Great to match pitch – Tuner Lite by Piascore Review

Keep in mind that this is strictly a tuner, and not a pitch pipe. If you want, say a G, you will need to download a pitch pipe. Note: Because it works with the internal mic on your phone, any Bluetooth device (in my case, hearing aids) will interfere with the tuner app.
