Not sure if this is the right place to put this... My band is thinking of using the app "Bluetooth metronome" to practice with. Anyone use it before? The App Store has no reviews. We all have iPhones or iPod touch. One person buys the app for 1$, the rest of us get the free Bluetooth metronome receiver app for free. No more need to run the click track through the PA. I think it could work! We just need some earbud headphones and our phone/iPod. What do other people use for click track during band practice? We found running it through the PA was not ideal.
