App review: WatchCheck

Rate this Entry
I'm a bit obsessed with accuracy in my watches, not necessarily in them being very accurate (I appreciate it when they are, but wouldn't necessarily pay for them to be regulated), but in knowing how accurate they are. I used to use a very basic method of checking and recording accuracy - timing them against my solar atomic G-Shock at the same time each day and then making a note of the deviation in Evernote or Google Keep.
A couple of days ago I thought I'd re-explore the options on the Google Play store and ended up trying one called WatchCheck

I'm really impressed with it so far, the interface design isn't perfect but it does the job, and the actual functionality is spot on.
As you'd expect, it allows you to store profiles for multiple watches and track the accuracy of them over time.

I'd looked at apps before that took a photo of your watch face but found them a bit hit or miss.
WatchCheck has a simpler approach but one that works well. When you want to time a watch, you set the time against which you want to compare it and then hit a button on the screen when your watch gets to that time - hard to explain, but hopefully the screenshot below makes sense of it.

Once you've done that, you can then add data about the position and temperature of the watch at the point of timing. You can also indicate that you're starting a new timing period if you've reset the time on the watch.

The app then does everything else, giving you an average daily variance and recording the stats, including a breakdown of the performance in different conditions.

It seems to be related in some way to a blog called 17jewels.info, and within the menu there is a link to view articles on that site, but that's as far as the advertising goes, aside from that it's free to use and ad-free. You can also set a daily reminder to prompt you to time your watches and backup the data you've recorded to the SD card in your phone.

I'd definitely recommend it if you're looking for something to track accuracy.

    While I don't think I'll be tracking the accuracy of my watches (daily wear being a G-Shock Rangeman) I can appreciate the setup you have there. Thank you for sharing.

    I'm a timing nut too but I use Watch Tracker for iPhone 5 https://itunes.apple.com/us/app/watc...610666926?mt=8

    It seems to operate on the same principle as your app (you hit a button to enter the time of your watch which is then compared to the atomic clock on the internet), producing a graph for each watch. But it does not allow you to enter information the position and temperature of the watch, so these can not be tracked independently.
