EarBattle
Music Theory Speed Challenge
$0.99 · Designed for iPad. Not verified for macOS.
Real-time ear-training duels. Race a friend — or the bots — to identify intervals, chords, scales, and progressions before they do. Fastest ear wins.
Think you have a good ear? Prove it — in real time, against someone else.
EarBattle is a head-to-head ear-training duel. You and your opponent hear the exact same sequence of 10 questions — intervals, chords, scales, or chord progressions — and race to identify each one correctly before your rival does. Speed and accuracy both count.
REAL-TIME 1v1 DUELS
Matched instantly through Game Center, you and your opponent get the same questions at the same moment, generated from a shared seed so nothing has to stream over the network — just pure, low-latency competition. Watch your rival's status update live: thinking, answered, right, or wrong.
SCORING THAT REWARDS BOTH EARS AND SPEED
• Correct answer: 100 points
• Speed bonus: up to +50 points the faster you answer
• Streak bonus: up to +50 points for consecutive correct answers
• Wrong or no answer: 0 points, and your streak resets
PRACTICE SOLO, NO ACCOUNT NEEDED
Not ready to duel a real person? Practice against the app itself, with three bot difficulty tiers — Beginner, Music Lover, and Virtuoso — each with its own accuracy and reaction speed. Works fully offline.
BOT LADDER TOURNAMENT
Take on all three bots back-to-back in a single run. Your score and wins carry across all three rounds for one combined result — sweep the ladder for a perfect run.
WHAT YOU'LL TRAIN
• Intervals — from unisons to octaves
• Chord qualities — major, minor, diminished, augmented, 7ths, and more
• Scales and modes — major, minor, modal, pentatonic, blues, and more
• Chord progressions — common functional progressions by ear
Whether you're a music student, a working musician, or just someone who wants to sharpen their ear the fun way, EarBattle turns practice into competition — no textbook required.
