No ads. No trackers. No spyware. No in-app purchases. Free and open source.

This is a newly rebuilt version of an app last available on Google Play in 2015, and most of the features that were once included in Sundroid Pro will be made available for free over the coming months, if supporting them on current phones is possible.

Landscape and tablet support is temporarily disabled - we're working on that!

So glad the app is back! I love the tracker and have several ways I want to use it when I'm in the great outdoors. To bad android made the notifications so difficult to program, that was my favorite feature on the old app. I've used this since my Galaxy S3 days and it worked with my S8, but I have missed it since I got my S10 last fall.

Overall it's a decent app. One disappointment is that the calendar list view either allows you to view sunrise/sunset times or duration, but not both at the same time. Very strange. It would also be nice of they included seconds in the duration since that's the actual increment of increase/decrease.

Hi Cory, enable the display of seconds in the app's settings to see durations and increments in seconds. With the extra space this requires, AM/PM time for US users, and large font sizes for accessibility, there's not enough room for sunrise, sunset and duration in one list.

Plenty of information in a streamlined format. I love the 'tracker' too. It provides a good visual aid. Twilight calendar is very useful this time of year when I'm trying to get outside and squeeze more light from these short days. The app also offers a nice choice of widgets.
