Does the job – iSruthi-Tampura Sruthi box Review

My vocal teacher suggested this app for singing scales and warming up. I've never used a sruthi box for anything before, and I like this tool. It's fun to sing seconds and fourths and sevenths over this. I enjoy it for my vocal warmups. Works just fine.
