Nimits is a persistent reminder app for Android. When something is due, it takes over the screen and rings again every 5 minutes until you answer: hold to Complete, Snooze to a clock time, or Skip. Snoozes are capped, so "later" can't become "never". Write a reminder as a sentence, build routines step by step, and see what needs you first. History shows the month, including any alarm your phone blocked. No ads, no account, works offline.
