Great app! Accurate and easy to use. Nice one for multi instrumentalists! Highly recommended. A+++

Great Tuner…! Very accurate and easy to use. Nice layout and UI! Use it every day!

The chromatic scale is definitely very helpful. For singers, it is helpful as when I sing a note, the tuner picks up exactly what note I sang. This is very helpful, especially for acapella singing groups. Very helpful tool! Highly recommend.
