Etüdra helps musicians plan focused practice sessions, stay on tempo with a built-in metronome, keep in tune with a built-in tuner, and track BPM progress over time. PLAN WHAT TO PRACTICE Build programs from sections — scales, rhythm, ear training, technique, whatever you're working on. Break each section into focused exercises, each with its own target BPM and minimum duration, so every minute has a purpose. STAY ON TEMPO A built-in metronome runs through every exercise with count-in, tap-tempo, subdivisions, and accents. Nudge the tempo in 5-BPM steps, or press and hold to jump by 10. SEE MEASURABLE PROGRESS Etüdra logs the actual BPM you hit on every exercise, so you always know where you left off. A calendar heatmap shows your weekly minutes, week-over-week comparison tells you whether you're trending up, and per-block history keeps your recent attempts. TUNE WITHOUT SWITCHING APPS Tune before you start, or pause mid-session and open the chromatic tuner. No app-switching, no lost focus. SHARE ONLY WHEN YOU CHOOSE Post session summaries to followers, choose the audience, or keep everything private. Three privacy tiers — public, followers-only, or strict private. One-tap kudos. USE ETÜDRA FOR Daily scales, technique drills, rhythm work, lesson assignments, repertoire practice, or focused free-time sessions. Free Time mode skips the block structure and simply times your practice, with the metronome and tuner one tap away. From scales and technique to rhythm work and repertoire, Etüdra turns practice time into measurable progress — built for guitarists and other instrumentalists.
