Building CatchCat and other small software projects.

Sharing the messy process of building apps, SaaS ideas, and learning in public.

@SoLoActavis Yes, when the Android version is working bugfree

[Sebastian Seidel @ninetofivedude]

guys please chill 😭

CatchCat got over 2,000 users on day one and my Convex backend is already fighting for its life

I built this thinking “haha funny cat app”

the cats had other plans 🐱

[Sebastian Seidel @ninetofivedude]

@VRCatalans Ahh sorry about that 😭

I got way more signups than expected on day one, so the auth/server side is struggling a bit right now. I’m already looking into it and working on a fix.

Thanks a lot for installing and reporting it. I really appreciate the patience 🐱

[Sebastian Seidel @ninetofivedude]

@michaeldcahill Good point, and you’re not the first to suggest this.

I’ll definitely keep it in mind. An opt-in rescue/adoption feature could be really meaningful later, as long as it stays privacy friendly.

[Sebastian Seidel @ninetofivedude]

Woohoo, my second app is live on Google Play 😄
CatchCat lets you collect real cats you meet in everyday life.
Camera, cat detection, collectibles, map spawns, and many bugs later, it’s finally out 🐱
Would love feedback:

@om_patel5 Thanks so much for showcasing it 😄

You described the idea better than I do half the time lol. Really appreciate the shoutout. And yes, judging by the replies, I might have to think about a dog version too 🐶🐱

[Sebastian Seidel @ninetofivedude]

@Sekharendu60107 @om_patel5 It’s already on Android 😄 I’m the developer.

You can download it here: https://t.co/gjYvARWOro

[Sebastian Seidel @ninetofivedude]

@207nbrown @om_patel5 Appreciate that a lot 😄

AI helped speed things up, but the concept, product decisions, debugging, and way too many “why is this broken?” nights were still very real lol. Glad the idea comes across

[Sebastian Seidel @ninetofivedude]

@char4n_lies @om_patel5 Yes, it is 😄 I’m the developer.

You can get it on Google Play here: https://t.co/gjYvARWOro

Currently building a web app.
MVP is almost done — just a few pieces left.
Should be ready this week.
Slowly turning ideas into reality.

[Sebastian Seidel @ninetofivedude]

Today’s struggle: fighting with the app simulator.
But I tried a bunch of things — and found a solid app idea.
Shouldn’t take long to build.
ETA: end of the week.
Let’s keep pushing.

[Sebastian Seidel @ninetofivedude]

Today’s struggle: figuring out how to build a mobile app.
New challenge unlocked.
But hey — that’s how you grow.
