ChordWeave vs JazzTree

ChordWeave is a chord progression and songwriting app for iPhone and iPad. Pick one of 24 keys and a mood to hear a chord progression instantly, play a keyboard and have ChordWeave name your chords, and write lyrics with Apple Intelligence. It runs on your device, with no account. HEAR A PROGRESSION INSTANTLY ChordWeave opens on the Composer with a playable progression ready. Pick any of 24 keys and a mood, tap Generate, and hear it right away. Where Apple Intelligence is available, it refines the result on your device. Reorder chords, hear each one, and see its notes. ADD TO A SONG (PRO) Turn a progression into a Song Project: arrange intro, verse, chorus, bridge and more, reorder the sections, and play the whole song. Try a playable sample project first. WHY IT WORKS (PRO) Get a short theory explanation for each progression, tied to its chords, so you learn why it sounds the way it does. PLAY & NAME CHORDS Play on the on-screen keyboard or a connected MIDI keyboard and ChordWeave names the chord. Build a progression by playing, then get suggestions for what comes next in pop, jazz, blues and more. Includes a metronome. Listen for Key (iOS 27) detects the key and tempo from a few seconds of playing or singing. LYRIC WRITING With Apple Intelligence, write verses, a chorus and a bridge for your mood, theme and style. Edit and save them in your library. EXPORT Share a progression as a picture card (chords, key and tempo), export it as a MIDI file for your DAW, or share it as text. MADE FOR iPAD A native iPad app in every orientation, with two-column layouts that use the whole screen. MUSIC THEORY REFERENCE Scales and modes in every key, the chords of each scale with Roman numerals, and common progressions. SIRI & SHORTCUTS Ask Siri for a chord progression, or see your recent compositions, without opening the app. Saved compositions also appear in Spotlight search. PRIVATE BY DESIGN Apple Intelligence features run entirely on your device, and your songs are never uploaded to a server. Without Apple Intelligence, ChordWeave uses built-in music theory instead. No account. No tracking. No ads. FREE AND PRO Free: play and chord naming, the Composer, single-progression MIDI and text export, lyrics, music theory, Siri, and up to 3 saved compositions and 3 saved lyric sets. ChordWeave Pro: unlimited saves, Song Projects and Why it works. Choose Annual, Lifetime, Monthly or Weekly. COMMON QUESTIONS Does ChordWeave identify chords from a song or recording? No. It names the chords you play on the on-screen keyboard or a connected MIDI keyboard. Listen for Key (iOS 27) detects the key and tempo from a few seconds of playing or singing, not the chords. Is it free? You can start free: chord naming, the Composer, lyrics, music theory, MIDI and text export, and up to 3 saved compositions and 3 saved lyric sets. ChordWeave Pro adds unlimited saves, Song Projects and Why it works. Do I need Apple Intelligence? No. Progressions and chord naming use built-in music theory.
