Clefira vs Earz

Clefira provides music practice for interval and chord exercises, sight reading, piano-note recognition, and teacher-guided drills. The free Student edition offers interval practice with three answer choices and scored sessions, alongside chord work covering major, minor, augmented, diminished, suspended, and seventh chords. In sight-reading exercises, students identify treble- or bass-clef notes using a mini keyboard and receive immediate visual feedback. Sessions include lives, streaks, XP, scoring, replay, slow mode, restart and go-back controls, and summary overlays. The Student edition is aimed at learners age 13 and older and adult learners, and is listed for Windows, Android, and web. Windows requires version 10 or 11, 64-bit is recommended, and ear-training playback requires speakers or headphones. Clefira describes the Android Student app as self-contained, with no sign-in, cloud sync, or internet access. Practice and profile data stay local by default; the maker says it has no analytics, trackers, or ads. Optional microphone and MIDI input are processed on-device and not transmitted. Cloud sync is opt-in. A paid Teacher edition is planned, but checkout and license delivery are not enabled.

Earz teaches ear training, note reading, music theory and music knowledge through online games for different levels and ages. It includes dozens of standard games that teachers can copy and edit, as well as tools to create new activities with their own text, links, images, sound and YouTube videos. A Quiz module supports custom questions in several formats, and an AI assistant can assess open-ended answers; the maker labels that feature beta. Teachers can view student results in an online tracking system. Earz is described as suitable for primary and secondary schools, private music schools, bands and choirs. School subscriptions are priced yearly by participant capacity: plans range from Earz School 20 at €35 a year to Earz School 2500 at €695 a year. Earz Solo is listed at €999 a year for unlimited Android and iOS use. A free plan and a 7-day trial are available. The service runs on web, Windows, macOS, Android and iOS, but requires an internet connection. The maker says personal data is processed under GDPR, sent over SSL and stored encrypted on a central server in Frankfurt, Germany.
