Ratings and reviews

Great app but seems to have a major bug. Very easy to use and clean interface but the app is rounding timings to the nearest whole second and only shows ".00" instead of the actual decimal while the video demo and screenshots on the Play store show actual decimals. If this bug is not fixed it would unfortunately be a fatal flaw for an accuracy obsessed watch nerd like me.

26 Feb 23- Full paid version, which is $$$ for what it is. This app is one of the better ones avaliable. Easy to use and no need to wait for the seconds hand to get to zero, a great option which saves time for the end user. I'd recommend some different options with ordering of watches, such as listing the last time a watches accuracy was recorded, etc. As with all things, the app could always be better. Backup is easy to use, but only manual, not auto. I have not seen an update yet.

The watch is great. What I don't like is that after upgraded to remove the ads, which was removed, I have to pay to have for advance settings that includes color. After the second upgrade the app remained the same, no additional colors, no dark mode, just the same. Whatever you sell, if you are paid what you ask you have to deliver.
