Just strum your guitar, and see the pitch of all strings instantly. - Guitar/bass mode - Drop-tunings - 1:1 port of the award-winning PolyTune pedal (Guitar Player, Guitar World, Premier Guitar, MIPA, NAMM Best in Show 2010, etc.) - Based one the world’s best selling pedal tuner used by countless pros such as Steve Vai, John Petrucci, Steve Morse, Orianthi and many more!

Verdict
The clearest difference is rating: Guitar Pro at 3.6 against PolyTune's 2.8. Guitar Pro also leads on update cadence (every 2 months vs every 40 months) and ratings volume (906 vs 80). PolyTune's advantage is ads (none vs shown) and review sentiment (66% vs 47%). On in-app purchases and device support there is nothing between them.
Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS
PolyTune costs $4.99 and Guitar Pro $6.99 up front. Neither carries in-app purchases, so what you see is what you pay.
Guitar Pro holds the better App Store score, 3.6 against 2.8. That said, the two scores are not equally well evidenced: Guitar Pro has 906 ratings behind it against 80, so its average is the more settled of the two. Written reviews complicate that: 66% of PolyTune's written reviews are positive against 47% of Guitar Pro's, so the app with the better star average is not the one people write more warmly about.
PolyTune ships an update every 40 months, Guitar Pro every 2 months. Both last shipped on November 6, 2026.
