Introduction

Clock Tuner App is a powerful tool designed for measuring the BPH (Beats per Hour) of mechanical watches. It utilizes a microphone to accurately measure the BPH and displays the time error per day. With the basic version, users can view a wave graph and pulse interval histogram, while the frequency display feature is available with a premium upgrade. Before purchasing the upgrade, it's recommended to test the app with your watch as it will function as a premium version for 30 minutes. Not compatible with digital clocks and noisy environments. Ensure the microphone is directed towards the watch. Click here to download Clock Tuner App and start optimizing the performance of your mechanical watch.

Clock Tuner is a timegrapher app designed to measure the Beats Per Hour (BPH) of mechanical watches. It also displays the time error per day. The app utilizes a microphone to measure BPH. To achieve accurate results, it is recommended to plug in a microphone into the phone and attach it to the back of the watch.

The app has several features, including a basic version that displays a wave graph and a pulse interval histogram. However, to access the frequency display, users need to upgrade to the Premium version. It is advised to test the app with your watch before purchasing the Premium upgrade, as it will be available for 30 minutes. The app is not suitable for digital clocks and does not work well in noisy environments. The microphone direction should be directed towards the clock for optimal performance.

In terms of user reviews, Mr. Kojima recommends the app and provides positive feedback in a review posted on a watch forum.

The app offers a sensitivity setting with options for high, medium, low, and three manual settings. This setting determines the sound amplitude threshold for detecting clock sounds. Adjusting the sensitivity can allow for more environmental noises or better measurement accuracy for hand watches.

The detected frequency is displayed in different colors, with red indicating smaller drift during measurement intervals, while grey suggests possible measurement errors. The average frequency may not calculate at times, instead displaying NaN. It is important to note that the detected frequency should be continuously shown in red.

The pulse drift percentage is calculated as the absolute value of the difference between the maximum and minimum detected frequencies, divided by the detected frequency during one detection cycle (abs(max detected frequency - min detected frequency) / detected frequency).

There are two graphs shown in the app, the upper graph displaying bars of almost the same size, while the bottom graph shows the amplitude of the sound wave recorded from the microphone.

As for future development, it is not explicitly mentioned whether newer versions of the app are being developed. Users have the option to provide sound samples by sending a waveform or mp3 file to admin@athumbcut.com.

In conclusion, Clock Tuner is a useful app for measuring the BPH and time error of mechanical watches. It provides various features and settings to customize the measurements, with an option to upgrade to the Premium version for additional functionality. The user reviews and positive feedback from Mr. Kojima on a watch forum add credibility to the app.
