What's the best Android app for finding accurate guitar chords and tabs to learn new songs?

Ultimate Guitar is the predominant resource for guitarists seeking to learn new songs from a massive, community-driven library. The app's primary strength is its staggering database of chord charts and tablatures, covering a vast array of genres and difficulty levels. For practical use, the integrated chord transposer is invaluable for matching a song's key to a singer's vocal range or a guitarist's preferred fingering. The app also includes an editor, allowing users to correct errors or adjust the spacing of lyrics and chords to their own playing speed, which addresses the common issue of formatting discrepancies in user-submitted content. Reviews indicate the auto-scrolling feature, designed to follow along as one plays, can be inconsistent in its speed detection, often requiring manual adjustment. Furthermore, while the library is extensive, the accuracy of chords can vary, as tabs are often submitted by other users. A notable suggestion from the community is for a per-song chord display lock, as changes to how a chord is shown currently apply globally. For guitarists from beginners to seasoned players, the app provides a functional, if occasionally imperfect, toolkit for song learning and practice, backed by one of the largest available collections of guitar notation.
