We used the iPads to help us tune today. The FREE apps we used are called "Pano Tuner" and "Tuner Lite".
The musicians rated both apps and decided overall they liked both. "Pano Tuner" is easy to read and "Tuner Lite" was able to play all of the pitches they were tuning to. The third year string students have been encouraged to either use the online versions or download the apps to their devices at home so the can tune for themselves!
