"Composer 1"-Model + "Plan-Mode" in Cursor casually one-shotting features in 2 minutes that would have taken me a couple of hours (if not days) 🤯

Just bought a domain for my upcoming Pomodoro Timer app! I opted for the cheaper version... When the app is a success, I'll try to get the "real" domain 😅

Tried to come up with a basic light mode for my upcoming Focus Timer app. I am happy with it for now, but I'm sure there will be some improvements in the future 👍

Making lots of progress on my upcoming Focus Timer app. Still, so many things to do. Hope my tight deadline wasn't too ambitious 😬

Anyone else having problems after updating their purchases_flutter package to >9.0.0? My lifetime purchases were never consumable and I still get reports from Android users that they can't restore their purchase on another device 🤔

Made the "Streaks" card configurable (which weekdays should count towards the streak and how many hours you want to focus weekly)!

Business idea for a talented designer: Make an icon library which has the same style as SF Symbols. Please tell me something like this exists. SF Symbols are great for system icons but it's heavily lacking in the lifestyle area.

Just had to think about it again: Ten months ago, my app HabitKit was featured in a "The Studio" video. This mention significantly boosted both downloads and revenue. I couldn't have asked for a better shoutout, and I'm incredibly thankful for that 🙏

The "Plan Mode" of Cursor made my productivity explode recently. It is SO much better than using the "simple" Agent mode. It 10x'ed my usage though and I'll have to pay extra soon. But totally worth it!
