About this app
PeakWatch, from Future Artifact Labs Limited, is a health and fitness app that reads data from Apple Health and turns readings from an Apple Watch into daily guidance. It looks at signals such as heart rate variability, resting heart rate, sleep, breathing, activity and recent workouts to estimate how well you are recovering and whether a day is better suited to training or rest. A Body Energy score combines sleep, recovery, activity and stress, and sleep views cover duration, consistency, stages, sleep debt and overnight vitals. For exercise there is workout analysis with heart rate zones and training load, plus more than 100 workouts across strength, HIIT, hybrid and HYROX, and you can create your own sessions. Meals can be logged with a photo for an AI-assisted estimate of calories and nutrients, and you can tag events like alcohol, illness or travel to see how they relate to sleep and recovery. An AI chat answers questions about your own data. The developer states that health data is stored and processed on the device. PeakWatch is free to download, with a PRO subscription for additional features. Version 3.1.5, released on October 21, 2026, optimized the interface layout for iPhone Duo and added shareable home page templates.
