## Description

Reviews:
- Just great! I was thrilled to find this app. Does the job perfectly
- This app is fantastic. Honestly, it's priced too low
- Relevant for any pendulum clock

The best and most accurate app for Cuckoo and Pendulum clocks calibration.
Easily measure your Clock beats period and adjust it to a known correct value.
Turn your iPhone into a precise train count sensor with an unbelievable 0.001 milliseconds (1μs) accuracy!!
Get a quick and precise drift reading of how many seconds/minutes your clock is going to gain or loose per day.

Every Cuckoo Clock owner knows that a mechanical clocks are not as accurate as modern day quartz clocks. This is because the clock mechanism is influenced by temperature, humidity, barometric pressure, breeze and others environmental conditions and therefore requires frequent adjustment.

When you are regulating the pendulum of your Cuckoo Clock today, you are attempting to achieve the best timekeeping possible by a trail and error method by lifting the pendulum bob up or down and hope for a better accuracy.
Using this app you can finally get a reading of your Clock ticks timing and precisely calibrate it to a known value.

How to calibrate your Clock using this app:
1.	Run this App and measure your Clock timings using the iPhone microphone
2.	Use the Signal Gain and the Detection Threshold sliders to adjust the measured signal
3.	Select a reference timing for calibration from the clock reference table or set your own reference timing
4.	Read the accuracy level of your clock vs. the reference timing
5.	Adjust your Clock pendulum bob to get the best accuracy!
6.     Review how many seconds/minutes your Clock will gain or lose per day based on your current calibration

The app will presents your Clock beats period reading as well as BPH (beats per hour) and BPM (beats per minutes) values.
An accurate waveform display of the microphone signal will help you to adjust the tick readings for the best measurement.
Animated Indicators will guide you through the calibration process.

Manage the app Reference Timings table and add user defined clocks in addition to the predefined ones to support all your clocks.

This app will turn your iPhone into a powerful measurement tool which normally costs hundreds of dollars.

## Review summary

The app is praised for being easy to use, accurate, and versatile across clock types, and for offering good value. Common drawbacks include sensitivity to ambient noise requiring a quiet setting, a perceived cuckoo-clock focus with demand for broader clock support, and a desire for more clock references and easier sharing of data.

### Pros

- Easy to use and intuitive
- Highly accurate and sensitive for measuring beat/period
- Supports multiple clock profiles and works with many clocks, not just cuckoo clocks
- Affordable and great value for money
- Effectively tunes clocks and reduces trial-and-error time

### Cons

- Requires a quiet environment due to background noise sensitivity
- Cuckoo-clock branding; users want a universal, clock-agnostic name and scope
- Limited clock references/catalogs; desire to add/share more references and models
