I got this tuner when I bought my Uke. It has three options for tuning but I use the Chromatic setting for my Uke and Guitar. The clip expands for a thicker head like on the guitar and holds solidly to both instruments. The only negative thing I have about it is, it tends to delay sometimes up to 8 plucks before it registers and is usually the wrong note. Keep plucking, it will eventually notice the string note and give it's +/- for the right tuning. I've plucked a D string for up to 15 times and it doesn't register then when it does, Reads G for a bit then comes down to D. Oh well, since I know this, I don't get frustrated. Nice little tuner.
