Download of Idle Interval 1.1 for Mac was on the developer's website when we last checked. We cannot confirm if there is a free download of this app available. We recommend checking the downloaded files with any free antivirus. The program lies within Developer Tools, more precisely IDE. This free software for Mac OS X is a product of Tryblock.
From the developer:
The Idle Interval scripting addition enables you to develop more responsive AppleScript Studio applications. It gives you precise control of the idle interval, the time interval between invocations of your idle handler. Get and set the timing options any time, from any handler in your script, and even from scripts outside your application.
You may want to check out more Mac applications, such as RuneScape Idle Adventures, Shonen Idle Z or Music Intervals, which might be similar to Idle Interval.
