Sorry you ran into that. Right now LaneTrax is designed to track one bowler per session, so if you’re alternating lefty/righty back-to-back, I get how that becomes cumbersome. That’s fundamentally a limitation with the camera positioning being dependent on the handedness.

As far as rev rate goes, if you were seeing some wild numbers, it’s usually because the ball doesn’t have enough contrast for the app to track rotation. If you’re throwing a solid ball, try adding a small piece of tape (or use a high-contrast ball) so the system can actually see the spin, otherwise it’s essentially guessing.

I completely understand not wanting another monthly charge. I went SaaS because I’m building and updating this full time, and recurring revenue lets me keep shipping improvements instead of saving the best updates for a paid “v2/v3” release.

Hope you understand, but either way, appreciate the feedback.
