Chet vs SightSing

Chet is a free iOS and macOS app for ear training and music theory. A guided learning path supports self-paced study, alongside a library of musical games. Exercises cover intervals, scales, arpeggios, chords, progressions, tonal sequences, famous tunes, and atonal sequences. Responses can use piano, guitar, bass, or multiple choice, and MIDI compatibility allows a MIDI keyboard. Practice Mode uses spaced repetition. Users can sign in to track progress and compete with musicians worldwide. The plan is listed as free, with no paid price or usage limit stated. Chet’s privacy policy says the app collects in-app activity such as exercise data and may transmit it to cloud storage. It is not intended for children under 13, and absolute data security cannot be guaranteed. Privacy questions and deletion requests go to [email protected].

SightSing provides sight-singing practice with real-time microphone feedback and an 18-level curriculum. As you sing, each note is marked hit, miss, or off by a half step. Separate sight-singing, rhythm, and interval trainers track progress independently, with adaptive difficulty available. Each level introduces one concept and uses rolling-window mastery, so a missed day does not reset progress. The Free plan costs nothing, covers Levels 1–3, and requires no credit card. Monthly costs $4.99 a month; Annual costs $49 a year. Both paid plans include all 18 sight-singing levels, the rhythm and interval trainers, real-time feedback, practice streak and history, and cancellation anytime. Visitors can try a sample melody without signing up. Microphone audio is processed on the device and not recorded or transmitted; only the score is saved. Pitch accuracy depends on the device, microphone, ambient noise, and singing volume. SightSing is for ages 13 and up and is not a classroom product.
