As long as you have a way to feed the signal into the unit, yes. There’s no microphone on it to pick up the sound.

Hell, you don't even need a paid app. I use the free Fender tuner app. There are TONS of free tuner apps.
Well, what are you using it for? If it's for a mobile device, just go into the app store and search for guitar tuner. Any one that just says "get" will be free (no risk of viruses if you use iOS).
No, sorry; I keep forgettingGarageBand has a tuner but does it work for acoustics with no pickup or microphone?

I keep a cheap (like $7 on Amazon) acoustic pickup I use for my ukulele, mandolin & such handy. Its the stick-on kind but instead of the double-stick tape, I use PartyTack which won't harm finishes and transfers between instruments quickly & easily.
Then I can use the Axe FX tuner as well as amps/effects. Am sure I'm not the first to create presets for mandolin, banjo & others. For actual recording I use a condenser mic or a Barcus Berry pickup.
How does the acoustic pickup sound? "PartyTack" you say eh? So one could put pictures (printed pictures) on one's guitar? I'll have to remember that .
I know someone that uses partytack to put the set list on the back of their guitar.
