Pillow review

Pillow is built around the Apple Watch. Wear it to bed and Pillow detects and analyzes sleep automatically, then shows last night's report on the watch with a heart rate analysis; you can switch to manual mode on iPhone or iPad. Reports include a stage diagram covering awake, REM, light and deep sleep, a sleep score, and audio recordings of snoring, sleep talking and other sounds, processed on the device. Trends run from a week to all time and can be compared with Apple Health categories, and mood and notes help explain bad nights. Premium unlocks unlimited history, advanced analysis, heart rate analysis, recordings, nap modes, a sleep aid library and CSV export. On the US App Store, Pillow Premium costs $39.99 a year, the lowest yearly tracker price on this list, or $19.99 a month. It is Apple-only, so Android users should look at Sleep Cycle or ShutEye.
