NemuriLab is a sleep coach that finds what actually works for YOUR sleep — using your own data. Most sleep apps only measure or play sounds. But what you really want to know is: "so what should I actually do?" NemuriLab logs the habits you can change (your "levers") alongside your sleep quality, and figures out which levers truly move your sleep. Try everything free for 7 days. No account. All data stays on your device. No wearable required. DISCOVER YOUR LEVERS Late caffeine, screens in bed, late meals, naps, exercise... NemuriLab quietly analyzes which ones affect your sleep onset and restfulness — like "in your data, caffeine after 10pm shifts your sleep onset by about 27 minutes." Your personal answer gets clearer the longer you log. SEE YOUR SLEEP DEBT The gap between the sleep you need and the sleep you get, scored every day. TODAY'S ENERGY PLAN From your wake time, NemuriLab suggests your focus peak, afternoon dip, best nap window, and caffeine cutoff — based on the two-process model of sleep science. A ROUTINE TO SLEEP, AND HELP FOR SLEEPLESS NIGHTS A pre-bed wind-down checklist and a dark-screen breathing mode. For nights you just can't sleep, a gentle SOS flow. BUILT TO KEEP YOU GOING Collectible cards and full-screen celebrations as you keep logging, plus a new seasonal theme each month. Share your discovered levers (with a privacy mode that hides the numbers). YOUR DATA IS YOURS 100% offline. No account. No tracking. CSV export and backup for phone transfers. NEMURILAB PRO (auto-renewing subscription) $3.99/month or $29.99/year with a 7-day free trial. Required for logging and analysis. Viewing and exporting past data stays free. Cancel anytime in your App Store settings. Payment is charged to your Apple ID and renews automatically unless canceled at least 24 hours before the period ends.
