Ratings and reviews

I might give it more stars, but I already paid for the previous version, which disappeared from my phone. Very disappointing.

Did I miss something? Peterson, the go-to strobe tuner for pedal steel guitar players has released an app that doesn't feature sweetened/tempered tuning for pedal steel? What gives? Everything else appears to function nicely and accurately and in a user-friendly way, but seriously, WOT NO PSG?!? 😮 PS If I did miss something and you can show me where to find a PSG setting I'll be happy to update this review... :)

Finally, the app I've been waiting for. I'm an avid follower of Peterson Strobe Tuners. I've acquired 6 tuners over the years and this one is as good as the rest. Super simple to use. Start the app then lay the your phone near the instrument amp speaker and tune away. This is just as accurate as the other Peterson Tuners that I have. The price for the app is very cheap. Bottom, line if you go to a gig and forget your tuner this one will save the day. I highly recommend this Peterson app.
