I created the Battery Time Left Tile simply because the battery life on my pixel watch 2 is quite poor relative to my previous fitbit smartwatch.
I wanted to know how much time left I had before I needed to charge the device. Luckily, the wearOS API provides that information so I just made an app that exposed it in a way users can visually understand.
Extremely simple app but, I can now say I am familiar with Kotlin and WearOS.
As of writing this the app has been installed 570 times.
