May it be of help.
And may you sleep healthier.
See around 7 days of past sleep right after downloading — no waiting, your sleep report is ready the moment you open the app.
The app automatically tracks your night-time sleep — bedtime, wake-up time and sleep duration are recorded on the timeline.
Your animal rating is based on sleep between 9 PM and 9 AM — Lion, Dog, Boar, or Owl, so your sleep quality is clear at a glance.
No manual logging needed — just put your phone down and fall asleep. It works without an Apple Watch; wearing one makes tracking even more accurate.
Features:
• Sleep tracking: automatically records when you fall asleep, wake up, and how long you slept
• Animal ratings: four animals show your sleep performance at a glance
• Calendar review: every day and every sleep segment at a glance
• Home screen widget: check your recent sleep at a glance
• Monthly stats: review the whole month and find your sweet sleep time
Your sleep data stays on your device and syncs between your devices via iCloud (encrypted by Apple). We never touch your personal data.
