Waifu Alarm: Clock & Timer

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.
