Sloth | Climbers' Alarm Clock
Un-snoozable alarm to send it
Free · In‑App Purchases · Designed for iPad. Not verified for macOS.
Tired of snoozing through your alarm? Sloth is the un-snoozable alarm clock built for climbers — and anyone who needs a real reason to get out of bed.
When your alarm fires, there is no quick dismiss. You must complete a camera-verified hang on your hangboard before the ringing stops. Mount your phone, step into frame, and prove you are actually up.
ON-DEVICE AI — PRIVATE BY DESIGN
Sloth uses MediaPipe pose estimation that runs entirely on your phone. Your camera feed is analysed in real time to verify posture and movement. No video recordings are saved. No images or video are uploaded to our servers. After the first download, detection can work offline.
ALARMS THAT ACTUALLY FIRE
Sloth is built for reliability, not gentle reminders:
• Exact alarm scheduling — wakes you at the time you set
• Full-screen wake-up — the challenge appears over your lock screen
• Foreground alarm service with wake lock — keeps ringing until you pass the challenge
• Survives reboots and timezone changes — alarms reschedule automatically
• Custom ringtones — bundled tones, system sounds, or your own audio files
• Vibration and volume control per alarm
• Daily evening reminder — a friendly nudge about tomorrow's wake-up
TRACK YOUR MORNING HABIT
Build consistency with local stats and achievements:
• Wake-up streaks and total mornings conquered
• Hang time totals and milestone badges
• Progress stays on your device — your climbing wake-up journey, your data
HOW IT WORKS
1. Set your alarm time, repeat days, and hang time
2. Grant camera, notification, and exact-alarm permissions for the best experience
3. When the alarm rings, complete the on-camera challenge
4. Only then does Sloth let you silence the alarm and start your day
WHO IS SLOTH FOR?
• Boulderers and sport climbers who train on a hangboard
• Serial snoozers who need accountability
• Early-morning gym-goers and crag-day warriors
• Anyone who wants a physical ritual instead of a tap-to-dismiss alarm
IMPORTANT SAFETY NOTE
Sloth is a wake-up tool, not a medical, coaching, or training program. Climbing and calisthenics involve risk of injury. Always use proper form, warm up appropriately, and train in a safe environment. Do not rely on Sloth as your only alarm for critical events such as medical appointments, flights, or work shifts — use a backup alarm.
Stop snoozing. Start sending.

Better screenshots. Camera starts the back camera by default instead of the front camera. Also, more in depth statistics in the stats tab.
