An outstanding tool for block starts!

Works well to monitor start technique and assess/compare each block release.

No updates. Bugs.

Purchased the updated version to use the camera interface. The app won’t even ask me to allow the use of the camera. So I went ahead into the privacy -> camera -> and start meter isn’t even listed in the app section. There is a bug here he hasn’t fixed in years. Hopefully the developer will get back to me or I will need my $$ back.

Awsome app. It would be cool to have a log of previous reaction times but still a great app.
