Timegrapher X

I am quite impressed with this app so far. In a quiet room I was able to get some solid data and improve the accuracy of my Seiko from -7s/d to +3s/d. I’d be really interested to compare date from a standalone time grapher, but alas I do not have access. I also really appreciate that this developer collects zero data, and has one of the best privacy policy’s I’ve ever read. A breath of fresh air

$30 for a useless app. Stopped work completely after iOS 18.1 update. Never worked with a wired headset in any iOS. Inaccurate.

I’ve tried most of the common watch timers for the iPhone and this one is by far the best. If you want a real tool to do watch regulation, this is the one to get. (P.S. I never write iPhone app reviews.)

Works exactly as it is described and is extremely accurate. Was easily able to regulate an ETA 2892 (Omega Seamaster 300) quickly and reliably.

Extremely good product. Been running it on my iPad with the watch and microphone in a drawer to reduce noise. Just wished it would stretch on the iPad display.

I have stopped using my other timegrapher completely. This does everything I need to adjust and regulate my watches. I use it with the Apple Earbuds and ot works great.

Finally a time graph that works!!! I couldn’t be more pleased with this app. Worth every penny. I’ve been a watchmaker for 35 years and this might be the handiest tool to come along in decades.

Well worth the cost. I was immediately able to regulate an NH36 movement (Seiko) that I got in a watch from AliExpress. When received the watch was measured at running +46 seconds a day, lol. It’s now running +-5 seconds a day. Also, the developer has posted a very good video on YouTube on how to use the app.

I was originally annoyed at the pricing model and still believe the developer should be more clear. The Pro version is $60. But that’s where the annoyance stops. This app is rock solid and extremely accurate. A quiet room is all that’s required… and it can even tolerate a little background noise. Note to Developer: although the app still runs flawlessly, it’d be great to feel a little love from time to time to let us know you’re still around :)

I just got a used older automatic watch to learn how to work on watches as a hobby. As is, it was running 5 minutes ahead every day. I needed something to adjust it, but didn’t want to spend the $200 or so for the standalone equipment, or even $50’ish for a Chinese knockoff. After watching some “how-to’s” on You Tube, I got this app and got my unopened and almost forgotten Apple earbuds out of the iPhone box. The app picked up a weak signal right away, and had a strong signal after I got the microphone into a good position. It automatically determined my watch settings. As I worked, the graph display immediately told me if I went the wrong way or too far. In 5 or 10 minutes I got the errors down to below 5 seconds a day, mind you, a beginner working on such a small scale for the first time, with the final adjustments essentially too small for me to see. A day later the watch is still running within a few seconds of my iPhone clock. Now I can buy a few more watches to fix up, wear, and keep adjusted, in no small part because of the low cost of this app. Very, very cool… and fun too… Thank you for this app.
