United StatesThe 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.
Excellent but needs some slight changes
This is a great app for regulating a mechanical clock…not just cuckoo clocks, as the name would suggest! You do need to find out the proper beat frequency of the clock movement you’re trying to regulate (usually 60 BPM for grandfather clocks, but varies widely for other clocks). I have three requests that would make the app perfect for me: —please allow a frequency of 60.000 BPM! I don’t know why the app doesn’t allow this. I use 60.001 BPM for my grandfather clocks, which is close enough, but it’s kind of annoying to have to do so. —you should really repackage/rename this app to be for all mechanical clocks, not just cuckoo clocks. The cuckoo clock animation is cute, but I think more people would purchase the app if it were clear that this can be used for all mechanical clocks —it would be wonderful if the app would save the data once a measurement is completed. Making a slight noise to pick up the phone or to take a screenshot completely disrupts the completed measurement, and it disappears. Thanks for a great app!
United StatesCan’t beat it for $0.99
Dials in a clock incredibly accurately.
United StatesPretty accurate for setting your clock
I have a cuckoo clock that is not in the database, a Regula 35, a one day movement. Through trial and error I’ve got it pretty close to about 1min/day. I’m not about to try and count teeth on gears and pinions to calculate the pendulum rate but found I had to get a longer pendulum stick after cleaning and oiling. Don’t know why this was but after trial and error got it pretty close. Was hoping the developer might have a proper reference for that particular movement but here is the reference that I have developed for the Regula 35; BPH 6755.25. BPM 112.587. Period 532.919. I hope the developer will publish a corrected version but if not this is about as close of one that I can get. I hope this helps anyone with that particular movement. A great app and thanks.
United StatesDirections
I believe this app works but the directions are so confusing I can’t get it to work. A you tube tutorial is needed.
United StatesFeature 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.
United StatesPerfect app for anyone with a cuckoo clock!
I got a request from a friend of the family to try and fix their cuckoo clock. I knew nothing about them, but after some YouTube videos and this app the clock is running again and keeps perfect time! I was a rank beginner but this app is very intuitive, easy to use even for a new guy.
United StatesI got the beat, I got the beat!
Great app if you need to set the beat on a clock and then time it! Not just for Cuckoos! Tells you when you have a consistent beat and then whether you need to raise or lower the pendulum. You need a quiet place to use it. One of the best apps I’ve ever had!!
