Watch Tuner Timegrapher

Saved me over $100 on a timegrapher. Bought a $10 lapel microphone off Amazon, app takes a little playing around with on settings but once you find the sweet spot it works like a charm. Would love to be able to add more info about the test pieces and a picture. I’d purchase this app again.

Genuinely shocked at how well the app works, off the bat with the original settings it worked great, just use the apple ear buds with the microphone and set on top of the movement and it works a charm

works well on my loud ticking Waltham pocket watch. Data collection worked fine, amplitude, lift angle, and beat accuracy all great. BUT, program says watch is losing 10sec / day when the watch is demonstrably and consistently gaining about that much per day. So how useful for regulating a watch? Developer says I should regulate my iPhone. No mention in HELP or directions as to how or why. If app runs on a phone it has access to internet time, what’s to calibrate?

It works great under a particular setting. You will need to figure out it with your hardware. Try different settings and try lowering the sensitivity. Then it will work properly even in the normal room condition.
