Lots of nonsense emails sent to you when you are forced to sign up for an account. I don't need all this unnecessary stuff. There are better apps out there that's does a simple function. I will use an excel spread sheet and graph if I have to. Simple things made complicated in this app. Uninstalling it.

Makes no sense, as it simply forces you to compare your own watch to network time servers over long periods of time. A real watch analysis tool (like Tickoprint) 'reads' the beat rate via microphone, measures beat errors down to microseconds. Only THEN an accurate and fast measurement of timing errors can be seen and quickly adjusted, by regulating the balancer. This app is usesless: anyone can compare any watch against radio time signals (TV, GPS, atomic clock receivers) at any time and anywhere - without an 'app'!

It appears the time sync with the aromic clock is not accurate or has a lag. this causes huge swings in calculated "accuracy" of watches. My quartz was running +1.1 seconds which was probably close to correct, the next day it says its 102 seconds fast. I rechecked it with the atomic clock on the internet and it was spot on. If it was consistent this would be a great app, unfortunately, its not worth it if it cannot do its job well.
