Capybara: Loud Alarm Clock
Math Puzzles & Sleep Recorder
Only for iPhone
Free · In‑App Purchases
iPhone
A loud alarm that won’t stop until you finish a task: math, memory, shaking, steps, or push-ups and squats counted by the camera. Plus sleep tracking every night.
A loud alarm clock that won’t stop until you solve a math puzzle—and a sleep recorder that captures your whole night.
Capybara Sleep rings at your iPhone’s full volume and turns off only after a task, from math to push-ups and squats counted by the camera. While you sleep, it records snoring and sleep talk you can play back in the morning, then shows how well you slept.
No watch, fitness band, or extra device required—just place your iPhone near your bed when you go to sleep.
AI-POWERED SLEEP INSIGHTS
Capybara Sleep uses your iPhone’s microphone and on-device AI to analyze patterns in nighttime audio while you rest.
— Estimate periods of light sleep, deep sleep, and wakefulness based on sound
— See a sleep score for each night
— Track sleep debt and understand how much rest you may need
— Get personalized recommendations based on your sleep history, bedtime, wake-up time, and sleep goal
— Use the smart alarm: a recommended wake-up time based on your past nights, with a gentle volume rise
DISCOVER YOUR NIGHTTIME SOUNDS
Capybara Sleep records and organizes nighttime sounds so you can find and replay moments when you snored, talked, coughed, laughed, or heard other disturbances.
Your recordings and audio analysis stay on your iPhone. They are processed locally and are not uploaded to our servers.
AN ALARM THAT HELPS YOU STAY AWAKE
Ever turn off an alarm without fully waking up, only to fall right back asleep? Capybara Sleep can require a quick challenge before the alarm is dismissed:
— Do some math
— Memorize a sequence of capybaras
— Shake your iPhone
— Walk around the room
— Tap the capybara a set number of times
— Do push-ups or squats counted by the camera
RELAXING SOUNDS AND MUSIC
Create a calming bedtime routine with:
— Nature sounds such as forests, ocean waves, and a crackling fire
— Meditation music and ambient sounds
— Your own imported audio tracks
Set a sleep timer and playback will stop automatically after the selected time.
DETAILED SLEEP REPORTS
Each morning, review a detailed summary of your night:
— A timeline of estimated light sleep, deep sleep, and awake periods
— An overall score based on sleep duration, quality, and efficiency
— Recorded sleep sounds organized by category
