Complete Music Reading Trainer is an app designed to help users learn to read sheet music and improve their sight-reading skills. The app is designed like a video game and offers 270 progressive drills covering all seven clefs over three levels and 26 chapters. Users can choose which levels or chapters are relevant to their instrument and focus on those. The app also offers practice for key signatures up to 6 sharps/flats in progressive key signature drills and common clef combinations in mixed clef drills.

The app offers a selection of 19 drills in arcade mode and 5 octaves of actual recorded grand piano sounds. Users can input notes in four ways: note circle, virtual piano keyboard, by connecting a MIDI controller, or by playing an instrument near the device's microphone. The app also offers four sheet music display styles: modern, classic, handwritten, and jazz. Users can earn 3 stars in each drill of a chapter to complete it or try to obtain perfect 5-star scores.

Users can create and save their own custom drills and rehearse them at their convenience. They can also create full custom training programs and invite friends or students to join them. The app offers cloud sync across various devices, Google Play Games achievements to unlock, leaderboards to compare arcade mode scores with other players worldwide, and global statistics to track progress. The app is designed by a musician and music teacher with a Royal Conservatory master's degree.

The app is available for free download, and users can try out the first chapter of each clef for free. To unlock the full version on all Android devices, users can make a one-time in-app purchase of $3.99. If users have any problems or suggestions, they can reach the app's team at [email protected] .
