cirrca helps you understand the rhythm between your sleep and your days—not just how long you slept, but how you felt afterward.
FULL ACCESS REQUIRES cirrca Plus
cirrca Plus is an auto-renewable subscription sold separately. A free trial may be available. After the trial, choose:
• Monthly — $4.99/month
• Yearly — $39.99/year (Best value)
Payment is charged to your Apple ID at confirmation of purchase. Subscriptions renew automatically unless canceled at least 24 hours before the end of the current period. Manage or cancel anytime in Settings → Apple ID → Subscriptions.
WITH cirrca Plus YOU CAN:
Place your phone on the bedside table and let cirrca track your night using microphone and motion sensors. Audio is analyzed on your device and is not stored or uploaded. Wake up to a clear picture of your night: time in bed, awake periods, snoring events, and a visual timeline of your sleep.
LOG ENERGY IN SECONDS
Check in throughout the day—morning and afternoon—with a simple tap. Log from the app or respond to reminders right from your Lock Screen.
SEE THE BIGGER PICTURE
• Week and month views for sleep duration, consistency, and energy trends
• Sleep quality charts with awake vs. asleep breakdown
• Optional caffeine tracking with insights into how timing may affect your day
• Coaching tips based on your patterns
GENTLE WAKE-UPS
Set a wake alarm before bed and choose from calm alarm sounds. Stop the alarm when you're ready to start your day.
BUILT FOR PRIVACY
Sleep audio analysis runs on your iPhone. Your account syncs sleep logs and energy check-ins so your data follows you across devices—without selling your information.
cirrca is designed for everyday wellness—not a medical device. Use it to notice patterns, build better habits, and feel more in tune with your body.
ACCOUNT DELETION (Guideline 5.1.1(v))
Users can permanently delete their account in the app:
1. Sign in (demo account or create a new account).
2. Open Settings.
3. Under Account, tap Delete Account.
4. Confirm in the alert. The account and associated server data are deleted, then the app returns to the sign-in screen.
This is permanent deletion (not temporary deactivation). No email or customer-service step is required.
