The next sleepy window. A report for the clinic.

What other trackers don’t lead with.

Built for 3 a.m. — a hint after the nap, a page for the doctor, and nothing that requires an account.

• Sleepy window After a nap, a hint for when they may be ready again — from age and the sleeps you already logged. An estimate, not medical advice.
• Clinic-ready report One page for the pediatrician, plus 14-day curves. The log you already kept, not a spreadsheet you rebuild at 11 p.m.
• On this iPhone No sign-in to start. Records are encrypted on the device. Optional PIN — we cannot reset a forgotten one.
