Clockmaster regulator analyzer

The manual clearly shows a setting for external mic operation yet my version only gives me the option of internal iPhone mics. Have sent 3 messages to support for help, and they ignore me. Can only assume the app is flawed.

Response from developer

Hello, we haven't received any messages from you, please contact us at apps@onyx3.com The app works with external microphones and sensors, it requires an adapter as described in the documentation. This is explained in the documentation and clearly shown in the videos here: https://clockmasterapp.com/

Great app for the Clock aficionado…

One of my hobbies is to clean and repair old grandfather clocks. This app helps in a very simple but elegant display to set the bit, the pendulum symmetry, and other more advanced features. I highly recommended it.

Will not work for 400-day clocks

I really don’t understand why they’ve set a bottom threshold on how many beats per hour you can measure. My clocks I work on operate at 8 beats per minute. I can get it to measure correctly due to this threshold. It would be useful if I could set the BPH to 480.

Response from developer

400-day clocks are not supported, only rates 2400 to 18000 B/H. Please contact us for a refund if the app is of no use to you.

Great app, used it for years.

I wouldn’t be without this app, it works really well. It can be a fiddle getting the sensor in the optimum place but once there it works. The app can’t position the sensor for you - you have to do that yourself. For those saying the bpm fluctuates so the app is no good, bpm can fluctuate. That might be a slight tight spot somewhere, or simply a pendulum taking a while to “settle” or any number of reasons. This app is simply showing you what the clock is doing - you do need to understand what the app is telling you and you need to understand horology. Like any tool, you need to understand how to use it.

Glad you like it! Completely agree.

Unbelievably helpful

I was getting my butt kicked by a wooden mechanical clock I made. I was using metronome apps, stopwatches, etc. to try and get the beat and regulation right. I'm talking weeks of time spent. Wasted. I finally found this app and it does everything it says, and does it very well. The only complaint I have, if you can call it that, is that I wish they had the beat delta info on the regulation screen. I was considering upgrading to the pro version but it's another $19.99 and it doesn't really tell you everything that is included with that upgrade.

Juts works well easily and simply

I downloaded the app and used it to help me set up a pendulum clock

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

This app is excellent. I work with clocks professionally and this app does the work of software costing 3 times as much. Great work.

I’ve found that the Peterson Pitch-grabber works very well with my iPad and iPhone.
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!

My ship’s bell clock had been running almost a minute-a-day off for years. With a few iterations of this app it’s now within a second a day!

Excellent app

I’m a clock’s collector so I always do servicing and repairing pendulum clocks.

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.
