On their company site they list all the compensated tunings without clear mention when comparing that with the software tuners they and several other features aren’t included for the price as shown.

not the easiest app to find your way around. however, once you get it set up, with the sweetener you want to use, the actual tuning and tuning interface is amazing. if you didn’t already need an iphone, this app alone would justify having an iphone for a musician.

There are lots of tuner apps available, some better than others, but if you’re looking for a truly professional grade tuner app, this is the only way to go.

Goes hard in the paint like flocka flame.

App doesn’t work well, especially compared to the competition. Notes just don’t seem to track well, seems to be a sensitivity issue / calibration between mic input and the strobe UI. Love my strobostomp but this app isn’t worthy of the Peterson name.

Perfect for brass players. Picks up great and the trumpet sound doesn’t distort the app.

This has to be about the worst thing Peterson has designed- constantly flashes between notes when I’m trying to tune an acoustic guitar in a whisper quiet studio environment- i don’t know how it can’t distinguish between an E and A string. I ended up just going back to my old insTuner app that’s cheaper and works.

Very precise tuner, works very well
