I'll look into it. I think that this will ultimately be a suite of apps by the time we are done.

Great idea. I'm on it. Thanks! I made great progress last night. I hope to have the 2-up timing done today

Probably not too hard to do as an arduino project.
I've been working on that too as a research effort. I'm learning the Bluetooth framework. I can get raw Hex/Binary data from a speed/cadence sensor that I'm playing with, but I'm stuck on how to translate that into base 10. I'm getting unexpected errors in Swift (not sure if it's my fault or that the framework isn't fully baked...probably the former). The harder part will be setting up a tape switch, arduino, etc... But all of that is definitely on my radar.

The Bluetooth LE range is less than 100M. I think the bugger will be BT connecting, disconnecting, or not connecting when it's in and out of range.

WOW. That thought has never occurred to me. I need to research this.

This is why I bought a BT speed/cadence sensor to work on making a BT thumb switch system. This will take a lot longer to make than some of the calculating, timing, logging features mentioned above.
