"title": "Unreasonable ads…",
"body": "I want to preface by saying: I understand a free app might have some ads, but this is excessive. I downloaded this with the hope of using it as a chromatic tuner, since my clip on tuner doesn’t have that option. In the free version, during 1 tuning session, I had to watch through 2 ads (one when I opened the app, and another after I tuned maybe 2 strings). Then there’s the flashing ads right in the middle of the screen that are conveniently located right where you might accidentally tap them. My tune never sounded quite perfect, so I clipped on my regular tuner and realized that E was almost a half step flat, and D was sharp. So not only is it frustrating to use, but it can’t even be accurate?? I’m not sure how this app ended up with such great reviews, maybe the older versions were better. But the 2026 version is horrific, and I used it 1 time before deleting.",

"body": "I used this product for a day or two, then paid $5.99 to upgrade so I could do more with it including turning ON my iPad microphone which works just fine. It isn't listed as wanting access to the mic. ALSO I wanted to turn the display so I could see the tuner in lanscape mode (easier to see for me) can't do that either. I see NO difference between downloading the Free version vs the Premium. I can ONLY use the tuner in portrait mode and only for guitar. Something is seriously wrong with the overall programming. My iPad works just fine.",

"body": "I have been using a different app and it did not tell me if I needed to tune tighter or you know. I am kind of new to guitar and I broke the low e string string and had to restring. I was terrified that one of the strings was going to hit one of my eyes or my face so I was just putting off tuning. I found this app but I have one suggestion. You should add a way to like tap the string your tunning so it doesn’t think you are doing a different string than what you are. THANK YOU SO MUCH",
