Perfect for flute and bansuri learners

This is an amazing app if you are learning Indian bansuri or western flute or violin. This app is perfect since it reads notes in Hindustani Classical notations. I don’t use this app for tuning but to make sure my bansuri notes are correct. Creator of this app should consider allowing export (email or notes) of notes played which will allow to check incorrectly played notes.

This is the perfect tuning app. If you have had lots of music in your past, if you have had music theory or if you just want you instrument to be in tune- perfectly, btw- then this is the app you need.
I have one other that works similarly and is specific for a guitar (it shows a green light when it is within a certain range of pitch) but this one is perfect for my ukulele.
