Sound That Understands You
Ambient Sound Library
Rain on a tin roof, ocean waves, temple bells, café chatter, forest sounds, lo-fi beats. Twenty-five built-in tracks across five mood categories. No subscription, no in-app purchases.
Voice-Controlled Playback
"Play rain sounds" or "something for studying" — Sathi picks the right track. Pause, skip, or change with voice. No need to touch the screen or navigate any interface.
Sleep Timer
"Stop music in 30 minutes." Sathi fades out gradually so you drift off naturally. Set it by voice during any conversation — no separate timer app needed.
Mood-Based Suggestions
Sathi knows your mood from your conversation. Feeling stressed? It suggests calming sounds. In a focused zone? Lo-fi beats. The music adapts to your emotional state automatically.
