★ Flagship

SUS4 Practice turns practice into a game you play on your real instrument. There are 250 levels across 25 themed worlds, each ending in a boss level, and six game modes that listen through the mic as you play: Pitch Jumper, Arpeggio Maze, Interval Invaders, Rhythm Runner, Technique Drill and Finger Independence.

Available on iPhone, iPad, Mac and Apple Watch. Alongside the game there is a Learn tab with step-by-step lessons for 15 instruments that tracks your mastery of each one, a daily routine, achievements and Game Center leaderboards, plus Jazz, Latin, Metal, Blues and Classical level packs that add 50 levels each. On Apple Watch, quick interval, chord and scale ear drills get harder as you improve and show the day streak from your phone.

A Journal tab lets you log the pieces you are working on, record each session's length and tempo, and climb a tempo ladder towards your target speed. The game gets you to pick up the instrument; the journal shows whether the work is adding up.
