This is the best one I’ve found – The Metronome by Soundbrenner Review

As a musician, there’s hundreds of options when looking for a metronome app. I’ve heard of this company but thought you could only use the app if you had the wearable metronome,but when I first installed the app and it gave me the option to just use it as a metronome, I was blown away! I just recently set up my account, which wasn’t an option with the other apps out there. the way you can change the time signatures and everything is truly remarkable! I am giving it a five star rating because that is what it deserves!
