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.

In this video, I share the tools that have become part of my daily workflow, including: - @expo.dev Orbit - Quick Push - Buoy Devtools www.youtube.com/watch?v=Pyp...

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 👇

TIL Expo now has its own SQLite DevTool 😍

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?

Simon Grimm @galaxies.dev · 12/07/2026

I don’t think Tiny Harvest needs another feature right now. It needs more people to find it. That’s a much harder problem to solve.

Long run this morning. One nice thing about marathon training: Even if work feels chaotic, you get one clear win for the day.

With all the evidence it's just sad to see so many people saying "I need to start running again to lose weight" while actually the opposite of it is true. Don't make it harder for yourself then it has to be!

000

Simon Grimm @galaxies.dev · 10/07/2026

Sport is important when losing weight, but more in a sense that you maintain muscle. If you want to have an easier time, just get to 10-20k steps daily (walking pad!) and eat healthy.

110

Simon Grimm @galaxies.dev · 10/07/2026

If you want to lose weight, doing more sports is rarely the answer. It's 95% about what you eat. When I actively train, I am so much more hungry all the time that I have a hard time staying in a deficit at all.

Simon Grimm @galaxies.dev · 10/07/2026

Tiny Harvest deserves players regardless of whether it gets featured. Time to build my own distribution 🔥

010

Simon Grimm @galaxies.dev · 09/07/2026

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!

000

Simon Grimm @galaxies.dev · 09/07/2026

I have to set up a new Google dev account and transfer my game 🙈 Wish me luck in the migration. Will share how I did it and whether it worked!

010

Simon Grimm @galaxies.dev · 08/07/2026

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

110

Simon Grimm @galaxies.dev · 08/07/2026

Current priorities: ✅ August season ✅ Bugs & QoL ✅ TikTok ✅ Reddit ✅ X Trying really hard not to hide behind “just one more feature.”

Simon Grimm @galaxies.dev · 07/07/2026

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

000

Simon Grimm @galaxies.dev · 07/07/2026

I break down the whole story in my latest video. My biggest takeaway wasn’t how to make $5k. It was about the distribution of my game. www.youtube.com/watch?v=KOe...

000

Simon Grimm @galaxies.dev · 07/07/2026

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

110

Simon Grimm @galaxies.dev · 06/07/2026

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

110

Simon Grimm @galaxies.dev · 06/07/2026

The next few months I’ll probably spend just as much (or more) time on marketing as I do writing code. Weird shift, but it feels like the right one.

Crossed 500 App Store ratings with Tiny Harvest 🥳

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.

Simon Grimm @galaxies.dev · 30/06/2026

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

000

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 👇

Not every season is for building. I wrote about a quarter where Tiny Harvest was growing, but it still felt like I built almost nothing 👇 simongrimm.dev/the-quarter...

The Quarter Where I Built Almost Nothing

Tiny Harvest was growing, YouTube was changing, and life felt uncertain. A reflection on the quarter where I built almost nothing.

Simon Grimm @galaxies.dev · 17/06/2026

When you suddenly remember how work feels after being occupied with life.

Simon Grimm @galaxies.dev · 12/06/2026

My latest video about AI thoughts seems to resonate with many of you. It’s about what AI has changed for me, why I’ve been building indie apps instead of courses lately, and why my YT channel is changing. Maybe we’re all figuring this out together.

In this video I'll walk your through the process of transforming a React Native app with @Expo to a monorepo with Vega OS TV App. You’ll learn: • How to install Amazons MCP and AI Builder Tools • How to refactor your app with AI • How to build a TV native app www.youtube.com/watch?v=j4V...

Simon Grimm @galaxies.dev · 02/06/2026

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

100

Simon Grimm @galaxies.dev · 05/05/2026

Can you build great apps with AI? Of course! And here are some great examples + what i would improve 👇 www.youtube.com/watch?v=dJw...

Simon Grimm @galaxies.dev · 05/05/2026

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

110

Simon Grimm @galaxies.dev · 23/04/2026

Curious how others think about this - especially from people who tried different models ✌️

000

Simon Grimm @galaxies.dev · 23/04/2026

If you want to build something long-term, you need a model that keeps you going. I wrote down how I think about it: simongrimm.dev/why-i-use-i...

Why I Use In-App Purchases in My Mobile Game

Every player hates pay-to-win. Every indie dev fears it. So why do I still use in-app purchases in my game Tiny Harvest?

100

Simon Grimm @galaxies.dev · 23/04/2026

"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 👇

120

Simon Grimm @galaxies.dev · 21/04/2026

I built a mobile game completely by myself - no team, no studio, just me. In this video I'm breaking down the full experience: - what went right - what went horribly wrong - what I'd do differently ...and whether it was actually worth it 🤷‍♂️ www.youtube.com/watch?v=wGi...

000

Simon Grimm @galaxies.dev · 21/04/2026

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

Simon Grimm @galaxies.dev · 19/04/2026

Received my very first invoice from @RevenueCat this week after years of using it. Happiest $36 I ever paid 🥰

Simon Grimm @galaxies.dev · 16/04/2026

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

010

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

For April, I plan to finally add more depth to the game after many QoL releases. I'm so excited to implement the new features and can't wait to build out my own game world more, one small feature at a time 💚

010

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

Overall I'm super happy with the trajectory of the game: - Discord has grown to almost 300 members - The game has almost crossed 4,000 players - Conversion and retention rates look healthy

100

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

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.

100

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

I also messed up my user retention by basically having no onboarding 🤦‍♂️ Don't just slap an intro slider on your app and call it a day - actually walk them through the first 3-5 minutes. Design what they should see, which wins they should have. Here's what I did 👇 x.com/schlimmson/...

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

You Appstore page and ASO is the most important piece to convert people. Tweak that part before anything else - I shared some thoughts about it here 👇 x.com/schlimmson/...
