ChronoLog • Watch Accuracy

I have tried a few apps that aid in tracking your watch’s accuracy, and this one is definitely one of the better ones. First of all, it’s easy to take a measurement - due to its “smart prediction” and big (easy to hit when you’re staring at your watch) button. It also has a clock section that helps when setting the time on a watch, as well as tracking other time zones, GMT, etc. Plus, it has a refined UI and a reasonable price, so it’s been pretty useful!

this is my first review on the app store in YEARS. i really can’t remember the last one i did. for the price of entry for this app you get full forever access to catalog your watches with their pertinent data, purchase date, price paid, etc. and with very easily tracking of how slow or fast your watches are running with historical data to see trends over time, as well as the perfect analog clock WITH haptic feedback per second to set your watch right on time very easily. app is attractive and minimalistic to a degree with only the important info displayed. this is the perfect app for someone wanting to casually keep up with watch accuracy.

I just recently got into automatic/mechanical watches, and was looking for a way to measure the accuracy of my timepieces. ChronoLog is straightforward, very easy to use and intuitive. I love that the offset, change and rate are all displayed for you, as well as the graphs that help you visualize the changes. Adding a measurement and/or point is also very straightforward. The ability to personalize each watch with a picture and details of the brand, model, purchase date and purchase price are also nice. When you’ve got multiple watches entered into the app, it really gives you a sense of collection whenever you open ChronoLog. Overall, I think ChronoLog is a solid app for watch enthusiasts.
