How to set a reminder that repeats until you do it
Short answer: use a reminder app with a "nag" or "auto snooze" option, set an interval (for example every 5 minutes) and a limit, and make sure Android is allowed to ring it on time. Normal reminders ring once; a nag reminder keeps going until you tap Done.
Why one alert isn't enough
The most common complaint about reminder apps is simple: "it reminded me once and I forgot anyway." You swipe the notification away because you're busy, and nothing brings it back.
Step by step
- Create the reminder with a clear action in the title ("Call the dentist", not "Dentist").
- Pick the time. Typing "3pm thu" or "in 45m" is faster than scroll wheels.
- Turn on repeating alerts: choose how often (1, 5, 10, 15, 30 or 60 minutes).
- Choose how many times: 3, 5, 10, or until done.
- When it rings, tap Done to stop it, or snooze it +10 minutes or +1 hour.
Make sure it actually rings
Allow "Alarms & reminders" for the app so it can ring at the exact minute, and set battery usage to "Unrestricted" on phones that put apps to sleep.
An app built for this
Naglet does exactly this: every reminder can re-alert every few minutes until you tap Done, right from the notification.
FAQ
Can the built-in Clock or Google reminders repeat until done?
Not really. Alarms repeat on a schedule, and Google reminders notify once. Neither re-alerts every few minutes until you confirm.
How often should a reminder repeat?
Every 5 minutes works for most tasks. Use 1 minute for things like taking food off the stove, and 30–60 minutes for chores you can do any time today.
Won't constant nagging get annoying?
Set a limit (3, 5 or 10 repeats) for everyday items and save "until done" for the few things you truly can't miss.
