Waifu Alarm: Clock & Timer

Tuan Em

About this app

Waifu Alarm is a straightforward alarm clock for Android. It rings on time, it survives a reboot, and it will not let you sleep through it.

ALARMS
• Ring once, or repeat on any days of the week
• Label every alarm so you know what it is for
• Pick any ringtone on your device
• Gradual volume that fades in instead of jolting you awake
• Vibration, snooze with a limit, and auto-silence
• Skip the next occurrence without deleting the alarm
• Full-screen alarm over the lock screen — dismiss or snooze without unlocking the phone

WAKE-UP TASKS
Turn the alarm off only after you solve a math problem or shake the phone. Difficulty is set per alarm.

TIMER
A countdown that keeps running when the app is closed, and comes back after a restart.

STOPWATCH
Start, stop, lap.

WORLD CLOCK
Follow the time in cities around the world.

BUILT TO BE RELIABLE
• Alarms are rescheduled after a reboot, a clock change and a time zone change
• An alarm reliability screen that checks notifications, the exact alarm permission, full-screen alarms, alarm volume and battery optimisation

PRIVATE BY DESIGN
• The app holds no internet permission at all
• No ads, no analytics, no accounts
• Nothing is collected, stored or shared. Everything stays on your device and is gone when you uninstall.

Material 3 design with light and dark themes. English and Vietnamese.
