It is a very good and useful app,indeed. I can confirm it is very accurate. However,the silent room is a must for achieving the best possible results. One friendly piece of advice to the developers... please change the interface of the app or add the option to personalize the screen with the different styles. Also, I think the FULL SCREEN interface is mandatory. We all use modern phones, and the current interface is only half the screen. I hope you understand. Regards, Alexander.

This app works surprisingly well. I got it to just give me an idea about how my watches were running on the fly. I have a proper time grapher, and this app goes toe to toe with it. It's very accurate. My only issue is that it sometimes can't get a reading on a watch with a thick case, like a heavy diver. I suppose that's due to the sensitivity of the mic, not the app itself. Overall, I'm very pleased.

This is a very useful app. With the latest revision, the only advantage of a timegrapher is the convenience of the clamp. You need to use it in a quiet room for best results. Some watches "read" better through the crystal or the case back, so try both. And setting the watch on wood is better than on something sound absorbing. Highly recommend.
