Functionality is easy to navigate. Logging is right on. However, I really wish author would fix the average rate and offset calculations. They are just wrong. I manually calculate them myself from the nicely recorded and presented data. Minor easy to fix bug that would make this app perfect. ### 1/5 — nice app. doesn’t work *2020-07-13* i bought this app to measure how fast or slow my watch is. my first measurement was 13 seconds fast vs the atomic clock. my second measurement, 2 days later, was 20 seconds fast vs the atomic clock. by my estimate, +7s over 2 days means my watch gains 3.5s/day on average. the app, somehow, calculated that my watch is gaining 11s/day. i really can’t understand what happened here. my watch doesn’t have a hacking second, maybe that’s causing the problem? does the app not know how to deal with an initial measurement that’s not exactly accurate? very strange. a 5$ app failing at its only job is pretty unacceptable. ### 1/5 — Not at all useful *2020-05-17* Just wanted to make it clear this app is not for people who want to check accuracy using a attachment or headset microphone, this uses atomistic clock which is about as useful as using the clock built into your iPhone ### 4/5 — Pretty nice *2020-05-16* The sync button could be made a bit bigger for easier use while looking at your watch. And the launch screen should match the theme, light or dark. Currently it is always light even in dark mode. ## Frequently asked questions about Watchtimes ### How accurate is Watchtimes?
