Editor's Overview

Below you'll find the publisher's own description, a quick spec sheet, and a short buyer-beware checklist so you know exactly what you're installing before tapping download.

Install Checklist

Only download through the button on this page — never from third-party mirrors or shortened links, which are the most common way malware spreads.
File size is a light 8.77 MB, so it installs quickly even on modest connections.
This build is signed by "ProfessorQuantumUniverse" — always verify the developer name matches what's listed on the app's official store page before installing an update.
After install, Android may prompt you to allow "Install from unknown sources" — approve only this one install, then revoke the permission in Settings > Apps > Special access.
We link directly to the APK file or the publisher's repository; we do not modify the binary. Always run a virus scan after any sideloaded install.

About this app

reReminder keeps you in the loop. Set up as many recurring reminders as you need — a nudge to correct your posture, a break every hour, water, medication, a Pomodoro timer, and let each one run on its own schedule.

Several reminders, side by side

Run "Take a walk" every 50 minutes and "Sit or stand" every 20 minutes at the same time. Every reminder has its own interval, name, message and color, and counts down independently, changing one never disturbs the others. One master switch pauses everything and shows you which reminder is up next.

Reminders that fit your day

Limit a reminder to certain weekdays and to a time window, for example Monday to Friday between 08:00 and 17:00. Windows may cross midnight for night shifts. Outside its window a reminder stays quiet and tells you when it starts again. Schedules are optional, a new reminder simply runs at any time.

Notification text that writes itself

Drop values into your message, and they are filled at the moment the reminder fires: the current time, the date, the weekday, the reminder's name, its interval, or when the next one is due. A live preview shows the result while you type.

Made to actually fire

reReminder uses exact alarms that survive Doze, reboots, app updates and timezone changes, and it arms the next alarm before it even shows the current one, so the loop cannot break. A reliability check in the settings tells you whether the system is holding your reminders back, and takes you straight to the setting that fixes it.

Features:

Unlimited reminders: each with its own interval, from one minute to many hours.

Schedules: pick weekdays and a daily time window per reminder.

Dynamic text: insert time, date, weekday, name, interval or next due time.

Text-to-Speech: have your reminder read aloud, in your device language.

Personalized alerts: choose a notification sound or vibration pattern, and mute either one per reminder.

Master switch: pause everything at once without losing your setup.

Material 3 design: dynamic colors on Android 12+, full dark mode.

English and German, with per-app language support.

Private by design: no ads, no tracking, no accounts, no network access. Everything stays on your device. reReminder is free and open source.

🇪🇺 Made with passion in Europe.

Yes. The APK file linked from this page is free. The developer may offer in-app purchases once installed, but obtaining the installer itself costs nothing.

What Android version does reReminder require?

Is reReminder safe to install?
