Air Lookout: Apple WatchOS Complications (Graphic Rectangular)

The graphic rectangular complication on watchOS is pretty interesting. It is basically just a large image to dynamically draw whatever with Core Graphics.

For Air Lookout, I decided to draw a chart that shows Air Quality Index, pollutant concentrations, and Air Quality Index color for the past twelve hours.

Air Lookout now supports every available 3rd party complication on Apple watchOS. Most of them have a dynamic sparkline graph or trend arrow.

I wrote a little bit about designing and building them.

If you like what you see, you can download Air Lookout on the iOS App Store.
