Build 1.1

Original source code packaged up into an .ipa file. Note that I am not aware of any way to sideload apps to the Apple Watch via an ipa package.

Build 1.1 via TestFlight

TestFlight link is open, though spots are limited due to Apple's restrictions. Remember that this build is temporary and may disappear at any time so you're better off using the source code directly if you can.
