Swar Detector

Sing a note. See the swar. Swar Detector listens to your voice or instrument and shows you the note you are on — big, clear, and instant. A ring around it turns from amber to green as you close in on true pitch, and bursts gold the moment you lock it. BUILT FOR RIYAZ Set your Sa to any key and octave, and every swar on screen re-maps to it. Practice in your own scale, the way you actually sing — not someone else's. सा रे॒ रे ग॒ ग म म॑ प ध॒ ध नि॒ नि The full twelve-note rail sits along the bottom, with your current note lit. Read it in Devanagari, or switch to Western names (C, D, E…) with one tap. SEE HOW CLOSE YOU ARE A live cents reading tells you exactly how sharp or flat you are — so you can hear the difference and fix it, note by note. FOR SINGERS AND PLAYERS Voice, harmonium, flute, sitar, guitar, violin — anything with a clear pitch. Useful for daily riyaz, for tuning, and for training your ear. QUIET AND PRIVATE No account. No ads. No network. Audio is analysed on your device and thrown away immediately — nothing is ever recorded, saved, or uploaded. Set your Sa and begin.

Verdict
The clearest difference is price: Swar Detector at Free against Droon's $2.99. Droon's advantage is iOS requirement (15.0 vs 17.0). On ads, in-app purchases and device support there is nothing between them.
