Pendulum Clock Time Regulation

>>> Check out the demo videos at ClockMasterApp.com ClockMaster is a clock timing software, in many ways similar to watch timegraphers, but specifically designed to work with mechanical pendulum clocks. The app analyzes the ticking sound of the escapement to determine the clock's running rate measured in Beats Per Hour (B/H). This rate is then compared to a specified Target Rate, and the Error is reported as Seconds Per Day fast or slow (±S/D). The speed of a mechanical pendulum clock is not constant, fluctuating with age and wear, spring tension and even temperature. The ClockMaster app was created with a focus on accurate long-term measurements where traditional timers often do not function very well. For the professional horologist or interested amateur, you can now test in the field — put the clock in exact beat and regulate the clock with just a few hours of testing. For increased rate accuracy and in depth investigation of clock movement's behavior, you can conduct long-term measurements for up to two weeks (ClockMaster Pro). Branded, printable PDF reports can be generated for each measurement, and the raw data exported as .csv file for graphing in a spreadsheet (ClockMaster Pro). ClockMaster Pro (in-app upgrade) provides these additional features: • Save and share branded, printable PDF reports for each measurement • Export raw measurement data as a .csv file for spreadsheet analysis • Conduct long-term measurements of up to two weeks }

I have a very old Seth Thomas 30 day gallery clock and I was able to easily set the beat and calibrate the time. Thanks for the great app.

The app performs beat measurement very well. That said, the app does have some very frustrating aspects, which, in my opinion, call into question the value of paying extra for the spreadsheet export. 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. Assuming you don’t lose your data, the spreadsheet export has its own issues. In my case, the recorded duration is incorrect, 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 a timestamp. Another major issue is that any 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 reasonable 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).

I came upon this app after years of using a free, but very limited beat tracker. This app is exactly what I wanted, nicely designed, good resources, seems to work very well. Even using the built-in mic on an iPhone, or the microphone on Apple EarPods, it can track a movement very well, even with other distracting noises as there is a selectable filter. Yes it has a cost but I believe it is fair, at least so far and sometimes you have to pay for the best there is. It is certainly a good alternative to buying a much more expensive dedicated instrument.

Simply doesn’t work. The free app for cuckoo clocks works better!!!!

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. Don Brown/ frustrated customer

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