AutoSleep vs MacroFactor

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.

MacroFactor is a nutrition tracking app that combines macro and calorie logging with AI-powered photo food logging, letting users snap a photo of a meal to log it. It also includes calculators for bulking, cutting, and exercise-based calorie burn, positioning itself as a data-driven coaching tool rather than a static calorie counter.
