If you have a server with CRON jobs do yourself a favor: Add them to a Sentry monitor ✌️ I don't want to learn about failures from my users.

I’ve tried a lot of React Native tools over the years. Most are fun for a week. A few made it into my daily workflow. I made a video about the ones I actually use to save time when building apps 👇

Testing a game is fun 🙃 You need to cover different platforms, different player levels, different devices... Think I need to figure out how AI can do all of that - any idea where to start the automation?

Running a Product Page Optimization test for the first time ✌️ My games CR isn't great, and instead of randomly trying things, I made a test in ASC: - Original page - Simply a new preview video - New screenshots Traffic split equally between the 3, let's see if there are any meaningful trends!

Not the most popular keywords, but trying to grow on some new ones like "acres" and ranking better on "stardew valley" ❗️Note: Don't directly use a competitor keyword or you get in trouble

Dear app store gods, please let this be another upswing and not just a few good days 🙏

My game finally hit $5,000/month. For a few weeks, I thought: “Nice, this is my new normal.” Then installs dropped again. Why? 👇

It's crazy how Fable creates these mockup + explanations for redesigning my game. Absolutely love what's possible today.

June 2026 income report for my mobile game Tiny Harvest 🌽 💰 $5,831 revenue 👥 6,145 new players Still blows my mind that this little farming game is becoming a real business.

Time to set up the next Tiny Harvest Season 😎 As always also creating an Apple Event. Easy way to get more attention!

Simon Grimm @galaxies.dev · 29/06/2026

Definitely seeing a relation between Apple giving Tiny Harvest traffic and in-app purchases. Distribution really is everything.

I built an AI voice notes app with React Native. And AI agents wrote most of the code. Call me a vibe coder, but this is how you build great apps in the age of AI 👇

Are you building apps with React Native? You should probably target TV devices - it's one of the best choices you can make 👇

I reviewed 3 React Native apps from the community. No AI slop. Just real apps.

"Pay 2 win." Every player hates these games. Every indie dev fears these comments. And yet here I am, telling you that it’s probably the best way to monetize and actually make money with your app. Here’s why I still use in-app purchases in my game 👇

How hard is it to run a mobile game alone? Harder than building the game itself. Because building is just one part of it 👇

You can't please everyone with your app 🤷‍♂️ It's something I recently learned, no matter what you do!

Finally, prepare for slow days 🫥 It's not always trending upward. I had days with just a handful of sales, and I had $300 days. Most likely my April will be slower as I have only 1/5 of the downloads again.

Simon Grimm @galaxies.dev · 08/04/2026

Even if you don't like IAP...people are used to them 🤷‍♂️ Everyone knows the meaning of diamonds as premium currency. Everyone has seen a season pass before. Everyone loves a highly discounted starter pack. Even if you as dislike micro transactions, they are still one of the best monetizations ✌️

Simon Grimm @galaxies.dev · 08/04/2026

Sometimes you get lucky! For a short period, downloads jumped from ~30/day → 150–200/day. I had no idea what changed, but most likely: Apple pushed/featured the app, as the "App Store Browse" was way higher than usual. Apparently that didn't last long - let's hope I can get their again soon 😂

My indie game made $2,500. Not life-changing… but enough to completely change how I think about building apps. Here’s what it learned so far 👇

Simon Grimm @galaxies.dev · 02/04/2026

I made a tiny change to my App Store page… and suddenly more people started downloading my game 😍 Your App Store page decides if people even try your app 👋

I lost over half my players in the first 10 minutes of my game. This is how I (hopefully) fixed the leaking bucket 😅

Launched my first live community event 🐰 For 14 days, players can find random eggs on their farm and get rewards, while working together on the global goal of collecting 100k eggs 🔥 Might have set the number a bit low, the game has been growing rapidly lately 🙃

AI one-shot a retention analysis for Tiny Harvest 🔥 These are the moment where I truly love the progress of AI. This would have taken me hours, if I had actually pulled together the right data and libraries for the charts. It took less than 3 minutes.

Spent hours debugging a crash in my app. Turns out it was caused by the iOS Reduce Motion accessibility setting. A reminder that real-world users run your app in environments you never test 😅

I built a Fire TV app with React Native 👀 Not mobile. Not web. An actual TV app using VegaOS. Here's how to get started 👇

I built a mobile idle game in under 60 minutes this weekend. It's completely terrible. But shipping something playable in an hour with React Native + Expo is still wild.

What would I change in my next app? Here are 3 things I would do different if I started Tiny Harvest today 👇

My new best friend - Xcode debugging tools. When playing my game (or just keeping one screen idle) I am/was at high energy impact and constant CPU usage, which drained a lot of battery. Now debugging this by commenting out single tabs/views/components to check their impact on CPU in real time.

The State of React Native survey results are absolutely wild: 🥇 #1 Video Creator 🥈 #2 React Native Podcast 📚 Galaxies mentioned among the places developers learn React Native and @expo.dev Honestly pretty crazy. Thanks to everyone building with React Native and being part of this community 🙌

I absolutely regret that I didn't use this feature earlier. Gems. Diamonds. Tokens. Every app currently has some kind of virtual currency. Implementing them used to be… kinda annoying. RevenueCat just made this way simpler 👇

How the referral mechanics in my game technically works ✌️ Spoiler: It's actually quite easy to set this up if you have the right backend structure!

Simon Grimm @galaxies.dev · 24/02/2026

The only thing I don't like about AI in Tiny Harvest: The routing for my game is a mess. How would you structure routes with Expo Router when essentially everything is just a modal/page pushed from a tab, no deep nesting? PS: The screenshot is just the start of a list with about 170+ pages...
