We use the Vernier Go Direct pH sensors with the Graphical Analysis app on iPhone and it works really well.
Cheers

We recently bought Pasco pH meters from Cidertech House, but have to say that we're not that happy with them. When you put the caps back onto the sensors, it seems to bubble air into the body of the probe, half of them are nearly empty now. And one of them seems to be beyond repair - we tried calibrating it and it gave crazy results!
