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.

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.

Amplitude missing
This app doesn’t show me the Amplitude, which is the only reason to get it really. The daily deviation in accuracy can be measured other (cheaper) ways just as good. I feel kind of scammed
Response from developer
Please see the docs, at least the Quick Start and Levels of Detail articles - stable amplitude readout requires strong signal. With any specific issue, please contact us at apps@onyx3.com and if still not happy with the app, request a refund. https://timegrapher.app/doc/
Works great!
App works great with the lightning dongle and 3.5mm headphones. Versus paying for a physical tool that will someday end up in a landfill, I appreciate using hardware I already own. Nice app, keep it up. 👍🏻
Great idea, not accurate
I have a watch that I've tracked over many days as running around 14 seconds fast per day. This app reads +3-4 seconds for the beat rate. So it's quite inaccurate.
Perfect and dead accurate
Would love to see some more love from the dev. It’s not cheap.
Excellent
Very good App that does the same as the typical hardware tools. I wanted to check and adjust my mechanical watch but didn’t want to buy an extra timegrapher hardware tool for more than 100 EUR
as it would only be occasionally used. Although the App recommends to use an Airpod as a microphone just slightly pushing the the crone of the watch to the phone’s microphone just worked for me. Reliable and even there was a hit of background noise in the room it measured very stable. 100% recommendation. Not a cheap app but well worth it.

Thanks for the review and glad you like the app! Note on using internal mic. A very close proximity to phone’s built-in speakers may magnetize the watch under test. Try to keep a distance of at least 2-3 cm between the watch and the device.
Easy to use!
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

Ottimo
App ottima e pratica per la misurazione della precisione di marcia dei segnatempo, molto utile per ottenere dei dati tempestivamente senza attrezzatura dedicata.
Does not work with iOS 18.1
$30 for a useless app. Stopped work completely after iOS 18.1 update. Never worked with a wired headset in any iOS. Inaccurate.
Impossible to use with new iPhones
It relies on the old wired headphones. The newer iPhones use wireless headphones and they don’t work when not in ears.
Great tool, near perfect if used well
I was skeptical, but this timegrapher app is well worth its price. Just make sure to use it in a reasonably silent place (some noise won’t disturb it, but will affect its sensitivity), and to use the microphone from wired headphones, so you can really put it in contact with the watch without risking to magnetize it. On many watches, the phone microphone from a couple for centimeters of distance will work well too in a silent room. Measurements are accurate and reproducible, and definitely enough to regulate a mechanical watch at home to a good precision, or to check the general health of a mechanism before you buy it. A real timegrapher will be even better, but this app does work surprisingly well.

Apparentemente non funziona…
Acquistata vista la recensione positiva ed il costo )che faceva presagire un prodotto ben fatto). Purtroppo nonostante svariati tentativi (con microfono, a filo e AirPods, e senza) l’app non sembra ricevere alcun segnale quindi nessuna risposta circa lo stato dell’orologio. Farò altre prove altrimenti chiuderò un rimborso della somma (alta) spesa.

Best of all the watch timers for regulation
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.)
Great app
Works exactly as it is described and is extremely accurate. Was easily able to regulate an ETA 2892 (Omega Seamaster 300) quickly and reliably.
Fantastic
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.
Great Tool
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.
