Ratings and reviews

I've used some version of this app on my desktop, laptops, tablet, and phone. The pay version is worth the price because of the features. I like this because it's simpler to choose the note you want. I am a bassist. I also play guitar, violin, and banjo. This will work with all of them! You should remember that it's not plugged in so you need a quiet place. I use an electronic tuner on stage so I can plug in. I don't think this has option to plug in. Hint!

This is an excellent tuner. The display is clear, accurate and easy to read. I have used many tuners over my 50 years of playing and performing. I use it for tuning a wire strung harp. The adjustments of the "in tune" range to .5 cents that is available in the paid version are very useful. I also appreciate that the display changes color when a string is within the range. I will definitely recommend it to other musicians
