Alarm Clock for Heavy Sleepers

Fexo Alarm Clock for Heavy Sleepers: loud wake up alarm with math challenge App.
Sleeping through every morning? Fexo brings you a smart alarm clock built for one job: getting you out of bed. This is the alarm clock for heavy sleepers that keeps ringing until your brain is truly awake, then proves it with a quick wake up alarm task before it lets you dismiss.
⏰ A SMART ALARM THAT KNOWS WHEN TO RING
Set a smart wake up window and let the smart alarm track your sleep with your phone’s motion sensors. It picks a moment of light sleep inside your window, so the wake up alarm feels gentler even on early starts. Create repeating, one time, date specific and rotating shift pattern alarms, or simply say “7:30 tomorrow” and the voice alarm sets itself.
🧮 DISMISS CHALLENGES THAT ACTUALLY WAKE YOU UP
Turn every morning into an alarm challenge. The math alarm clock mode makes you solve equations, or pick memory, typing, shake, sequence, steps, photo match, QR code or barcode scanning, each with four difficulty levels. With anti dismiss mode on, completing the challenge is the only way to stop the ringing, and a wake up check pings you a few minutes later to confirm you have not crawled back under the blanket. Snooze limits, challenge to snooze and challenges that get harder with every snooze keep the snooze button honest.
🔊 A LOUD ALARM CLOCK FOR THE DEEPEST SLEEPERS
Loud Mode pushes the volume to maximum for a true loud alarm for heavy sleepers, with gradual volume fade in, custom vibration patterns, a flash alarm that blinks the camera flashlight, and screen brightness that rises while it rings. Choose any alarm ringtone from the built-in tones, use your phone’s ringtones, or import audio and enjoy an alarm clock with your own music and song ringtones. Prefer words over music? Text to speech reads your alarm label aloud, so it is also an alarm clock with loud sound and a voice you cannot ignore.
😴 FROM POWER NAP TO NIGHT CLOCK
Recharge with a power nap timer (10 to 60 minutes or custom), set a quick “wake me at” power nap alarm, and fall asleep to calming sleep sounds that keep playing offline after the screen turns off. While you charge overnight, the dim bedside night clock always on display style mode protects your screen from burn in and shows the time at a glance.
📈 THE FEXO DIFFERENCE
Fexo Smart Alarm comes with alarm presets for work, university and workouts, home screen shortcuts for naps and voice alarms, and wake up insights with stats, a weekly chart and full alarm history. The Fexo reliability check walks you through battery optimisation, Do Not Disturb, alarm volume and notification permission, so this alarm app rings when it matters. It is a lightweight apk, quick to download and kind to your battery.
