AutoSleep vs Runna

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.

Runna generates personalized running training plans for any distance from 5K to ultramarathon, adapting workouts based on a runner's goals, experience, and schedule through what it calls the Runna Engine. Plans include guidance on running form, nutrition, injury prevention, and complementary strength and mobility training. The app syncs with Garmin, Apple Watch, COROS, Fitbit, Suunto, and Strava so completed workouts feed back into the training plan. It holds a 4.9-star rating from more than 76,000 App Store reviews and a 4.7-star rating on Google Play.
