Here is a tool that I use every day for over 2 years already..

Here is a little but nifty tool that I use for quite some time already. I got the idea after I listened to a Huberman Podcast episode about focus and the ultradian cycle.

The theory is that your focus peaks after ~90 minutes. So it's way harder to stay productive after that time. I found it interesting and wanted to see if that's really the case.

Minute Tracker in the Menu Bar and Example Notification After 90 Minutes

So I build this little tool. The idea is simple: track the time since my last login and display it in the menu bar in the top right (so it's less evasive). After 90 minutes I get a notification to take a break, which repeats itself every 5 minutes. (What you see in the video)

That's it. Simple and yet powerful, at least for me.
