Excellent for Watch Enthusiasts

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.

I was a little skeptical when I fist came upon this application! First let me say I have 8 Watches. Ranging from expensive to the more average affordable prices. This app. Not only works extremely well, it is also a lot of FUN!!After mastering the how to’s and the do’s and don’t’s, I find it highly enjoyable. You can track anything with a sweep or second hand!I’ve been surprised how accurate some on my watches are and some not so much. I highly recommend this for anyone owning a watch.

Great App, less features every update

Had this for about four months, love how simple it is to use. However, when I first downloaded the app, I had four watches, two timing runs per, and 5 measures in each run. Over the last few updates, I can only have 2 watches now, 1 timing run each, and only 4 measurements. One feature is removed per update so I didn’t really even notice until today, but it is disappointing. Would love to support the developer, but I feel like I’m being squeezed and now less likely to.If you get the pro version, I’m sure this app is one of the best. Not sure I’ll test that theory

Thanks for using my app and taking the time to leave this feedback! It sounds like for four months you've loved using the app I've worked very hard on and you thought it was great, I'm happy to hear you got so much value from it! I've been able to polish this app and make it such a good experience due to folks valuing my work enough to support it with a one time purchase, about the cost of a cup of coffee. I'm sorry that after four months of use, my work didn't earn that support, or even a positive review, from you.

The greatest app for watch tracking

This is a robust and reliable app to track watch accuracy over time. The interface is intuitive and the representation is great, I can see the evolution of the watch accuracy in many ways: rate in sec/day or how much it got offset by the end of the run. Handy to make sure the watch hasn’t been magnetized or started malfunctioning (indicating a need for service). The developer is very kind and responsive. Thank you Tyler!

Appreciate the review! And the detailed bug reports, makes em easy to fix :)
