Souffly

Birthday candles, party horn, and pinwheel that respond to your breath in real time. No account, no data sent — everything happens right on your phone.

Really blow into your phone to blow out birthday candles, unroll a party horn, or spin a pinwheel — Souffly turns your phone's microphone into magic breath.

THREE WAYS TO BLOW

Birthday Candles Pick the age, the number of candles (up to 99), add a photo and a name, then blow for real. Candles go out gradually, with confetti and balloons at the end.

Party Horn Blow to unroll the horn's tongue with its signature "vzzzzzt" sound. Multiple horns can unroll in cascade — perfect for a party with friends.

Pinwheel A 6-blade pinwheel that spins at the speed of your breath, with real inertia — it slows down gradually once you stop.

SIMPLE, NO ACCOUNT NEEDED No sign-up, no data sent to a server: Souffly runs entirely on your phone. Microphone audio is never recorded or saved, just analyzed to detect your breath.

SHARE THE MOMENT Capture or film the moment and share it straight to Messages, WhatsApp, or Instagram.

Perfect for a birthday, a party with friends or family — at home or on the go, no real candles or party horn needed.
