Naplane 2.0 — a pro upgrade for the perfect nap, still 100% offline. • Six synthesized soundscapes: brown, pink, or white noise, distant surf, a soft fan, or silence. • Wind-down breathing pacer: 4-7-8, box, or coherent breathing with a calming orb and gentle haptics. • Nap Window Planner: whether now is a prime time to nap, and the latest safe start time to protect tonight's sleep. • Achievements: eight badges to keep the nap habit going. Plus the same science-based nap-length recommender, sound bath, and melodic wake chime. No account, no network — everything runs on your device.

What's New in Naplane 1.2 Chronotype-aware recommendations. Tell Naplane whether you're a Morning Lark, Flexible, or Night Owl. The recommendation engine shifts its hour-of-day scoring to match your personal circadian rhythm - Larks get earlier ideal windows, Owls get later ones. Your ideal nap window appears on the Plan tab so you always know when to aim. Nap quality score. Every nap in your history now shows a 0-100 quality score computed from four factors: how you felt on waking, whether you ran the full planned duration, how well the start time aligned with your chronotype's ideal window, and whether the length matched your goal. The 30-day monthly summary also shows your average quality score. Melodic wake chime. The wake alarm is now a synthesized rising A-C-E arpeggio with a gentle 600 ms fade-in, generated entirely on-device. Research shows melodic alarm tones measurably reduce sleep inertia compared to abrupt beeps. The old system tone is still available as a toggle in Settings.

What's New in Naplane 1.1 Coffee Nap mode. A new nap goal that locks the timer to 20 minutes and prompts you to drink coffee first. Caffeine takes about 20 minutes to absorb, so it clears adenosine receptors right as you wake — a combination that research shows outperforms either a nap or caffeine alone. Sleep-onset buffer. Set a wind-down period (5, 10, 15, or 20 minutes) that plays before the nap clock starts. The research average for falling asleep in the afternoon is about 15 minutes — this setting makes your 20-minute nap 20 minutes of actual sleep, not 5 minutes of sleep and 15 of lying there. Nap Science guide. A new Guide tab with 18 offline entries covering the five nap lengths and their sleep stages, the best time of day to nap, how to avoid sleep inertia, the coffee nap protocol, and practical technique tips. Every entry cites the original research.
