SunCalc shows the sun's day for your position: sunrise and sunset, civil, nautical and astronomical twilight, the blue hour, the golden hour and solar noon. It needs only a GPS fix, with no phone connection and no account.
- 24-hour ring: the whole day at a glance, coloured by the sun's height, with the current time and solar noon. Sunrise/sunset and civil twilight are shown below it; choose which two rows you want.
- Up/Down: look at the times of other days.
- Tap or Start: every phase of the day one by one, with start and end time. Hide the ones you don't need with Menu.
- Glance (fēnix 7 and newer, Forerunner, Venu, ...): countdown to the next sunrise or sunset.
- Works near the poles: midnight sun and polar night are shown as such.
Runs on 147 watches, from the fēnix 3 and epix to the fēnix 9, MARQ, Instinct, Forerunner, Venu, vívoactive, Enduro, Approach, D2 and Descent.
