ClockMaster - Time Regulator

The app isn't bad, however I get some important complaints which might have been a deal breaker for me. 1: when you high dollar for this app you only get the light version. You can't regulate clocks for precision. If you wish to do so you must buy the pro version. 2: the auto function to predict bph, according to this app my clock is 3min wrong a day. In reality it is 3 min wrong in 2 weeks. This means you have to do a wheel/pinion count when the clock is disassembled. 3: it might be hard to get the app to register all beats, and therefore be unprecise. It's not suitable for all clocks. After all these honest cons I think this app is useful for most clocks. But please fix the paid preview, that's just dumb! .

Nice app! Simple, yet effective. Helped me with my old wall clock.

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.

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.

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.

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!!!

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!

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.

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.

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).
