Well written! I’ve had a similar experience with a habit tracking app. I’ve once stopped using it and after getting back to it after a year or so, it was so much worse with so many new pay walled limitations. An open source habit tracker on the other hand stayed the same for years and was even improved further. If you’re inrerested: Loop Habit Tracker https://f-droid.org/packages/org.isoron.uhabits/

Thank you, I’ll try them out when I find the time :)

What did you replace it with? In my case I love my Nextcloud because I have my calendar, adress book, tasks, notes, RSS feed, etc. all in one app but I’m interested to hear alternatives to it
