SOLFIO 88 · 4/5 · 🔥 21-day streak — "the tritone got me again"
Interval recognition is the foundation of relative pitch — and the part of aural-skills class everyone procrastinates. Solfio turns it into a two-minute daily ritual with a streak worth protecting. Your stats screen tracks accuracy per interval, so when the tritone beats you three days running, you know exactly what to drill.
Roots span two octaves in a warm piano timbre. Later rounds go harmonic — notes together — the way exams and real music actually sound. Solfio Pro adds unlimited practice sets targeted at your weakest intervals.
