Best out of the 6 or 7 I've tried for acoustic, including Big F and GT. Other apps bounce around too much with acoustic guitar harmonics, this one is steady while still being sensitive enough to dial in the sound. Other apps always leave me with a flat high E and all strings a little off relative to each other, but this one looks and acts like a good analog tuner pedal. Highly recommended for acoustic. Better yet, it loads instantly and doesn't nag me to subscribe or try to teach me a song.

Only tuning app I use, one of the first installs on every new phone. Straightforward functioning chromatic tuner, completely free. I most enjoy the fact that you can tune to whatever key you want without forking up extra money, doesn't have to be standard or one of the preset tunings. Besides that, it's pretty accurate as far as I can tell, I've never noticed any tuning problems that I could attribute to the app (ie dead strings, intonation etc).

Overall, definitely one of the better tuning apps. I use this app for turning my guitar. personally my favorite, but I have notice a couple issues. Sometimes transitioning notes can take an annoying amount of time to process the change. Also lower frequencies, like the low E string has been difficult for the app to identify. Issues seem to slightly improve with higher volume.
