Very useful app

Update: the latest rewrite has made this app useless. If I could, I would restore the old version. It used to work quit well. Now useless.

Excellent utility for antique clock accuracy

Thanks for programming this handy ClockMaster utility that's perfect for home users like me. It can assist in calibration of clocks post-service in good working order.
As for wrist watches, I've found I can use it or 'experiment' with my 1956 vintage Omega Seamaster Calendar, and others, but first I record the watch beat in extreme HD quality using an 'expensive' voice recorder (mine is an Olympus DM-670. I can then play back the hi-fidelity recording (amplifying if necessary) via good speakers, directly into ClockMaster...
Thanks for a fun & useful horological utility!

Absolute con!

I even bought the expensive sensor!?? I fell for this hook, line and sinker!
It has no idea what constitutes a clock! Simple small ones, it can’t manage because there’s nowhere to clip the transducer! The microphone on the phone does bugger all other than compound the issue.
It can’t do larger ones unless you get them out of the case to get the mike on!!! Even then, it is confused by clicks from the movement.
It can’t distinguish tic toc from the cat with asthma four doors away.
It is completely useless with any kind of master clock because it cannot distinguish a click from a clonk!
I have been optimistic and regulated a few clocks with it! Absolute disaster! I can do vastly better by intuition over a couple of days! Its results are generally worse than educated guess work!
DO NOT PURCHASE!!!!!

ClockMaster did the job

I inherited a 114 year old Ithaca grandfather clock with a Griffith movement and used this program to tune the movement. After getting into the clock, I found that it was not set up correctly and didn’t work at all. After figuring out how it was supposed to be set up, I used the program to set the beat and regulation. I started out with zero knowledge on how a clock works and muddled through the process with the end result being a clock that keeps time. Hurray.
The only issue I had was that the auto function for estimating the target rate (for BPH) did not work on this clock at all. I did calculate the actual BPH from counting the number of gears and pivots in the gear train and with the correct BPH imputed, the app worked perfectly. I did splurge on the external Peterson pitch grabber which was money well spent($15 at Amazon).

Does work.

I use this app with a peterson tuner and by placing the clamp on the winding key find that it works very well without interruption from outside noises. As I have several clocks close by this was a problem with external mic. Would I recommend this yes in a clock beat I would, sorry! If you have trouble look at the tips within the App.

Simple but does the job

I used this to calibrate my cuckoo clock. It picked up the pendulum clicks just fine using the internal mic, with no need for an external mic or sensor. I'm definitely no horologist, but this seemed to do the job. When I had a problem due to an iOS version issue, the developer responded within a few minutes and had a fix quickly.

It would be nice to have plots to look at drift rate and periodic error. These are available in the Pro version, but even in that it will not make plots - just allow you to export the data to a file to be viewed elsewhere. Would be better to have the plots right in the app.

Don’t waste your money

The app would be fine except the fact that they say to use iPhone headphones with a mic to get better accuracy and yet the results are worse with an apple headset mic. Without the headset and having the phone literally sitting on the clockwork and I had to have it set at 8.7 out of 10 for sensitivity and it still wasn’t quite right. Any higher and it had false positives and at this setting it still missed some of the ticks.

Great little app

Easy to use and graph outputs makes diagnostic much easier

Mixed feelings

I question how useful this app really is. It’s fine for getting a clock on beat but only by taping the Apple earbuds so the microphone is taped to the metal of the movement.

I purchased the mic they recommend and it’s huge and the sensor doesn’t touch the movement due to it’s odd shape so it picked up NOTHING.

I purchased the pro version and it really didn’t make much difference.

If you just want a way to set it on beat while in your shop it’s fine but it doesn’t exactly look professional to be taping your earbuds to someone’s grandfather clock while your in there home.

There has to be a better way.

I didn’t have good results timing a clock but that may be me.

It has soooo much potential but it needs a mic that works with it.

Church Clock Regulation

Currently using to time a turret clock in local Church. 1.25 second beating pendulum. Crude adjustment via rating nut then this app clearly shows the effect of timing washers on the pendulum (old pennies used on the great clock at Westminster). Yet to try on smaller timepieces. May consider upgrading if further trials OK.
