Radii - Wear OS Watch Face

About this app

The motion of our planet along its orbit and around the sun brings time to pass in our realities. We were quite intrigued by this fact and decided to recreate this idea in our next watch face.

Radii takes inspiration from the dynamics of a planetary system and simulates its workings onto a digital timepiece. The centre—our star—indicates the hour while a sphere carrying the minute rotates around it along its striped orbit. You will also see a tiny moon gliding around this sphere in sync with each stroke of the second hand.

What’s more? The watch face also has a scale that displays your battery life and a crescent that shows the day.


In the event that the watch does not automatically notify you to set up Radii you can manually do so by following these steps:
• On the watch, open Play Store
• Scroll down until the section "Apps on your phone" appears. You should be able to see Radii listed under this section.
• Under Radii, tap on "Install". Once it is installed, select "Set Watch Face".

Ratings and reviews

Neat design, basic color controls are plenty. It would be nice to change the size/scale perhaps. But the lack of good burn-in protection is bothersome. I don't feel right using this on an amoled screen for long periods as some of the larger, always-lit sections do not follow burn-in prevention methods. An outline ambient mode or similar option would make this a daily-use face as almost all watches are amoled now.

Can you add an always on display mode where you remove the battery and day elements, so only the clock face is showing? I think that would make the watch face essentially perfect in my opinion, I really like the spacial design of it & adding this would allow it to be really minimal, reducing the battery usage and helping with screen burn in. Could allow pressing the day to be interactive and take you to the calendar app like complications do, but mainly the AOD change would be amazing!

Really like this watch face. Been using it for months now. Very sleek and nice to look at. It doesn't drain your battery either like other watch faces do which I really like. I would definitely recommend this watch face if you're looking for something simple but a nicer looking than some of the built in faces
