AutoSleep vs iFit

AutoSleep is a sleep-tracking app for Apple Watch and iPhone that records sleep automatically in the background, without requiring the user to start or stop a session. It uses heart rate, motion, and (where available) blood oxygen and wrist temperature data to estimate sleep stages, sleep quality, and a running sleep debt total called the sleep bank. The app integrates with Apple Health and HomeKit, offers a smart alarm that wakes users during a lighter sleep phase, and includes an add-on companion app, AutoSnore, for snore detection. It is sold as a single one-time purchase on the App Store rather than a subscription, and processes data on-device rather than through a cloud account.

iFit delivers on-demand video workouts led by certified trainers, covering cardio, strength, HIIT, yoga and recovery. The library updates weekly and syncs with compatible fitness equipment for an immersive experience. Users can track performance metrics, follow adaptive training plans, and stream sessions on phones, tablets, smart TVs or directly on connected treadmills and bikes. The platform offers a free trial and a subscription model that unlocks the full catalog and personalized coaching.
