MADE FOR THE IN-BETWEEN
Not every night
looks the same.
Sleep Keeper is a manual sleep journal for fragmented sleep. You mark the transitions. It adds up the sleep blocks you've logged, keeping the awake stretches separate.
No scores to chase. Just a clearer record of your night.
Wake. Pause. Return.
Tap I'm awake to mark an awake interval, then Back to sleep when you're ready. Check your total without ending the session.
See how it adds up.
End your session to review its blocks. Revisit your history and correct a logged duration when you need to.

YOUR NIGHT BELONGS TO YOU
A journal.
Not an audience.
The current Android prototype stores your sleep journal in its own private app storage on your phone. No account, advertising, analytics, or internet permission.
It doesn't use your microphone, camera, or other sensors to guess when you're asleep. Your entries are your own estimates.
An honest limit: backups include completed sessions only and are unencrypted. Choose a private export destination. Uninstalling the app or clearing its data removes its local journal and internal safety copies.
Read the privacy policyA FEW QUIET ANSWERS
Before you
turn in.
Does Sleep Keeper detect when I'm asleep?
No. It's a manual journal. You start the session, mark awake intervals, and resume when settling back down. It doesn't measure sleep stages or automatically detect sleep. Awake time you don't record stays included in the logged total.
Can I download it yet?
Sleep Keeper is currently an Android development prototype, not a public app-store release. We'll add an official download link here when a public build is ready.
What will Sleep Keeper cost?
The planned launch price is $2.99 for a one-time app purchase, including three themes. Additional themes will cost $0.99–$1.99 each and are optional, with no subscription. Purchases aren't available yet; Deep Night, Ember and Biolume are included. Optional theme purchases are planned for a later update.
What if I forget to mark an awake interval?
Only the awake intervals you record are subtracted. Completed sessions let you correct a block's logged duration, with edited durations marked. It remains an estimate based on what you enter.
Is this a medical sleep tracker?
No. Sleep Keeper is a personal logging tool. It doesn't diagnose conditions, measure sleep stages, or provide medical advice.
