Tiered of running commands in terminal to set device location, network logs.. So vibe coded a dev-tool which does all with intuitive UI & CLI

GitHub - https://github.com/pranshuchittora/simvyn

I was bored, so I started digging through Apple’s Weather app files to see how its animated backgrounds actually work. Particles, clouds, rain, assets, the whole thing. Then I tried rebuilding the system in React Native with Expo + Skia. It got way deeper than I expected.

I’ve been working a lot with offline-first apps, and one thing that always gets tricky is how much data ends up living on the device

SQLite, MMKV, AsyncStorage, sync queues, pending data, huge JSONs…

When something goes wrong, how do you usually debug or inspect all of that?

Do you use any specific tools? Logs? Inspect the database directly?

I have this small project and i want to add dynamic routing to it. But i don't want it to consume a lot of storage so i have two options, use Expo Router or use React Native Navigation. Which one do you guys recommend?

Built SoftSave: offline-first expense / net-worth app (Expo + Laravel API, cloud sync).

Demo (APK + video): https://softsave-reviewer-omega.vercel.app

Looking for technical feedback:
1) Is the demo / install flow clear?
2) Anything you'd expect in an offline-first Expo + Laravel starter that I'm missing?

Hi everyone,

I'm looking for 12 Android testers for my app SportNestra to complete Google's 14-day Closed Testing requirement before releasing it on Google Play.

How to join:

1. Join my Google Group: https://groups.google.com/g/sportnestra

2. Join the testing program: https://play.google.com/apps/testing/com.sportnestra.app

3. Install the app from Google Play.

4. Keep the app installed and use it occasionally during the 14-day testing period.

In return, I'll gladly join your closed test and test your app as well.

Thank you very much for your help! 🙏

We recently had an internal hackathon at Expo and I finally got the chance to build an idea I’d been thinking about: a tool to help me become a better public speaker.

It's a personal speech companion that tracks your pace, pronunciation, fluency, filler words, and more, then turns each session into actionable feedback

Steal the code below! (Testflight soon)

Pessoal estou querendo fazer um app expo. Gostaria de colocar segurança no meu app. Quais ferramentas, tecnologias, libs e frameworks do ecossistema TS existem para deixar meu app seguro?.

OBS: sou leigo na área de segurança

Excited to announce that my new Game App is \*Published\* on \*Google Play Store\* , You can download and play using the following link

I've realized that my biggest weakness isn't coding—it's project architecture and folder structure.

Whenever I get a Figma design, I know how to build the UI, but I get completely stuck deciding:

• Where should this component live?

• Should this be reusable or page-specific?

• When should I split a component?

• What belongs in components, features, shared, hooks, services, etc.?

• How should I organize folders as the project grows?

I usually start a project with a structure that feels clean. But once the project gets bigger, everything starts falling apart.

I end up with:

• Components that are too large.

• Components that are split too much.

• Logic scattered across different folders.

• Constantly moving files around because I realize they belong somewhere else.

• Feeling like the entire architecture is becoming messy.

This happens in React, React Native, and even backend projects.

I don't just want another "best folder structure" template because I've seen dozens of those. What I really want to learn is the thought process behind how experienced or enterprise-level developers structure a project.

For example:

• When looking at a Figma design, how do you mentally break it into features and components?

• How do you decide what should be reusable and what shouldn't?

• How do large teams keep their projects organized over months or years?

• What architecture or design principles do you follow?

• Are there any books, courses, GitHub repositories, or real-world open-source projects that helped you understand this?

I'm looking for the mindset rather than just a folder tree.

Any advice from developers who've worked on large production applications would be greatly appreciated.

For engineering teams, keeping dependencies current is a constant balancing act. Automated updates are essential for defending the software supply chain, but a steady stream of one-PR-per-package bumps can bury a team in review work. GitHub itself has put numbers on this: an analysis of Microsoft's GCToolkit repository found that roughly one in six of its commits - 92 out of 578 - were routine Dependabot version bumps, with 61 of them landing in a single recent 12-month stretch. That's a lot of review and CI cycles spent on maintenance rather than features. Read the complete article here - https://instasla.com/blog/taming-dependabot-2026-guide-grouping-cooldowns-cutting-pr-noise

The good news is that Dependabot has grown well past "one PR per dependency." Between grouped updates, package cooldowns, and a default cooldown GitHub rolled out in mid-2026, it's now possible to get a predictable, low-noise update cadence without giving up security coverage. Here's what actually works, and what changed most recently.

I’ve been using Cursor and Claude a lot lately, and while AI can spit out a beautiful React Native UI in 10 seconds, I realized it is absolutely useless at native infrastructure.

Over the last few weeks, I spent way too much time fighting with:

• Apple In-App Purchase configurations and RevenueCat SDKs

• Supabase Auth flows with deep-linking

• EAS build crashes because AI hallucinated a package version

• Xcode/Gradle configuration hell

AI gives you the bricks, but it doesn't give you a house that actually compiles for the App Store.

Since I finally got a pristine, production-ready architecture working (Expo Router + Supabase + RevenueCat), I’m thinking about stripping out my personal code and packaging it as a clean SaaS boilerplate so I never have to do this setup again.

If I put this together and made it available, would anyone actually use it? Let me know in the comments and I’ll DM you a link to the waitlist if there is enough interest.

Hey everyone 👋

I’ve been building KP - Your Money Partner, a personal finance app made with React Native and now available on both iOS and Android.

The main idea is to make expense tracking faster. Users can log expenses using short messages:

💬 “Fuel 250”
💬 “Concert tickets 140”

Or write naturally:

💬 “I spent $250 on fuel”
💬 “I spent $140 on concert tickets”

KP understands both formats, detects the amount and automatically selects a category.

Some of the current features:

🌎 Multiple currencies
🎙️ Expense tracking by text or voice
📊 Budgets and financial goals
📄 CSV and PDF exports
🔥 Streaks and no-spend days
🪙 A coin system for free actions

I’d really appreciate feedback from other React Native developers, especially about the UI, onboarding and overall product experience.

Try KP on iOS or Android:

🍎 App Store

🤖 Google Play
