ClockMaster is an app dedicated to the measurement and regulation of mechanical pendulum clocks. The app uses a microphone to capture the audible ticks of the clocks escapement and pendulum, and then determines the beats per minute and the rate of error in seconds per day fast or slow.
This app has been created specifically in mind for both the clock owner who just wants to know how fast or slow their clock is per day to adjust it, and also for the professional horologist for in depth testing of movements or field work.
For the clock owner it is a simple process of mic calibration, putting the clock in beat with apps help and then the measurement takes place. An error rate will be shown and you can adjust the clocks pendulum accordingly. (see website for more info)
For the professional horologist or interested amateur, you can now test and regulate in the field accurately - put the clock in exact beat, regulate the clock accurately with only a few minutes of testing. On the bench you can test for long periods for increased rate accuracy and stability. The rate is a running average so the longer the test, the more accurate the rate. Accuracy of BPM’s to the 4th decimal place and rates accurate down to +/- 1 second a week (in-app upgrade). You can add external sensors to also aid in accuracy (see website for more info). There is an added feature for saving the raw tick times in a data file that can be imported to your favourite spreadsheet for graphing and in depth study of escapements and wheels (in-app upgrade).
• Microphone sensitivity level adjustment for better, more accurate sound pickup
• Beat error - Compares the time difference, Δ, between ticks for adjusting the clock in beat
• BPM - Automatically figures the beats/tick per minute of the clock or allows a manual entry of BPH (beats per hour) if known
• Rate - Shows a continuous running average of the rate of the clock in +/- seconds per day
• Count - counts the total number of beats/ticks within the sampled time.
The app works on any pendulum clock - a longcase, mantel, wall, bracket, dial or carriage clock, et cetera. Also works with quartz clocks and watches or anything that produces an audible tick that you would want to measure or regulate.
There is an in-app upgrade that provides these additional features:
• Increased BPM measurement to the fourth decimal place - 1 sec per week rating accuracy
• Raw timing data export to file for use in spreadsheets to graph and analyze
• Support for external piezo acoustic sensors

Very useful! Works as advertised
This has become my go-to app when I'm fine tuning a clock, whether it be a perfect tick-tock or getting it timed to as little gain/loss per day. It has been frustrating in the past as the app didn't support my iPhone 5-5S, I had to resort to an old 4 for it to work. Just tried it on my 6S+ and had no problems!
I haven't upgraded to pro yet but I am interested as I have a piezo microphone with a 3.5" jack and instead of using my small amp next to my phone I'd love to be able to plug it into my phone and reduce the background noise. $20 is hard to swallow though. Now if it were say $5...
This app helped me resetting a grandfather clock I had to disassemble and clean & oil. The iPhone ear buds work far better than the internal Mic which is almost useless. A clip-on piezoelectric pickup would be much better still.
They only thing I don't like is that only an absolute delta is shown. It works be most helpful if there was some indication of which half of the cycle was longer/shorter when adjusting the balance. I ended up using a flashing metronome to tell me whether I had to tighten or loosen the pendulum leader offset. Lose one star for this deficiency.
I've tried a couple other apps but this is spot on. I would highly recommend.
After getting the cable and upgrading it works great with the pickup from my old broken timer. Very accurate and easy to use. The auto calculate function is a great feature. Recommend for any body looking for a nice timer. Price of app and a cable is around $40. A lot less then the cheapest time you can find. They start at $200 and go up.
