What Earsharp does

Musicians want ear-training apps that drill them. They don't want streak badges, social invites, locked content, or a login screen.

Earpeggio and Play By Ear are the dominant iOS ear trainers — and their App Store reviews are full of the same complaints: 'spamming me to invite friends', 'asks me to login every time', 'doesn't randomize intervals properly so I keep getting the same questions', 'chords can't play harmonically'.

Earsharp does the basics correctly:

— Intervals: perfect, major, minor, augmented, diminished, ascending, descending, harmonic — all six drill modes, properly random within your chosen difficulty. — Chords: triads (major, minor, dim, aug), 7ths, sus2, sus4, inversions — played harmonically (all notes together), not arpeggiated. — Scales: identify modes, major/minor/harmonic minor/melodic minor, pentatonic. — Melodic dictation: hear a 3–8 note phrase, tap the keyboard to reproduce. — Rhythm clap-back: hear a rhythm, tap it back; the app uses on-device DSP to grade.

No account. Sounds are synthesized on-device via AVAudioEngine — every drill ships in the binary. Set your daily target if you want; ignore it forever and the app says nothing. Just drills, when you open it.

Why we built it

Existing ear-training iPhone apps gamify, gate, and gate behind accounts. Earpeggio asks for login on every launch and spams friend invites; Play By Ear can only arpeggiate chords (defeating the point of harmonic chord ID); both have App Store reviews complaining about poor randomization between mastered and new mater…

What makes it different

Earsharp does five drill modes (intervals, chords, scales, melodic, rhythm) properly randomized with adjustable weighting toward weaker categories. No account, no leaderboard, no streak. Chords play harmonically with built-in AVAudioEngine synthesis. Rhythm clap-back uses on-device microphone DSP — first iOS ear-train…
