What's the best Android app for practicing guitar chords and songs without a physical guitar?

Real Guitar is an Android application that serves as a practical tool for users seeking to practice guitar chords and songs without access to a physical instrument. It features both acoustic and electric guitar simulations, complete with adjustable tunings and a chord library that displays finger positioning diagrams. This setup allows beginners to learn proper techniques and experienced players to experiment with different sounds. The app includes recording and playback functionality, enabling users to track their progress and identify areas for improvement. Reviews indicate that many appreciate the responsive touch interface and authentic sound quality, which mimic strumming and picking actions effectively. However, some users note that the free version contains ads and limited access to certain guitars, with full features available through in-app purchases. While it may not fully replicate the tactile experience of a real guitar, it remains a valuable resource for casual practice sessions, such as during commutes or breaks, helping build muscle memory and chord familiarity conveniently.
