Sequencer 02

Sequencer02 is a small music sequencer for composing your own loop: a 4-bar pattern (32 eighth notes) with piano, bass and drums. Pick an eighth note in the grid, then lay down a piano note, a bass position or a drum (hi-hat, snare, kick). Press Play to hear your groove loop round, and set the tempo as you like. Three instruments: piano, bass (bass guitar neck) and drums. A set chord grid to practise placing the right notes. Score and mark out of 10: notes that belong to the chord, steady drums and a groove that really "turns" earn points — ideal for working on rhythm and harmony. Note names as you like, in French (do re mi) or in English (a b c), sharps or flats (C / D). Real sounds, gentle feedback, sound and vibration settings, built-in tutorial. Perfect for a first taste of composition, rhythm and note reading in music lessons, in music theory classes, at music school or at a conservatoire — or simply for the pleasure of inventing a piece. Completely free, with no advertising and no in-app purchases. Part of the Lusique collection of music games.

Verdict
The clearest difference is price: Sequencer 02 at Free against Chord's $3.99. Sequencer 02 also leads on update cadence (every 6 days vs every 4 weeks). Chord's advantage is device support (5 vs 3). On ads, in-app purchases and iOS requirement there is nothing between them.
