## What is Sleep Sheep?

Every alarm tells you when to wake up. Sleep Sheep also tells you when to go to bed. You choose when you want to get up, and it calculates your ideal bedtime based on your sleep cycles (~90 min). All on your iPhone, with no accounts or servers.

PLAN WHEN TO GO TO BED
- Pick when you want to wake up and we'll calculate your ideal bedtime based on your sleep cycles (~90 min: 4, 5, or 6 cycles).
- Fine-tune how long you take to fall asleep for a more accurate recommendation.
- We'll notify you ahead of your set time so you can get ready for bed and stay on track with your sleep cycles.

WAKE UP AT THE RIGHT TIME
- Multiple alarms with day-based repeat, snooze, gradual wake-up, and customizable sounds.
- Reliable, system-integrated alarms, visible on your lock screen.
- Nap mode with the duration you choose.

REVIEW YOUR SLEEP, STRESS-FREE
- History and journal synced with Apple Health (reads your sleep; saves your hours only if you want).
- Trends by day, week, and month, with a recovery view and a quick daily log.

YOUR DATA, ONLY YOURS
- No account or servers: your profile, alarms, and preferences live only on your iPhone.
- Export and import everything as a JSON file whenever you like.
- 'Start fresh' erases your local data and cancels alarms instantly.

AND MORE
- Short tips on sleep and cycles, plus a built-in help center always on hand.
- Light and dark theme. Available in Spanish, English, German, French, and Italian.

The alarm that doesn't just wake you up: it also tells you when to go to bed. Download Sleep Sheep and start tonight.

IMPORTANT
Sleep Sheep is a wellness app. It does not replace professional medical advice and does not provide diagnoses. If you have persistent sleep problems, consult a healthcare professional.

Requirements: iPhone with iOS 26 or later. Notifications and Apple Health are optional but recommended for the full experience.
