AutoSleep vs Yuka

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.

Yuka is a mobile app that lets users scan the barcode of a food or cosmetic product to get an instant, independent health rating. For food, it evaluates nutritional quality (additives, sugar, salt, fat) and flags concerning ingredients; for cosmetics, it checks for endocrine disruptors, irritants, and allergens, then suggests healthier alternative products with a better score. Yuka positions itself as 100% independent, with no advertising and no funding from the brands it rates, funded instead through its optional premium membership. The app reports over 8 million users, a 4.8/5 average rating across 500,000+ reviews, and is a certified B Corporation.
