Tolle App für Pendulen und …

andere Pendeluhren.. Das Einzige, was mir fehlt ist eine akkurate Anzeige der Beat-Frequenz - gemeint ist: wenn das Pendel nicht gleichmäßig läuft, sieht man das zwar im durchlaufenden Display, aber man hat keine Regulierungsmöglichkeit dafür. und ein gleichmäßiger Pendelschlag ist eine Grundvoraussetzung für eine genau gehende Uhr.. Vielleicht lässt sich das noch implenentieren?!? Trotzdem gibt es volle 5 Sterne dafür.

Missing?

My app would be more helpful if it showed the level indicator. How can I install this please?

Great timepiece audio analyser

Got this to calibrate a few old stopwatches and clocks. It works super well. Gives instant readings of accuracy instead of just long winded trial and error. It’s important to get the gain and threshold set right plus phone positioning relative to timepieces. Quiet environment helps also. It simply listens to the tick tock then gives you the data you need. Fantastic app. Thanks.

Grandfather Clock

Once I realised how to set up a 2 second pendulum, very helpful app indeed to calibrate our 160 year old long case clock!

Delightfully simple!

The app allowed me to get my Garrard back in beat in a few minutes. Well worth the tiny price of the App.

FAQ

What does the Cuckoo Clock Calibration app do?

This app turns your iPhone into a precise sensor to measure the beat period of cuckoo and pendulum clocks. It helps you calculate how much time your clock gains or loses per day and guides you through adjusting the pendulum for optimal accuracy.

How accurate is the app for measuring clock beats?

The app boasts an impressive accuracy of 0.001 milliseconds (1μs), allowing for highly precise measurements of your clock's ticks. This level of accuracy is crucial for fine-tuning mechanical clocks.

Is this app free to use?

Yes, the application is available for free. There are no in-app purchases or advertisements mentioned, making it a completely free utility for clock calibration.

What kind of clocks can I calibrate with this app?

The app is specifically designed for the calibration of cuckoo clocks and pendulum clocks. It provides a reference timing table that includes predefined clocks and allows you to add your own custom clock definitions.

How do I use the app to calibrate my clock?

You'll use your iPhone's microphone to measure your clock's timings. The app provides sliders to adjust signal gain and detection threshold, a reference timing table, and displays your clock's accuracy. You then manually adjust your clock's pendulum based on the app's guidance.
