## What is Movement?

The best companion app for your mechanical watch.


Features

• Set your watch precisely with a full-screen atomic clock.
• Track your watches’ accuracy over time with beautiful charts. Trend lines tell you how your watch is performing and let you know when it’s time for service.


Atomic Clock

The “Atomic Clock” tab is a precise clock you can use to set your mechanical watch to the second.


Watches

On the “Watches” tab, add and name each of the watches you want to track. Tap “Add Point” to add a measurement. Wait until your watch’s hands match what’s shown on the screen, then tap the screen. This will add a point to the chart, recording if your watch was ahead or behind, and by how much. Repeat this over time and you will start to see trend lines with an estimate of your watch’s accuracy.

If your watch gains or loses 3s/day or less... congratulations! You have a chronometer-quality piece. If your watch gains or loses more than 60s/day, it might be in need of service.

When adding a measurement, if your watch is ahead of the time shown on the screen, or significantly behind, you can adjust the target time to get closer. Use the -5 and +5 buttons until the hands are slightly ahead compared to your watch, then wait for your watch to catch up, and tap.


Tips

• When you add a point, the hands on the screen automatically jump ahead by 5 seconds. This is so you can add a new point 5 seconds later. Do this a few times in a row to increase the accuracy of your measurements.
• When you reset your watch, our AI will attempt 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, 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.
• To remove a point, force-press or long-tap on it to bring up a delete button.
• Multiple points taken within 30 seconds of each other will cluster together and their average will count as a single measurement. Long-tap on a cluster to see and edit the individual points within.
• If you have iCloud enabled, you can find raw data, with all your measurements, in your iCloud Drive. The data is in the standard CSV format, supported by Excel, Numbers, Google Sheets, and many other apps.

### 5/5 — Best watch movement tracker around!

*2021-12-03*

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.

### 5/5 — Practical watch setting tool

*2021-10-18*

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.

### 3/5 — Great at first - not great over time

*2021-06-08, version 2.0*

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.

### 5/5 — Fantastic App

*2021-02-13, version 2.0*

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.

### 5/5 — Perfect!

*2020-12-08, version 2.0*

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!

### 4/5 — Use it all the time

*2020-10-28*

I use this app daily to sync my watch.  Only suggestion that I have for improvement would be to either remove the “3” from the clock face or provide a wider separation between the date and the “3” so that the numbers do not “merge” together when reading the time.  Fantastic app.    Thanks!

### 5/5 — Good - faster adjustment needed

*2020-09-21*

Great App, great design and accomplishes the purpose. When trying to monitor old watches can take a long time to adjust the time to match your not greatly adjusted watch. A faster adjustment setting needs to be created (a button for 5seconds forward and backwards and a minute forward and backwards for example).

### 5/5 — Well worth the purchase

*2020-09-20, version 2.0*

The large clock face with sweeping hand makes setting and tracking your automatic watch a dream. Would recommend to anyone who like to keep precise time on their watch and likes to track. Like one review said, “a bit of a risk on the purchase but well worth it.”

### 5/5 — Best design, lots of opportunities

*2020-09-05*

In the space of trackers for mechanical watches, this is the only app I’ve found that makes an attempt to be designed well. 

The clock is great, the measurement screen is fantastic. The graph needs work. The per day deviations overlap each other and become unreadable. The AI recognizes resets and separates days, and then doesn’t the next moment. There’s no affordance to split days manually, making discovery of that feature hard. Not sure what happens if I continue tracking because the graph does not seem to be designed beyond a few days of space. 

Overall, I enjoy using it and it has the potential to become the one and only watch tracking app out there, the reference point for all. I’d love to see it get there.

### 5/5 — Excellent

*2020-03-16, version 2.0*

Took a risk on this app as the free app I have been using hasn’t been updated for years, and it’s more and more glitchy. And I’m so glad I did. Lovely clean interface, easy to use, and if you make a mistake it has an undo. I can see this being a staple on my home screen for some time.
