Improve your ear for tuning and general intonation with tuneUp Lite - Intonation Ear Training Game. This iPhone app is designed to help users enhance their ear training skills, from easy to expert levels. Compete with people from around the world and track your progress through GameCenter.

The gameplay of tuneUp Lite is simple yet effective. Press the "1" button to hear a pitch, and then press the "2" button to hear the same pitch slightly out of tune. If the "2" pitch is sharp, press the sharp button. If it is flat, press the lower button. Be careful, as you only have three lives. However, if you achieve a high score and want to continue playing, you have the option to purchase an extra life.

Tuning is a crucial skill for musicians, and tuneUp Lite helps you develop your ear for accurate intonation. The app provides piano samples for free, and you can expand your instrument options by purchasing guitar, flute, and marimba samples through in-app purchase.
