Web apps are common place, but web apps that do not require internet access are not. In this project we show you how we made a BPM Counter in a simple HTML page coupled with vanilla javascript (see here). If downloaded, this widget can be used offline - ideal for musicians who want to create but do not always have internet access. Even better, by using the OSX dashboard app (which never seemed that useful before), we can make this BPM Counter extra quick to use.
