What's New in Movement

2.0

January 13, 2020

Our top requested feature is here! You can now manually split or join runs. When you reset your watch, our AI attempts to detect that and start a new trendline for you. However, even though it’s 2020, the AI sometimes gets it wrong. If that happens, not to worry, you can now force-press or long-tap on a point to reveal a “Split Here” or “Do Not Split Here” button. You get to lord over the AI. For now. Thank you for using Movement. If you like the app and want to see more updates like this, please help spread the word!

Best watch movement tracker around!

Tried several apps over the years, but this the simplest and easiest to use. Love not having to sign up for an email account to use.

Practical watch setting tool

This is a simple effective clock for setting watches. I particularly appreciate the tactile bump/rumble at each second, which helps makes accurate setting easy without relying on audible noises.

There is also a watch accuracy tracking function, which is probably sufficient for identifying when a watch needs servicing. It relies on manually inputs so isn’t a very precise way of tracking the actual deviation of a watch, but good enough to track watch performance.

Finally, it’s neat to have a simple analog clock set to internet-atomic time.

Great at first - not great over time

This app seems amazing at first and it does the job really really well. However over time the problems start to emerge. They are relatively easy to fix as they are mostly UI problems.

Problem 1) If you have lots of watches then it is tricky to see the accuracy score for all of the watches in one list without lots of scrolling. It is not possible to reorder the watches either.

Problem 2) This is the biggest issue. I have been tracking one watch now for about six months. The scale of the time measurement points compresses over time so my 6 months of twice a week time checks have now compressed so much that the accuracy scores are all written over the top of each other and are unreadable - this is the historic scores as well as the most up to date. I could delete the old ones but it is good to see trends.

This app is so nearly perfect but these two problems (particularly #2) really mar the usability.

Fantastic App

This is a very intuitive and nicely designed app. It has been built with a lot of thought and does exactly what it says on the tin. It tracks your watch accuracy. If there could be one possible improvement, it would be for Grand Seiko owners - who I’m sure would appreciate an extra decimal place - just to make it interesting below +/- 0.01 secs per day.

Perfect!

This is the app I’ve been looking for. Simple, straightforward, looks great, works well. Set your watches according to the atomic clock in one screen, measure their accuracy over time in the other. Leaving a review as this should be higher up in the App Store. Thank you!
