1. 3/5Doesn’t work

   I was told this was the best guitar tuner on the App Store, and it is... when it works. About 90% of the time, it can’t detect that I’m even playing a note despite the lack of background noise even when I’m right up close to the mic. When it works, it is very accurate and I’m impressed with the polyphonic tuning, but I’ve downloaded another app that, although may not be as ‘super high quality’, works reliably. And the problem isn’t my phone. I’ve used the app on a few phones before I rated it just to be sure, and it’s just not reliable for me. Maybe it’s just buggy, maybe it’s a user error or whatever, but that’s my experience. I’ve stopped using it, and I wouldn’t recommend it to anyone unless their willing to risk a few bucks. Again, though, it’s incredible when it works, hence the generous three stars.

2. 5/5Just like my pedal!

   I love my PolyTune app! It’s like my PolyTune Noir but I can use it with my acoustic when I don’t have the pedalboard with me. I have it set to strobe for super accurate tuning and it doesn’t disappoint. I have no idea how people are getting negative reviews going. When I tune, I set it on top of the acoustic so it’ll pick it up better. Try that out if it’s having trouble hearing you. Mine also sees individual notes I’m tuning if I tune with a capo. I can’t do the all 6 at the sane time thing that way, but that’s only used as a spot-check after I’ve tuned. That means it’s basically still a regular tuner when you use alternate tunings. Not a big deal. If it still gives grief with capos or alternate tunings, maybe try setting it to the chromatic tuner setting? I’ve never had issues, but they built that into the settings for some reason or another.

3. 3/5No capo functions

   I'd like to give this five stars, but I capo a lot of times… If it's so easy to add "de-tuned" guitar tuning options, why can't they go UP the neck from the regular E tuning, and do the F, F#, G, G#, A... etc. Seems pretty easy to add these features… Look, I know how to tune open and then capo after that, but a lot of times a capo messes with the tuning, usually makes One or two strings go sharp, so I like to tune right through the capo. Any flamenco guitarist would appreciate a capo function...

4. 5/5Beautifully done

   I was really disappointed when my trusty old Fastune HT6 became obsolete due to iOS 11 requiring only 64-bit apps, especially because the last time I looked for a more modern polychromatic tuner to replace it, I couldn't find one. I was relieved to discover the existence of PolyTune, which seems to work really well, and I love the simple, elegant interface.

5. 1/5New PolyTune update screws up tuner accuracy

   I've owned this App for years and its worked better than any other tuner on the App store, until it recently auto Updated itself to a new version with new look and function... The new version, is really quite insensitive and non responsive in general and specifically to the lower A and E strings of any acoustic guitar on all my iPhones and iPads including iPhone 7. Do not buy it - Since the company released their new hardware PolyTune clip product, it seems they deliberately dumbed down the App, to encourage the hardware purchase over the App.
