PolyTune

When it works it does its job fine, but if you leave it running in the background it freezes and you have to hard restart the app every time.

I used to love this tuner app, the best around. Stopped working for iOS14 so pretty much useless now. Would love to see it working again.

I used the Polytune everday. Very accurate app. But with iOS14.2 it doesn't work anymore. Please update!

Still no update for the bigger iPhones.
Thats a shame, cause it works great.
Looks like they made it, and never intend to update it again. Last update is from 2010...
I woudnt recommend this app anymore... Unless you have an iPhone 4.

This app was made for iPhone 4, and needs to be upgraded for the iPhone 6. The resolution is too low and the aspect ratio is incorrect.

I really like this app, however please update the app to iOS 7 and update the display to fit iPhone 5/5s.

First tuner app dat works right of the bat without jittering.
Wors as the real pedal. Love it!

And not only for guitars. Used it once at a baroque concert when everyone was tuning their instruments. Fun to see.

Perfect tuner. Beautiful and clear interface, accurate tuning.
Don't like the new icon. Looks cheap.

It's an amazing app, your guitar sounds nice. You can also tune your voice, so that's also nice. I don't know about tuning your bass, but I think that it's also amazing. Just an awesome app! Might be the app of the year!
(^-^)

Display was perfect, nice sharp green and red dots. After the update it's gone blurry, what's wrong with my eyes! Very ugly now. A hazy look, liked the bright clear one much better, pity. Functional is superb, but looks are awful now.

Zowel alle snaren tegelijkertijd als de snaren afzonderlijk herkent deze app prima. Hierdoor kun je snel en nauwkeurig je gitaar stemmen.
Gebruik een clean geluid of leg je iPhone vlakbij het klankgat van je akoestische gitaar.
Zeer bruikbare app! Prijs vond ik eerst aan de hoge kant, maar dit is de €7,99 wel waard hoor.

De applicatie ziet er wel gelikt uit. Maar het stemapparaat is in de praktijk niet bruikbaar. Het herkent slechts met moeite de individuele toon, en alleen in deze modus heb je er wat aan. Het alle snaren tegelijk strummen en stemmen werkt gewoon niet. De leds gaan alle kanten op en de bijbehorende ledbar veranderd niet waneer de desbetreffede snaar stemt. Niet akoustisch en niet elektrisch. Het idee vind ik overigens super. Ik ga zeker in de winkel een keer de pedaalversie testen.

Dit is het beste stemapparaat dat ik ooit gebruikt heb. Sla alle zes de snaren in eens aan en check welke bijgesteld dienen te worden of stuk voor stuk en nauwkeurig bij te stellen. Mijn gitaar klonk nog nooit zo goed zo snel.
Volgens mij had ik hem wel voor minder dan 7 euro 99 maar ik zou hem hier voor kopen nu ik dit weet.

Thanks to this app my iPhone is used more as a tuner then my actual hardware tuner. It just looks good and works amazingly well.

The physical box is one of the great invention off the last year and bringing it to the iPhone... just rocks. I play acoustic guitar and makes me really in tune where ever I am. Thanx! Edwin
