Tested it against pure 440hz tone and more often than not it was fluctuating wildly. When it didn't fluctuate it was either at least 5hz sharp or didn't register anything at all. It will work if you only need to find the general ballpark and then tune by ear the rest of the way but if you're looking for any level of accuracy, you'd be better off elsewhere.

I like the dark theme and clean, simple design. But the real "art" of writing a tuner is making it easy to use by finding a good balance between micro-accuracy and readability. This one's better than most, but its gauge updates a bit too frequently, making it somewhat "skittish" and making tuning take longer. I suggest comparing it with something like Stonekick's Pitched Tuner (also free), which really hits the "sweet spot" of usability IMHO.

Dont understand the negative reviews. It starts fast, shows a needle around the closest note. What more do you want? Of course the needle dances and jumps to other notes. Dedicated tuning devices do this too. The real world is full of harmonics and noise...
