CalWatch2—WearOS Calendar Face

This watch face reads your calendar and displays your agenda for the next twelve hours around the watch dial, using the same colors and visibility as your real calendar. With the configuration panel, you can choose from several different face styles, as well as turning on or off the day/date block. You can additionally select any complications you wish to add to your watchface.

(Complication support require a Wear 2 or newer device.)

Installation

Once you install CalWatch2, it will show up in the list of watchfaces on your watch as well as in the Wear OS app on your phone. You can select it in either place.

A few cool features

• The calendars events shown on the watch face are exactly the calendar events that are visible from the calendar app on your phone, with the same event times and colors. If you want to change what's visible on your watch, run Wear OS app on your phone, then select "Agenda settings". Note that WearOS can take a few minutes for calendar changes to update on your watch. CalWatch2 responds as quickly as it can.

• The watch will display your calendar events within a twelve hour window. If, for example, it's 9:30am, you'll see events starting at 9:00am and lasting through 8:59pm. Any events that started before 9am but end in the visible region will still appear, but their start time will be clipped. Likewise, any events that start in the visible region but end afterward will have the end time clipped. This clipping is shown on the watch face with the ragged edge around events at the clipping line.

• CalWatch2 ignores "all day" or any event that would make a full circle around the dial. This gives you more room to see the events that start and end in the next 12 hours.

• The second hand has a non-linear sweeping effect, similar to what you'll see in many European railroad clocks.

• Once your battery is below 33%, a yellow circle appears in the center. As the battery level drops, the circle grows. At 10% battery remaining, it turns red.

• CalWatch2 works correctly with "ambient" mode, including "low-bit" mode on watches that require it.

• If you have a "flat bottom" round watch, CalWatch2 will adjust itself appropriately.


Permissions and privacy

CalWatch2 does not transmit your personal information to anybody! CalWatch2 reads your calendar and displays it locally, but never sends anything to the network.

Why aren't my events updating?

There seems to be a bug in some newer versions of WearOS where CalWatch2 doesn't get notified when the calendar is updated. Your feedback on this is important to finding and fixing the bug. Meanwhile, you can force the calendar to reload itself by changing your watchface to something else and then back to CalWatch2. Also, CalWatch2 reloads the calendar every hour. If you see events in the "Agenda" app on your watch but not on CalWatch2, please email me with your configuration so we can try to fix it.

CalWatch2 is open source!
