Harmonomics vs SightSing

Harmonomics has no write-up on Specifiction yet; its figures are above.

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.
