Not working

Not working on iPhone 15pro. Zero stars. I tried Korg external mic and Apple headset. Mic setting in app goes back to internal; doesn’t see external mic. $30 down the drain.

Honestly pretty good

Better than I expected it to be. I used it with the headset it said to use, and I was able to get an accurate reading from my ST1901 which I knew was very off at about +13 s/d. I tried to use it with my Navitimer B01 and had a little trouble since it was so quiet and the signal was somewhat noisy, but it still did a decent job and gave me a good readout with very reasonable result. I’m pretty happy with my purchase as I don’t need incredible accuracy, but just want to be able to tell if my Navitimer should ever go in for service early. Thanks!

Trop cher

Pour une version final il faut payé le un deuxième fois 35€ dans l’application après l’avoir acheté.
( très dommage)

最好用的校表仪

真的,功能强大,十分精确,UI简洁,价格昂贵😄,但是物超所值!

要是能支持AirPods就更好了。

Something fishy here

Idk what these reviews are on about but this app doesn’t work very well. Can’t seem to get anything I try to regulate to be anything close to what it says. And even if I’m a sound proof studio room I couldn’t get it to get a stable accuracy. Just constant drifting. I would give it 1 star but maybe it’s just the new iPhone mics or something that’s no longer compatible (wild guess). Spend an extra hundred on a timegrapher.

FAQ

What does Timegrapher X do?

Timegrapher X analyzes the ticking sound of mechanical watches to measure their accuracy rate, beat error, and amplitude. It provides real-time waveform and detailed diagram displays, as well as long-term data logging for comprehensive analysis of watch performance.

What are the key features of Timegrapher X?

Key features include the ability to measure accuracy, beat error, and amplitude by analyzing the watch's ticking sound. It offers both an 'INSTANT' module for short-term analysis with real-time waveform and diagram displays, and a 'LONG TEST' module for long-term graphical data logging.

How much does Timegrapher X cost?

The app is free to download and use with basic features. Additional advanced features, such as saving and sharing branded PDF reports, exporting raw measurement data as a CSV file, and conducting longer-term measurements (up to 120 hours), are available through an in-app upgrade called Timegrapher X Pro.

What devices is Timegrapher X compatible with?

The app is optimized to work with Apple EarPods' headset microphone. For best results, it is recommended to press the headset microphone and the watch crown slightly together to improve signal strength and diagram quality.

What are common use cases for Timegrapher X?

Common use cases include hobbyists and professionals measuring the accuracy of their mechanical watches, diagnosing issues like beat error, and monitoring long-term performance drift. It's ideal for watch collectors, enthusiasts, and repairers seeking detailed insights into their timepieces.
