- 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.

Ratings and Reviews
Feature Request
This app is wonderful! I just upgraded my Grandfather Clock with a new Hermle movement and was not looking forward to spending a week or more calibrating the pendulum. Within a few hours I got this baby down to gain or lose just seconds per day. This tool will be a tremendous time saver to keep my clock running at it’s finest.
The biggest problem was getting a good run - the iPhone microphone picks up so much background noise that it is difficult to complete a calibration pass. I had to wait until everyone was in bed before I could get good, reliable readings. Just the dog’s nails clicking on the hardwood floor was enough to trigger an upset.
My suggestion (Feature Request) is, once you’ve reached a high level of confidence in the beats measurement, put guard bands around the measured beats. That way, any noise outside the guard bands would be rejected.
Not only cuckoo clocks!
I used this app to successfully measure the rate of a 1944 Hamilton Model 21 marine chronometer. These timepieces were used for navigation of large ships of the US Navy during WWII and they are arguably the most accurate portable mechanical timepieces ever made. The app works well to measure the period of the clock. In fact, it works much better than my other software that is better suited to wristwatches. I suspect this is because the wristwatch timing software looks for an acoustic profile of a wristwatch lever escapement, and gets confused with the detent escapement of the Model 21. The app recently improved its resolution to 1 us, which makes it ideal to measure the Hamilton. The period of the Hamilton is 500 ms, so the improved resolution permits an adjustment of rate to within 0.17 s/day.
Thanks Nir.
Works well. Could use features.
This works well for what it is. Its accurate and informative making clock tuning much easier. It would be great to have broader clock options. I used this for a one to one grandfather clock, which it’s pretty easy to see it going at 60bpm but the app won’t let you use this as a reference. I also have a mini clock that ticks rather quickly, so there’s no reference for this. It would be awesome for the community on the app to be able to share references with everyone when they get certain clock types tuned just right. Maybe showing the brand if known, the size, and maybe even an image of the clock.
Developer Response ,
Hi,
I was very happy to hear that my app was helpful for you.
Thank you for the review.
Regarding your comment, you have the ability today to edit the current reference timing manually and add a movement timing that you set for yourself as a reference. In addition, I’m working these days on having the option to add more than one user timing to table so you’ll be able to have as many reference timings with clock names as you want.
I’ll appreciate if you could refer other relevant users to this app.
Thanks,
Nir
