I started development of a new app and thought it would be neat to blog about while development.

The idea is simple. Time in daylight is a new value tracked in the Health app. This is automatically done on watchOS 10 on Apple Watch SE (2nd generation), Apple Watch Series 6 and later, and Apple Watch Ultra.

Go Outside app reminds you to go outside, compare yourself with friends, streaks, and more.

Current state:

  • gets data from HealthKit
  • shows progress of today
  • shows progress of last seven days
  • segmented control to switch to streaks view
  • navigation to Sharing, Settings and Awards
  • in Settings you can set your daily goal

Go Outside on day 1. Summary view.


I am using the new Observation framework and it is total bliss. Looking forward to work with SwiftData and other new frameworks/improvements.
