Train your ears like a pro musician, in minutes a day. Pitch Master listens to how YOU hear. The more you train, the more it learns your ear's strengths and weak spots, then builds daily exercises that target exactly what you need to improve. No generic drills, just focused, adaptive training. WHY PITCH MASTER Personalized training: Every exercise adapts to your ear. Struggling with certain intervals or notes? Pitch Master notices and focuses your practice there, so you improve faster. Real ear training, not guesswork: Build genuine pitch recognition and relative pitch skills through structured, research-backed exercises, not random quizzes. Track your progress: Watch your accuracy improve session by session, with clear feedback on which notes and intervals you've mastered. Bite-sized daily practice: Sessions are short and focused, so you can build a real habit, even on your busiest days. WHO IT'S FOR Whether you're a singer, instrumentalist, producer, or just musically curious, Pitch Master helps you develop the ear training foundation every musician needs: pitch recognition, interval recognition, and relative pitch.

Verdict
The clearest difference is in-app purchases: TRN Go at none against Pitch Master's 5. TRN Go also leads on rating (5.0 vs 4.6) and device support (3 vs 1). Pitch Master's advantage is update cadence (daily vs every 7 months) and ratings volume (640 vs 2). On price and ads there is nothing between them.
