AutoSleep vs Runtastic

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.

Runtastic is a comprehensive fitness tracking application designed to help users monitor and improve their physical activity. By leveraging built-in GPS, it records routes, speed, distance, and elevation for running, walking, cycling, and other outdoor sports. Originally an independent fitness app, it became a cornerstone of the Adidas digital running ecosystem, offering personalized training plans, audio feedback during workouts, and a vibrant community platform to share achievements and set fitness goals.
