Ratings and reviews

seems to work just as I hoped, no surprises. I wasn't sure from the in-app explanation, but the "Premium" upgrade in fact turned off the advertising, whew. Watch setting isn't all that exotic, though it's nice that this references both your device time and NTP, and tells you the difference, and does the minute approaching beep thing. But the trick of logging watch accuracy over time is fun, and seems well done.

Nice app. Does a great job of tracking the watch accuracy. Would've given the app 5 stars if there was some way to create a note with each accuracy check. (Ex: Noting the overnight position of watch - flat, on its side, upside down, etc. As position affects accuracy.)

Great little clock app especially when you need perfectly accurate time. I find it great at daylight savings to use as the master clock to set all the others against. The toggleable on-the-minute pips are excellent to provide an audible signal so you can concentrate on the clock you're resetting in front of you, and use this app "hands free" Simple, clean interface, an excellent example of design done right.
