Slowrise rises from nothing over a full forty seconds, listens for the moment you are already stirring, and tells you how the night went — without a single byte leaving your phone.
Ten ambient tones in two families. Rising tones climb from complete silence and only reach full volume at 0:40, so the first minute is a nudge rather than a shock. Steady tones reach their level in five seconds and hold it. The ramp is shaped in decibels, which is how loudness is actually perceived.
In the window before your alarm the app listens for movement and rings early if you are already in light sleep. If the app is ever unloaded, the ordinary system alarm still rings at the time you set — smart wake is a bonus, never a single point of failure.
In the morning: a sleep score, how long you slept, how much of it was deep, when you woke, and short recordings of your own snoring. Everything is deleted the moment you close the report.
