This is a great tool to practice with, the only drawback is if you need BPM that is not in the list then it will not help you. But it can save you $80 for a real metronome, and that $80 could be used for a nice headphone set.
I find the best way to use it is to download the zip file of it and open it, create a play list named metronome or what ever. Then when you want to practice go to that play list and click on the BPM you wish to practice. Click on the repeat button on your player. I use it with Windows media player it it does not do the 15 second rest like it does online, it just keeps looping. Thanks for this app. Bob.
