The Vanido app bills itself as the "Duolingo for singing," and athat appears to be an accurate description. The app is meant to help newbies learn to sing via gamification. Users are encouraged to practice daily and are rewarded with experience points that can be used to unlock new exercises and track progress (you level up as you learn). What makes the Vanido app special is that it personalizes the user experience.
The Vanido app tailors lessons to your vocal range and tracks your pitch in real-time. The pitch tracking is especially useful as it allows you to make adjustments during lessons and lets you train your ears as well as your voice. The Vanido app is available now for iOS. An Android version is in the works.
