Everything for daily riyaz
One app, the whole baithak
Real instrument samples, the taals and raags you actually practise, and tools to write down and record what you play.
Tabla
49 taals, 100+ style variations, 25–300 BPM, with pitch, scale and volume control. Five taals are free, the rest with Premium.
Tanpura
A continuous drone with Pa, Ma or Ni tuning, in any scale, at any volume. Runs alongside every other instrument.
Harmonium
36 keys across 3 octaves with raag-guided key highlighting and meend glides. Sur Peti for a steady shruti.
Raag practice
117 raags with aaroh, avroh, pakad and alaap that play note by note, in Bhatkhande notation, over a matching tanpura.
Notation
Write Bhatkhande notation with Devanagari swar, or point the camera at a printed sheet and let the app read it — taal-aware.
Studio
Record over your accompaniment with a waveform editor and beat markers, choose which instruments to capture, export AAC.
Compose and record
Write the bandish, set each section, press record
Build songs in sections — sthayi, antara and more — each with its own taal, tempo and instruments. Add lyrics and notation, then record your voice over the accompaniment and export a clean AAC mix.
