About

Daylight Tracker

Read full description

Daylight helps you become more aware of your time in daylight, so you can build routines that bring balance and energy to your day. In northern countries, especially during darker months, it’s easy to spend most of the day indoors. Daylight helps you notice how much light you actually get and reminds you to go outside when it matters most. With Daylight you can: • See your daily and weekly daylight minutes — simple, visual, and motivating. • Set your own daylight goal — choose how much time you’d like to spend outside. • Get friendly reminders — a gentle nudge if you haven’t reached your goal yet. • Sync automatically with Apple Watch — or track manually, no Watch required. • Build awareness — small moments in daylight can make a big difference in how you feel. Daylight integrates with Apple Health to read and write your daylight data. All information stays private and secure on your device. Notice your light. Find your rhythm. Feel more balanced.
