Hi 👋🏻, I’m Kerstin, an indie app developer from Germany.
I’ll share some of my work on the Focus app and would love to connect with fellow indie devs and others in the tech and design community here.

So happy to see our work featured in the App Store! ☺️
This has been a really busy summer! We carefully redesigned every part of the app. As a small team, it was quite a ride to get everything ready on day one.
That’s why I’m all the more grateful for the App Store team’s support 🫶🏻

Can any of my Apple friends please fix this bug: FB14082790
It’s been haunting us for over a year now.
And there has been ZERO feedback coming back 😭
I have provided a sample project to reproduce and a video explaining the bug.
I would even fly to Cupertino to help the team reproduce this.

Time for a break ⏰😊
The last couple of days, I was out of office due to a bad case of the flu. I find it aways difficult to get back into work mode after being away.
It’s one of those moments when I need some extra help to get back into my workflows.
Pomodoro and coffee to the rescue! 😄
