Sparkler: Japanese Fireworks

Sparkler brings senko hanabi — the delicate Japanese sparkler — to the palm of your hand.

Touch the screen to light it. Sparks crackle and shift through the four traditional phases, from the first bloom to the quiet fall of the last ember.
No fire, no smoke, no season. Take a slow breath at the end of a busy day.


REALISTIC SENKO HANABI
- Faithfully recreated phases, from ignition to the final ember
- Every burn is slightly different — no two sparklers are ever the same
- Traditional styles included: Subote botan (western Japan) and Nagate botan (Kanto)
- Colorful variants like jade, lapis, and gold

LIGHT IT IN YOUR OWN SCENERY
- Camera background: hold the sparkler against the world in front of you
- Switch between the rear and front camera

RECORD EVERY BURN
- Turn on recording and each sparkler is captured from ignition to the end
- Rewatch in the gallery, save favorites to your photo library
- Perfect for sharing on social media

FEEL IT WITH ALL YOUR SENSES
- Crackling sparkler sound
- Ambient sound: sparks subtly react to the sound around you (with mic permission)
- Tilt: tilting your phone changes the way sparks fall
- Haptics: feel each burst in your hand

PERFECT FOR
- Winding down before sleep
- That late-summer night when you want one more sparkler
- Places and seasons where real fireworks aren't an option
