HYPERBLOOM is a living garden of light that grows wherever you touch, and forgets you, slowly. There are no levels, no scores, and no goals. Just light, motion, and sound that respond to your hands. TAP to plant a seed and watch tendrils of neon light grow, branch, and burst into blooms. DRAG to bend the light and stir drifting spores into glowing comets. HOLD to charge a nova, then release a shockwave of petals and sound. Every gesture plays a note in a soft, generative score: a calm wash of plucks, sparkles, and deep booms that drift through reverb and echo. The garden quietly dissolves over time, so it is never the same twice and never asks anything of you. SEVEN MOODS Original, Bright, Somber, Dream, Dawn, Abyss, and Voltage. Each one swaps the color palette and the musical scale together, so the garden sounds the way it looks. MIRROR Turn on two, four, or six fold symmetry and every stroke you draw becomes a rosette. Your finger paints a mandala without you having to aim. KEEPSAKES Press the keep button once and Hyperbloom records the next twenty seconds of your garden, with its sound, as a movie you can share or save. Press and hold instead to keep the moment as a still image at full resolution, with no interface in it, which makes a good wallpaper. Built natively for iPhone with Metal and live synthesized audio for a smooth, glowing, endless experience. Perfect for unwinding, focusing, or simply watching light grow. No accounts. No ads. No data collected. Just you and the light.
