Chordbot vs Songkeeper Studio

Chordbot is a songwriting app and backing-track generator for creating and playing chord progressions in different musical styles. It is available on Android and iOS. Its library includes more than 60 chord types in all inversions, with over 70 comping-style presets and the option to build styles from more than 400 instrument tracks. An automatic or manual inversion selector helps shape chord transitions, while repeatable song sections can each use a different comping style or arrangement. Song-O-Matic can generate progressions when users need ideas. Songs can be exported as MIDI for DAW editing or as WAV for sharing. Song files use JSON and can be shared through file-sharing apps; only JSON files can be imported back into Chordbot. Lite is free, but saving and exporting are disabled. Pro costs $4.99, paid once and enables both. The maker permits commercial use of creations in recordings and performances under a perpetual, non-exclusive, royalty-free license.

Songkeeper Studio is a songwriting app for guitarists who want to keep recordings, lyrics, chords, and practice tools together. A song can hold multiple recordings for playback and multiple drafts that can be copied, moved between songs, renamed, or deleted. Guitar tools include chord diagrams, a chromatic tuner, tuning options, and chord transposition. The writing editor offers word suggestions, rhymes, a music keyboard, tablature stamp mode, and trackpad cursor control. For practice, users can set a tempo, use a metronome or drum loops, and enable tempo-based autoscroll. Reference videos can be linked and played in the built-in YouTube player. The free Basic plan costs nothing and allows five songs, two drafts and two recordings per song. Pro costs $0.99 a month and adds unlimited songs, drafts, and recordings, Cloud Vault, sharing, collaboration, import, and export; it includes a 7-day free trial. The app runs on Android and iOS. Songs are also stored locally, and the site warns they can be lost if the app is uninstalled or the phone is lost.
