AutoSleep vs BioPulse

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.

Smoking cessation and heart-rate tracking web app that uses a 15-second face scan to show nicotine’s effect on the body, paired with a 30-day quit/cut-down plan.

• 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

• Uses phone camera, no wearable or app store download needed
• Short daily actions make quitting feel manageable
• Visible pulse feedback after smoking vs calm baseline is motivating
• Tracks cravings, streaks, health wins, and money saved

• 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

• Camera-based heart rate and HRV estimates can be inaccurate
• Not a medical device and does not diagnose or treat
• $11.99/week after a 3-day trial is expensive for a wellness tool
• Requires front camera permission; blocked camera stops the core experience
