TuningEar Light is a limited version of TuningEar, which is also available from the App Store.
TuningEar allows you to train your ears to hear the difference between "in tune" and "out of tune".
Of course, practice is the best teacher, but you can't always carry your music instrument around, so TuningEar assists you to exercise in those "lost" moments when your instrument is at home.
TuningEar works by letting you hear two notes. It's up to you to decide whether they are in tune or not.
The full version offers these additional features:
-Higher difficulty settings
