Twixt Time helps track the longterm accuracy of watches and clocks, by collecting & analyzing precisely timed snapshots of their dials.
Use Twixt Time to take a picture of the dial of an analog clock or watch. Each picture captures the exact time displayed on the dial. Twixt also notes the precise instant that the each snapshot was taken, by communicating with highly accurate NTP timeservers on the Internet.
A new snapshot of each timepiece can be added everyday. Using the information from 2 or more snapshots of the same timepiece, Twixt will calculate and show you how precisely the watch or clock is keeping time.
Twixt tracks the most recent rate, overall average rate, and cumulative gain or loss for each timepiece.
Supported dial configurations:
* Hour & minute hands with a central seconds hand
* Hour & minute hands with seconds displayed in a subdial
* Hour & minute hands only
Does Twixt Time work with GMT watches?
Yes. Twixt Time does not need to track the 24 hour hand of GMT watches to measure their precision. It is only necessary to track the hour, minute, and second hands. For GMT watches with central seconds, select the "central seconds" layout. For GMT watches with an offset or subdial seconds hand, select the "subdial seconds" layout. Twixt Time automatically monitors timezone changes based on the timezone setting of the iPhone or iPod touch.
Does Twixt Time work with chronograph watches?
Yes. The chronograph functions of a watch do not need to be measured to track the precision of the watch. Twixt Time tracks the precision of chronographs, as well as watches with other complications, in the exact same way that it tracks the precision of a normal, time-only watch. If the central seconds hand can be stopped and reset with the chronograph function, select the "subdial seconds" layout to track the small seconds hand with Twixt Time. If the central seconds hand continues to move when the chronograph is stopped, but the small seconds hand stops, select the "central seconds" layout to track the central seconds hand with Twixt Time. Most chronographs will use a subdial seconds layout.
Does Twixt Time work with watches that have an offset seconds hand?
Yes. For watches with a second hand that is not concentric with the hour and minute hands, select the "subdial seconds" layout.
Does Twixt Time work with quartz watches and clocks? Or other watches and clocks that are powered by batteries?
Yes. Twixt Time works with battery powered watches and clocks that display the time with an hour, minute, and/or second hand. It does not work with watches or clocks that only display the time digitally.

Is Twixt Time legit?
🤔 The Twixt Time app's quality is mixed. Some users are satisfied, while others report issues. Consider reading individual reviews for more context.
Da ich die Software praktisch täglich nutze, kann ich nur Positives sagen. Neben einer Zeitwaage, die mir ja nur den technischen Status-Quo gibt, hilft mir dieses Programm, eben das Gangverhalten in der alltäglichen Situation zu dokumentieren....
Crashes very often
App crashes 9 out 10 times I try to use it. Updating did not solve as well as reinstalling.
Questionable Results if you manage to get them :no my watch is not running 2 hours wrong that I can tell...
Good idea so I hope things get fixed
Die Richtung stimmt!
Eine App, welche die Ganggenauigkeit meiner Uhren dokumentiert, war schon immer ein Traum von mir. Die Idee, dies über einen Abgleich von Bildern zu lösen, ist recht pfiffig. Leider ist diese Art sehr ungenau und funktioniert nicht wirklich präzise und zuverlässig. Fokussierung beim erstellen der Bilder geht auch nicht immer reibungslos. Dies, sowie die Usability lassen mich nur eine eingeschränkte Empfehlung geben. Freue mich schon auf kommende Updates.
Good concept and implementation...
...but no support for 24 hours dials.
Update: option to change the name of the watch afterwards would be also great. A name was written wrong and I don't want to delete the measured values just because of that.
Ungenau
Am ersten Tag waren es + 3min. Am 2ten -3,2min Abweichung! Für mich ergibt des kein Sinn bei einer frisch Revidierten Breitling.
Sehr gute App...
…um die Gangabweichungen zu erfassen. Nutze die App seit der ersten Minute und bin rundum zufrieden. Das Handling ist mit dem Update besser geworden! Das einzigste das nach wie vor vorhanden ist, ist das die Kamera ab und zu nicht sofort Bilder liefert. In diesem Fall muss die Uhr erneut ausgewählt werden, danach läuft alles.
Ich kann die App empfehlen.
Betrug!
Omega aqua terra (8500) läuft mit +1s/5days. App sagt -18s/day. Eine Frechheit hier 4,99€ zu verlangen!
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.
Great App for Watch People
I’ve been using this app for several years, and it just works. Allows me to keep track of the timekeeping for my watches in a simple yet effective way. Thank you!
