ClockMaster - Time Regulator

We bought a used Howard Miller grandfather clock that had not been running for a long time. I cleaned it up and used this app to get it in proper beat and regulation. Awesome app! So much easier and accurate then using a stopwatch or counting the beats to set the clock.

Use it several times a week. Has been really useful. Would not want to be without it.

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 y

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 ap

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!
