Twixt Time

Unfortunately this piece of software, apart from being complex in using, just doesn't work - time accuracy jumps from -12h to 10mins to +12h on a proper working watches.

After a full service center overhaul of my Omega Seamaster I decided to use Twixt to check the accuracy. Even though my watch had just been serviced Twixt measured that it was gaining just over 6 seconds per day (the threshold for chronometers). I took this info to the service center and they were able to get the gain down to about 1.3 seconds per day. Without Twixt I wouldn't have known my watch was out of spec and would have just accepted poorer accuracy than necessary. The app itself is clean and easy to use. I didn't expect it from just photographs of the watch face but the accuracy is impressive: it matched the Omega service center's measurement exactly.

Kinda works... Great idea that needs to be fine tuned.

It works as advertised but It is finicky to use and not very precise. Hard to select the exact spot to mark the hands and the middle.

As per the Worn and Wound review, it's not perfect/done. Right now it's not worth it. First, it definitely needs a 10-minute spread for marking noon. Tons of watches don't have minute hash marks, or use numerals instead of an indice at 12. Second, performance is baaaad. It runs very, very slowly - and when you're trying to precisely line up hands and pivots, having a very unresponsive app is not good. Maybe ditch the cute lens effects on the zoom to speed things up, they aren't needed. It has potential, but wait until they make it good - and let's hope they put more effort into fixing it than they did Kello.

You need to map the positions of the hands on separate pictures so it computes the time difference between the watch and the iPhone. It's not a video analysis like it was sound analysis with the other app. Useless and expensive.

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!

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.

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!

Too expensive for not getting these basic features!
