About

SleepCore

Features
Read full description

SleepCore tracks your nights and naps with honest scores, a Smart Wake window, and Benny, the Australian fur seal who lives on the steps of the Opera House in Sydney Harbour and has opinions about your 5-hour Tuesday. WHAT IT DOES Log sleep, watch trends, and get a gentle bedtime nudge if you want one. Benny keeps the tone human and friendly. - Sleep & Nap Tracking Log any session, full nights or power naps. Set a bedtime goal, tap Sleep or Nap, and SleepCore does the rest. - Morning Report Benny reacts first. Then your scores, estimated sleep stages, session signals, and a quick mood + tag check-in. Thirty seconds. - Three AutoSleep-style Scores Readiness, Quality, and Consistency: calculated from your logged hours and consistency, not sensors. Clearly labelled as estimates. - Smart Wake Window Set a latest wake time and a phase window (20, 30, or 45 min). SleepCore shows when to surface for lighter sleep based on 90-min sleep cycles. Display mode, no alarm fire yet. - Sleep Log & Trends 7, 30, and 90-day averages. Night-over-night bar charts. Nap totals. See whether this month was actually better than last. - The Pod Keep your streak and unlock real Australian sea creatures — from a Common Little Penguin to a Legendary Golden Benny. Eight total, each with a genuine fun fact. - Bedtime Reminder One optional local notification at the time you choose. No marketing, no server pings. Off anytime in Profile. HONEST BY DESIGN SleepCore doesn't use your microphone, camera, heart rate sensor, or Apple Health. Session signal estimates (Stillness, Recovery Index, Breath Rhythm, Rest Environment) are modelled from your logged data, not hardware readings. This is clearly displayed in-app on the Sources screen. Scores draw on public sleep health guidance from the CDC, NIH, and the American Academy of Sleep Medicine. BENNY Benny represents Sydney Harbour's laid-back energy. He'll tell you "Now THAT'S how you do it" after a deep eight-hour night and "Mate. That was a coma." after a 90-minute nap. He's personality, not a sleep lab. GUEST MODE & PRIVACY No account required. Use SleepCore as a guest: all data stays on your device. Create an account with Supabase to enable cloud backup. We never sell your data, never use it for advertising.
