FOSS reminder app recommendations with persistent notification
Hello! I'm currently very very dependent on TickTick (not tiktok) because of a single simple feature: persistent notification alerts. I can set events and tasks as in many other similar apps, but once the reminder is triggered, a persistent notification is showed, until I manually say "mark as completed" or "remind me later". This way I avoid accidentally removing (and missing) it by clearing my notification tray. However, it is closed source and only available on Google Play. I'd like to replace it (if possible) with a FOSS app. Do you know of an app with this feature?
Thanks in advance Android folks!
