Get a free app and tune from the iPhone.

Changing programs (the instruments) is easy and the tuning seems very accurate .Update; Have had it for a couple of months and it has held up better than expected

if you play a 12 buy one if you play 6s, suck it up and tune.

It does tune pretty well.

The tuning is accurate as far as I can tell

Now it won,t work even with new batteries
