Karunattu

The only Carnatic music app with real-time pitch detection across all 22 Indian microtones (śrutis), an authentic 11-instrument synth engine calibrated against historical recordings, and a full studio for composing your own kritis.

WHAT EVERY USER GETS (FREE)
• Tune — pick your Sa and start the tampura drone in any of 23 semitones. The drone follows you across every screen.
• Learn — 72 melakarta rāgas with audio examples: hear the ārōhaṇa/avarōhaṇa, see the swaras on a 22-śruti grid, and learn how parent rāgas relate to their derivative janya rāgas.
• Ask the Guru — plain-language answers about rāgas, tālas, gamakas and śrutis, sourced from Karunattu's own verified library and always naming the source. No generative AI.
• Practice — Sarali varisai and free instrument practice (veena, violin, mridangam) with real-time cents feedback on every swara. Carnatic-aware, not 12-TET.
• Compose — the Compose Studio arranges your own phrases: choose a rāga, a tāla, an instrument; generate; export to MIDI.
• Track — practice streaks, XP, and the Riyāz Journal.

KARUNATTU PLUS — FOR THE SERIOUS STUDENT
• Voice Coach — sing any 8 notes; get 29-doṣa feedback (Sangeet Parijat voice analysis) tuned to your voice's natural temperament.
• Doṣa Coach — live pitch accuracy, vibrato, nasality, breathiness, and phrase-shape fault detection while you sing freely.
• Advanced Tuner — live cents feedback anchored to your saved Sa.
