Funktioniert sehr gut
Man muss sich etwas Zeit nehmen, aber sie funktioniert wunderbar und macht genau was sie soll. Ich würde mir nur wünschen, dass man das Protokoll wie bei einer richtigen Zeitwaage auch ausdrucken könnte.

Good but very frustrating
At the top of my list of frustrations is the way data is handled. It appears to be streamed to memory rather than saved directly to a file. As a result, if the app stops unexpectedly, all recorded data from the current session is lost. This is utterly infuriating after one or two weeks of measurement, and it could be easily avoided by streaming data to a file rather than relying on a memory dump at the end. I cannot emphasise enough how frustrating this is. A far better approach would be to open a new file for each measurement and continuously write to it, with the option to append to the most recent file when starting a new session.
The spreadsheet exported has its own minor issues., the units are undocumented leaving you to guess (at least, I couldn't find them), and the export would be significantly more useful if each measurement row included the actual time.
A major issue is that any iPhone notification immediately stops measurements. Putting the phone into airplane mode helps, but it’s nearly impossible to prevent an iPhone from displaying a notification at some point. Ideally, the app should be able to continue running in the background, but I suspect that may not be possible on iOS. A workaround would be an option to manually restart a measurement and append it to an existing dataset.
In conclusion, the base price of the app is well worth it, but the additional spreadsheet export and long-term measurement functionality come with significant frustrations. These could easily be resolved by continuously streaming data to a file rather than relying on volatile memory storage (assuming that’s how it’s done).
Very good
Waste of Money
Clockmaster regulator analyzer
Don Brown/ frustrated customer
Great app for the Clock aficionado…
Will not work for 400-day clocks
Great app, used it for years.
Unbelievably helpful
Juts works well easily and simply
I have managed to set it to an accuracy of +0.2 seconds per day
That would have been impossible without this app.
So easy to use as well.
ClockMaster
Piezoelectric pickup
There is an adapter available on Amazon that allows you to plug in your Lightning charger and your Lightning dongle provided with your iPhone that you then plug the Pitch-grabber into. This is the only adapter that will allow you to run ClockMaster and charge at the same time. Using my iPad Mini 4 with full brightness and full screen it actually will also recharge it at the same time!
Great app!!!
Wonderful!
ClockMaster
Excellent app
Since I have got the app (one year ago), I found the app indeed very helpful for me to make pendulum clocks beat and work accurately.
It will take short time to adjust accuracy of clock if you know BM/BH of it otherwise you note current BM/BH then wait for the clock working for 24 hs and base on accuracy of clock you calculate actual BM/BH then adjust clock work with the new BM/BH.
Before when I didn’t have the app, it took me almost one week to make clocks work perfectly.
Please share me if any other app is better this app.
Very useful app
Excellent utility for antique clock accuracy
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!
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
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).
