NapNap App vs Steady

NapNap App was created to aid a friend suffering from nightly nightmares. NapNap App helps you sleep better by quietly tracking your heart rate overnight. If your heart spikes or stress rises, it gently vibrates to help you settle. Wake up refreshed with clear insights into your sleep quality. Choose your own heart rate limits and let NapNap watch over your rest. If your heart starts racing during a nightmare, gentle wrist vibrations help ease you back into peaceful sleep, without waking you fully. No data is transmitted. All data is stored locally on your Apple Watch. Once downloaded, this app can be used offline, anytime, anywhere.

Steady is built for shift workers, not 9-to-5. NEW IN 1.8 • A 3-minute reaction test before you drive home, compared with your own rested speed. A fatigue check, not a driving test. • Switching to nights or back to days: Steady plans the days around it, with bedtimes, light and a nap before the first night. • Your next 24 hours on one line: work, sleep, naps and your caffeine cutoff. • iPhone Duo: stand it half open and Steady becomes a nightstand. WHAT MAKES STEADY DIFFERENT • Drive home risk alert: warns you when fatigue makes the drive too risky. 17 hours awake is roughly a 0.05% BAC. Always free. • Roster import from a photo: point your camera at the schedule on the wall and confirm every day before it's saved. • An alertness curve that shows when you'll crash, plus the best windows for exercise, meals and light. • A sleep score measured against your own rotation, not a 9-to-5 clock. • Sleep debt and a payback plan built around your real rota. • Smart wake alarm: wakes you in light sleep within a window you choose, backed by a real system alarm on iOS 26 and later. • 290 coaching tips grounded in AASM, NIOSH and chronobiology research. • English and Spanish, written natively in both. • Private and on-device: no accounts, no servers, no tracking.
