Easy App to Use Professionally
Many of us (orchestral musicians and soloists) use Tuner T1 Pro because there is a lime green screen that appears when your pitch is perfect or nearly so. That lime green screen is steady, and easily seen out of the corner of your eye so that the player can make instantaneous corrections, should the screen lose its greenish glow! Even that tolerance can be adjusted for the most accurate of intonations. All of my students now use this, partly because they have Apple products, but also because it is a pleasure to use!
