Edit: Changed to 5 stars since the developer corrected my misunderstanding of how the app works. Now it is pretty much perfect!! Thanks~ Old Review: The app does everything I could want EXCEPT one critical flaw... you cannot edit measurements to remove or update an incorrect log. If you accidentally enter something wrong or realize you logged under the wrong watch, you lose your entire progress and have to delete the watch and start from scratch. even if you've been tracking it for days/weeks.

Thank you for your feedback. You can remove wrong entry by swiping left of that entry. Trashcan icon appears and you can delete the record.

I love this app but I keep noticing a concerning issue. The timing appears to be off. I am clocking my watch at -14s on a given day, and the math shows that from the current time of my watch compared to the time shown on the clock when the button is hit and it often looks to be off by 1 second. Idk if this is a result of milliseconds not showing in the calculation, but it doesn't feel like the tracking is always accurate. Hope this can be addressed / fixed!

Great app. I live right on the border between Eastern and Central time. Depending on where I'm located on the farm and which cell tower I'm pinging, my phone will jump back and forth an hour. That makes for a confusing day. So we keep our phones permanently set to Central time. By not pinging a tower and getting constant time updates the phone drifts forward. Over the course of a couple of months it will be as much as 3 minutes ahead. I know this because of the Atomic Clock app. Edited

Enjoying the application, it's a great place to keep track of my watches, and their accuracy. It would be nice to have the ability to configure your own NTP server(s) as well as just choosing from the popular list. Moonphase would be a great addition, too for setting watches with that complication.

this is a simple and efficient app. It gives you two choices for atomic time, to compare you watch too. I'm trying to time an Invicta Grand Diver, and these things are either right on or like mine, right off! LOL I've been fooling with it for a week now, and it jumps for me from a minute fast per day, to a minute slow per day. I'm right at a point where it can only be moved a nanometer to get it where I need it + or -3 to 5 seconds per day. Couldn't possibly do it without the help with this app Edited
