Works great

Better than any of the others. Unique way of capturing time makes this app a cut above.

This app saved me a huge headache!

I have been using Twixt for nearly a decade and recently took my watch in for a service (which thanks to Twixt was showing a slow degradation in performance over a couple of years). When I got the repaired watch back from the watchmaker something looked amiss but I couldn't tell what it was. Thanks to Twixt I was able to see photos of the watch before the service and immediately it was clear that the watchmaker had replaced the hands with slightly different ones. I never would have been able to know this without a long history of photos of the watch. It was also very easy to show the watchmaker the error since there wasn't much to argue with about the clear evidence of the incorrect hands. I was able to share screen shots with the watchmaker to show the change - an idea to improve the app would be an ability to export/import timelines. Otherwise the app has been matured to perfection as the developer has made continuous improvements to it over the years. Thanks!

Tedious, inaccurate

I didn't think it was possible for them to make an app worse than Kello, but they did. This is very tedious to use and very inccurate. You have to take a photo of your watch and manually locate the cetner, 12 o'clock, hour, minute and second hands on the screen...repeat to get a reading. After all that, it said a mechanical watch of mine was runnning at +12 minutes per day---which is not even in the ballpark. A real timegrapher shows it is running ~+4 seconds. Don't bother with this one.

Response from developer

Hi CAG_1337, We have added a lot of features since version 1.02 to assist with the positioning of the hands and would love to hear what you think of the app today. You may also find it helpful to note that it is important to capture successive Snapshots at least 24 hours apart. Snapshots that are taken less than a day apart will multiply any errors due to parallax, beat rate, and/or hand position. The purpose of the Timeline lock, which can be enabled or disabled in Settings, is to guard against such errors. For the most accurate results, it is best to wait 24 hours before adding a new Snapshot to a Timeline. If you have any questions or need further assistance, please feel most welcome to reach out via email, at twixt@coldflower.com UPDATE: Thank you for taking the time to repost the review that you wrote back in 2013. I can only begin to imagine how frustrated you must feel. I would love to help you get the most out of Twixt Time and would be happy to investigate why you encountered the results that you did. As before, please feel most welcome to reach out to twixt@coldflower.com for support. Mention that you are CAG_1337 and I will attend to you personally, so that you do not need to articulate again anything that you have already here. Thank you for your passion for horology and precision. I admire it.

FAQ

What does Twixt Time do?

Twixt Time is an application designed to track the long-term accuracy of watches and clocks. It achieves this by allowing users to take precisely timed snapshots of their timepiece's dial. The app then analyzes this data against highly accurate internet time servers to calculate the rate and cumulative gain or loss of the timepiece.

How does Twixt Time track accuracy?

You take a picture of your watch or clock's dial, and the app records the exact time the photo was taken using internet time servers. By taking multiple snapshots over time, the app can calculate how precisely your timepiece is keeping time, showing its recent rate, overall average rate, and cumulative gain or loss.

Is Twixt Time free to use?

Yes, based on the provided information, Twixt Time is a free application. It does not have in-app purchases or advertisements, indicating a completely free user experience.

What types of watches and clocks are supported?

The app supports watches and clocks with hour, minute, and/or second hands, including those with central seconds, subdial seconds, or no seconds hand. It is compatible with GMT watches, chronograph watches, and battery-powered (quartz) watches and clocks that display time visually, but not those that only show digital readouts.

Can Twixt Time be used for GMT or chronograph watches?

Yes, Twixt Time is designed to work with GMT and chronograph watches. For GMT watches, it only needs to track the hour, minute, and second hands, and it automatically monitors timezone changes. For chronographs, the app tracks the timekeeping precision regardless of the chronograph functions, using specific layout selections based on how the seconds hand behaves.
