Ada is a health app that uses an AI-driven questionnaire to assess symptoms and compare them against a large medical dictionary of conditions. Users answer a series of guided questions and receive a personalized assessment report describing possible causes and suggested next steps, such as self-care or seeking medical attention.
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.
- Free to use for consumers
- Guided questioning is easy to follow for non-medical users
- Available in several languages for wider accessibility
- Backed by medical device compliance certifications
- One-time purchase price with no ongoing subscription fees
- Fully automatic tracking that does not require remembering to start or stop a sleep session
- Detailed metrics including sleep stages, SpO2, respiration rate, and wrist temperature on supported hardware
- On-device processing with no account or login required for basic use
- Not a substitute for professional diagnosis, which the app itself states clearly
- Assessment quality depends on how accurately users answer questions
- Limited transparency on data handling for the free consumer app
- Requires an Apple Watch for automatic tracking; iPhone-only use is far more limited
- Advanced metrics like SpO2 and respiration depend on specific newer Apple Watch models
- Interface and terminology (sleep bank, sleep debt) have a learning curve for new users
