I use this app almost any time I need to tune my bass and it sounds very good but sometimes the pitch on the app just changes still good though 👍
Sure, this app isn’t the prettiest and doesn’t have the best displays, but it is extremely accurate and helps tune my bass with ease. Thank you for this great app!
This is a great app to pull out and tune with. I was able to tune my D and G great, but when I tried my A and E, it didn’t work. The sound frequency just kept jumping, making it hard to tell if I had tuned it right. This version also is just a rip off of the premium 3 dollar one, showing all the options the other one has, but not letting you use them. I would advise giving those options for a cheaper cost, and making a single app have multiple instruments to make it more appealing to more app users. Good thing to tune with, though.
