Description

Watch Tracker is a revolutionary app for tracking the accuracy of a wristwatch. It's dramatically easier and more accurate than any previous method.

Just tap a button when the time on your watch matches the time displayed by the app, and Watch Tracker does the rest. It synchronizes with an atomic clock, measures and records the difference, and displays graphs of all the data points you've recorded.

- Uses best-fit analysis to accurately calculate how many seconds your watch gains or loses per day
- Displays graphs of rates and variance
- Can track multiple watches simultaneously
- Saves data in CSV files that can be opened with any spreadsheet software

Watch Tracker is made by the developer of tChess (the chess app that was featured in Apple's "Learn" commercial for the iPad) and Learn Chess (the Apple Staff Favorite e-book).

So far so good

So far am really liking the app over what I was using, I have a Timegrapher to check various positions of my watches so I can regulate for best accuracy but this app gives you a good bit of info on accuracy while wearing and resting positions

There is a small amount of human error involved as you have to tap the screen at a certain point in time and you could be off by a guess of +/- .5 secs as I don’t believe it’s possible for you to tap at that exact moment in time but none the less it gives you some very good useful info and some of the key features are you can track over a long period of time.

The app developer is very helpful in answering questions and taking suggestions which is great, there are a few changes I would like to see but if they never came I would still use the great little app

Very erratic results

Edit June 13, 2020
I ended up to I sticking with this app and I’m glad I did. I think the problems I had earlier somehow had to do with what happens when the minute hand moves past the minute marker but the seconds are not there yet. Hard to explain. Now I let the app decide the minute and make the measurement but the second hand and that works. It has a lot of nice features that the others I’ve used done, like the comments.

Original review: I’ve been trying out this for a month or so and either all of my watches are extremely erratic, or this app doesn’t work. I do a timing on a watch for days or even longer, and get a nearly straight line for that run. Then I do another timing run, and I get a zig zag line, flunctuating by double or triple the amount of the first. Sometimes, it’s vice versa. So after more than a month, I have no clue as to how my watches are running. I recently heard in a watch channel, about another app, so it’s time to delete this one and give the other one a try.

Solid App

Well-designed, just like my watch :)

This app omits questionable features such as ‘magnetism detection’ or calculations made from audio recordings of your watch.

Instead, I would call this app a (very user-friendly) specialized calculator. The time source it synchronizes with is quite good.

Although a spreadsheet is capable of doing the same math, this app is worth the money (in my opinion) because of a specific feature: a button that will instantly record atomic time when pressed. Pressing this button also simultaneously records a predetermined hh:mm:ss. The user plugs in some time in the near future and presses the button when their watch reaches that time.

Therefore, each data point contains two pieces of information from that instant: standard time and your watch’s time. This operation would be difficult to perform without a specialized program. Another method might be to use a high-speed camera that takes a picture of the watch next to some time standard. However, processing this data would require more time as the watch reading would need to be interpreted from a picture. I like this app because you can press a button and then bam, it’s done and it’s even calculated averages including all your previous data points :) very well done app
