Complete Ear Trainer vs SightSing

Complete Ear Trainer is an app for practicing relative pitch, aural skills, and music theory for activities such as improvisation, composition, singing, and playing in a band. Its material spans 11 drill types, including 24 intervals, 36 chord types, inversions, 28 scale types, melodic dictations, and chord progressions. Classic mode has 150+ progressive drills across four levels and 28 chapters; Easy mode has 50+ drills across 12 chapters and is designed for beginners. Chapters include theory cards, and the maker says staff-reading knowledge is not required. Users can create and save custom drills or training programs for friends and students; teachers can add weekly drills and view scores on private leaderboards. Audio includes five octaves of recorded grand piano and seven additional recorded sound banks. The app also has achievements, global leaderboards, and chapter progression. Mobile downloads are listed for several app stores; desktop and browser use is included in Complete Music Trainer. Free access covers the first chapter of each mode. The full version costs $6.99, paid once, with price variation possible by country, taxes, and store.

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.
