SightSing vs Trill

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.

Trill offers ear-training practice for musicians who want to recognize musical sounds by listening. Exercises include chord recognition, interval identification, melodic dictation, pitch memory, and chord progressions, with practice covering pitch, melodies, scales, and theory. A structured path adapts to a learner’s goal and level; the maker recommends focused sessions of about 10 minutes a day. Daily challenges, streaks, levels, XP, and collectible badges encourage regular practice. Focus Lock can block TikTok, Instagram, and YouTube until the daily training is complete, with correct answers earning break time. The free plan includes a tuner, metronome, chord, interval, and scale visualizers, plus limited ear-training access. Trill Pro costs $59.99 per year after a 7-day free trial and adds unlimited training, advanced exercises, progress tracking, achievements, and Focus Lock. Trill is available on Android, iOS, and the web. The iOS listing requires iOS 14.0 or later; it also lists iPad, Apple Vision, and Apple silicon Mac compatibility, with macOS 11.0 or later for Mac.
