Features & Capabilities

Clock Tuner is a specialized timegrapher app designed for mechanical watch enthusiasts and professionals. It measures the beats per hour (BPH) of mechanical watches and displays the time error per day, providing insights into watch accuracy. Utilizing your phone's microphone, it captures the watch's ticking sounds to perform detailed acoustic analysis.

The app features a wave graph and pulse interval histogram in its basic version, while the premium upgrade unlocks frequency display for deeper diagnostics. Clock Tuner recommends using an external microphone connected to your phone, positioned near the back of the watch for best results. It operates best in quiet environments and supports various watch types, including Rolex and pendulum clocks, with customizable sensitivity and sample duration settings.

With practical presets, an informative FAQ section, and ongoing development, Clock Tuner is an essential tool for anyone looking to monitor and tune mechanical watches accurately.

User Reviews

Clock Tuner is praised for its accurate tick detection and ability to finely adjust mechanical watches and clocks using a phone microphone. Users find it easy to use and consider it a cost-effective alternative to professional equipment. However, the trial period is brief, and some experience difficulties with purchasing the pro version or app stability. UI readability and lack of in-app documentation cause confusion, while occasional concerns about error accuracy and support were raised. Overall, it's valued for functionality and price despite some rough edges.

Pros

Accurate and reliable detection of watch and clock ticks/bpm with phone microphone.
Effective for fine-tuning mechanical watches and adjusting clocks with impressive precision.
Easy to set up and use, with quick results compared to other similar apps.
Affordable alternative to professional timegrapher machines, offering great value for money.
Supports custom beat rates and provides useful error and beat error metrics for adjustments.

Cons

30-minute free trial is very limited, requiring purchase to continue usage, and the upgrade process can be problematic.
UI issues such as tiny font size, lack of zoom or readability for graphs and error displays.
Limited documentation inside the app explaining terms like beat error, graph interpretations, and settings.
Occasional stability issues requiring app reinstall or clearing data to restore functionality.
Some reports of suspicious or fixed error rate increments, causing accuracy concerns and lack of developer support.

I rebuilt my wall clock, including the pendulum, and had no idea where to set the length. The Clock Tuner app was wonderfull to use. I could confidently adjust the nut rapidly to get in the "ballpark". Within an hour, I could set the nut to 5 digits BPH accuracy. One issue was the custom BPH of 6000 could not be selected with the Up/Down buttons, and therefore error rate would not calculate. However it could be selected by tapping on the BPH field and tapping the 6000 "radio" button.

Overall Excellent! There are a few quirks tho. Clip-on timegrapher microphones solve the lack of sensitivity, and running it through a beat indicator pick-up ($40-$50) on Timesavers Website. Three options are standard. Low, Medium and High sensitivity. It would be absolutely incredible if the microphone pickup could be adjusted with a level indicator and external sound through the phones speaker. I would definitely pay more for that app. But: this app is the best current one out there-
