Comments on ChronoLog Watch Accuracy Meter for Android
★★★★☆Pablo Mendizábal Mondragón· Sep 3, 2025
Nice app with some room for improvement. UI is nice, intuitive and clean, graphs are quite nice as well. The first measurements usually have very big offsets that are clearly wrong (anywhere from 5 to 50 seconds off) even though I just synced watch time and app time, and I have to try 2-3 times for an accurate offset. Which makes me doubt the accuracy of the later measurements sometimes. It would also be nice to be able to have notes per run. e.g. "1st run after adjustment", etc.

Great App for watch and clock enthusiasts. User-friendly and detailed enough to give very accurate graphs over time. User can also save his/her collection data including the watch photos. That makes it a piece of cake to pick the right watch in case the collection is big. Tyler, the App creator and administrator, is eager to help and provide advice. Full Kudos. Scooping tip. He's working in improving the app by adding microphone 🎤 measurement option and new charts. Fully recommended. 👌👍

Pretty good for free app that look and feel very professional. It does allow like 1 watch with 3 logs. Continue testing if like for sure to buy the pro unlocked version.

Doesn't check accuracy, just a log of relative time
★☆☆☆☆Gary Novosielski· Aug 1, 2026
Call me old-fashioned, but I can't get this thing to do a measurement. Is there any documentation anywhere?
★☆☆☆☆Jonathan Birge· Nov 18, 2025
Broken in many ways. The import doesn't work, nor does email the developer. Wasted my money on this after using the iOS version.
★☆☆☆☆R V· May 15, 2026
It stole my time by stating that I have to pay after the 5th time (day in my case) when I came back to measured accuracy.
★☆☆☆☆Marchell Du Plessis· Jul 10, 2026
doesn't work right, only 3 free measures by the way. Would rate 0 stars if I could a waste of time
