Hi Organ

Hi Organ turns your iPhone or iPad into a real arranger keyboard - the kind of instrument where you hold a chord with your left hand and a complete backing band plays along with you.

WHY HI ORGAN

Most keyboard apps give you a piano and stop there. Hi Organ gives you the whole instrument: four keyboard parts, an auto-accompaniment engine with eight independent tracks, a mixer, effects, drum pads, and recording. Everything you would expect from a hardware arranger is brought together in one app, with controls arranged in a familiar, performance-focused layout.

Hi Organ is also designed to feel at home on the latest Apple devices. On iOS 26 and later, the app features a dedicated Liquid Glass interface with translucent panels, layered depth, soft reflections, dynamic highlights, and responsive glass-style controls. The result is a cleaner, more immersive workspace that keeps important performance controls easy to see while giving the instrument a distinctly modern iOS look.

Whether you are practicing, arranging, performing, or simply exploring new sounds, Hi Organ combines the depth of a full arranger keyboard with a visual experience built for the newest generation of iOS.
