ChordsVault vs Poly Metronome

ChordsVault is the mobile entry into the ChordsVault portal for creating, designing and sharing guitar (and other instruments) chords and songs. ChordsVault is easy to use but provides great flexibility for songs transcribers and song readers / performers. Unlike many other sites, ChordsVault lets you design chords on the fly, reuse chords between songs, share songs and chords, and transpose songs to different keys, tunings and instruments.

Poly Metronome is a precise, modern practice tool for musicians who want more than just a click. Build complex rhythms with multi-voice polyrhythms, per-beat accents, and custom subdivision patterns, then save them as presets or setlists — or drill them with Coach and Automator.
