Which app is better if you do not own a wearable?
Sleep Cycle is the clear choice. It tracks sleep using your phone’s microphone and motion sensors from the nightstand, so it needs no watch or band at all. Its signature feature is the smart alarm, which watches for a light sleep phase inside your chosen window and wakes you then, so you get up feeling less groggy. If you want better mornings without buying hardware, start here.
Which app is better for Apple Watch owners?
AutoSleep is built for the Watch and shines if you already wear one. It detects when you fall asleep and wake automatically, with no buttons to press, and produces detailed breakdowns of sleep stages, heart rate and a readiness-style measure. For people who sleep in their Watch and want rich, passive data, AutoSleep captures more than a phone on the nightstand can.
How much do Sleep Cycle and AutoSleep cost?
Their models differ. Sleep Cycle is freemium: basic tracking is free, and features like detailed trends and extra content sit behind a subscription. AutoSleep is a one-time purchase with no subscription, which many people prefer for a tool they will use nightly for years. Prices change, so check the current figures on the App Store before buying.
The verdict
The deciding factor is hardware. Pick Sleep Cycle if you want a gentle smart alarm and tracking from your phone alone, or you are on Android. Pick AutoSleep if you own an Apple Watch and want the most detailed automatic tracking, with a one-time price rather than a subscription. Both do their core job well; the choice is really about what is already on your wrist.
