I needed to tune my violin, and as I was unsure how to do this myself, I decided to download an app to help me. SimplyTuner seemed decent, it looked nice and had good reviews, so I took a chance on this one. It can’t be too hard to get tuning a violin right, can it? I opened SimplyTuner , and got to tuning. Tuning the a string went just fine, and I moved on to my e string. I got it pretty tight, but it still said my e string pitch was very low, and that I should keep tightening the string. As I’m no expert on tuning violins, I decided to trust SimplyTuner . I go to tighten a bit more, then snap! My string breaks. The strings were in good shape as I had just bought my violin new, so the string did not break because it was worn and was gonna break sometime soon. It broke because I was told to keep tightening it, when apparently it had already reached a good tension. Now I’m out a fair amount of money as I will have to buy a new string or strings. That’s why I’m giving SimplyTuner 1 star.
