3.0.0
July 20, 2026
Coco 3.0 is the biggest update since launch. Here is what changed. A WHOLE NEW LOOK We redesigned the entire app: bold colors, high contrast, and a cleaner layout that puts your daily training front and center. Every skill family now has its own color, so you always know what you are working on. ASSESSMENTS Three new tests measure your ear: pitch acuity, relative pitch, and absolute pitch. Take them anytime to see where you stand, and retake them as you improve. Pro members unlock the full report and history. A NEW PITCH GAME The pitch game is now a tuner. Listen to the target tone once, then drag the ruler until your tone matches it. One listen, one answer, all ear. THEORY LESSONS, REBUILT Lessons are now swipeable slides with interactive piano and staff diagrams you can tap and hear. Quizzes let you retry until you get it right, so you move on only when the concept is truly yours. A NEW "ME" TAB Your stats and profile now live in one place: streak, accuracy, and your progress over the last 7 or 30 days, all at a glance. LEADERBOARD A new podium design, and your row stays pinned on screen no matter where you rank. ITALIAN AND SPANISH The app is now fully available in Italian and Spanish. AND MORE - New results screens after every game, lesson, and daily workout - Games start with a quick countdown instead of an extra screen - Exercises and levels load noticeably faster - Smaller download size - Many small fixes and polish throughout If you enjoy training with Coco, a review helps more than you know. Thank you.
