Sounds cool, I’ll be a customer for sure. A nice function of the app would be to practice a particular shot multiple times and then get a spread score - how close to one desired spot are you hitting. You often hear about the importance of tip accuracy and consistency.
Also check out this video from a Tyler Styer interview (about 1 min - 2 min) where he says Johan would emphasize keeping the speed-to-spin ratio low, spinning the cue ball more but keeping the speed as low as possible.
If it could be associated with specific drills with specific goals, like low spread or speed to spin ratio, I think that would be most helpful. I think that was missing from the digicue.
Qi charging, I assume?
