In this day and age, that doesn’t sound too techie, but if you want to bring that same technology to your Mac computer, you can with iClapper Pro. The app costs $2.99, but a free version will be released in a few weeks.

How It Works

Basically you set up iClapper by assigning an action that will be executed when you trigger it by clapping your hands. For example, a single clap can cause iTunes to play or pause.

A double-clap could be used to put your computer to sleep. You can even set up a 5-claps trigger to say quit an assigned application. iClapper might not work the first time you use it, but if you follow the instructions and set it up right, it should perform okay.

iClapper Setup

After you download the app from the App Store, a tutorial will pop up when you launch the application. However, the tutorial blocks users from accessing the Preferences window of the app. Not a problem, you can use the following instructions here.


To use the app, your Mac of course will need a sound input device, such as the internal microphone. After you launch the app, you can access it from the menu bar. Click on it and select Preferences in the drop-down menu. Be sure your input mic is selected in the Input Device section.

You’ll probably want to try out the app right away, so go ahead; but to get the best recognition results, you need to calibrate the app for your personal clapping sounds.

Click on the Calibration section and select the + button. Clap your hand once and wait for the app to recognize the sound. Do it a few more times for good measure.

Now head over to the Actions sections and see what actions iClipper can perform by default. Notice you can click on an Action and change it. For example, you might want to change the Single Clap trigger to execute the Start Screensaver action.

When you clap and try to trigger an action, wait a few seconds to see what happens. Don’t keep clapping. If you’re running Growl on your Mac, you might get a notification that iClapper has recognized your clap.

Adding Actions

iClapper only includes six default triggers. To add more, you will need to use AppleScript scripts. To add a script, click the + button in the Actions section. Select a Trigger for it. Under the Action column, select the default action and choose New Action from the drop-down menu. Then add the script.

For instance, if you want download a favorite website with a double-clap, add the code as it appears in the screenshot below. Replace the URL in the quotation marks with your URL. Run the script to make sure it works, and then save your action.

I haven’t run into any problems with iClipper so far, but I do recommend to the developer that he designs a better looking menu bar icon – something more subtle and Apple-like.
