Put science on your watch face

Science O’Clock is available on the App Store as a one-time purchase, with all 26 lessons included and no subscription. It requires an Apple Watch running watchOS 10 or later.

  1. Download Science O’Clock from the App Store, then open it on your Apple Watch.
  2. Touch and hold your watch face, then choose Edit. For the large central expression, use the X-Large face.
  3. Swipe to Complications, select a slot, and choose Science O’Clock. A rectangular complication is also available on faces with a compatible slot.
  4. Press the Digital Crown to finish, then tap the complication to open its lesson and worked calculation.

How does the expression tell the time?

A scientific number becomes a time anchor, then an adjustment brings it to the current minute. For example, π maps to 3:14; adding six minutes gives 3:20. The app puts the compact numerical calculation directly below the expression, with the answer at the end.

Scroll beyond the formula for the scientific explanation and an example. Values in the calculation are displayed to at most five decimal places.

Does the calculation update with the time?

Yes. The live calculation updates its expression, minute adjustment and answer as each minute changes. It also refreshes when you reopen or wake the app. Tapping a complication opens the current calculation. Lessons and worked examples chosen from Explore science stay on their selected calculation; use Current expression at the bottom to return to now.

watchOS controls when complications appear and refresh. If the watch face seems behind, open the app to check the current expression. If the problem persists, contact us with the face you use and the time it occurred.
