Very handy app
As far as tracking the accuracy of your watch, I really like the ‘time was set’ option so that you don’t have to start a new timing run just because you update the time of the watch.
As for setting the time, I really like the atomic clock with the loud ticks and beep at the top of the minute, and find it to be a very thoughtful feature.
I recently regulated my Seiko automatic watch using TG, and it's very satisfying to be able to see the fruits of my effort using this app.
Big thanks to the developer.
