Enough

Selectively displays important weather information.

Displays time to upcoming event, if less than 60 minutes.

Displays heart rate if above 90, otherwise displays battery.

Top symbol is media play-pause. Left and right dots are reset and stop/start for the stopwatch, respectively. Tap the time to set a timer.

To get air quality and chance of rain, install the SimpleWeather app on your watch, and set complication 1 to "Air Quality" and complication 2 to "Chance". Only supports Fahrenheit, unfortunately. In Celsius, it doesnt correctly decide which of the high and low is more interesting and always displays the low.
