Hit That Gong

One sound. Infinite status.

Gong is a $99.99 iOS instrument that does exactly one thing: strike the gong, receive a magnificent sound. Every strike tunes to a pentatonic scale — mash it and it sings a rising melody, never a monotone. Keep striking and you unlock a collection of ten intricately-cut gemstone gongs — Amethyst, Citrine, Topaz, Jade, Onyx, Emerald, Sapphire, Ruby, Opal, and the Flawless Diamond — each with its own cut, colour, and voice. The Gong Élite upgrade ($999.99, one-time) crowns the collection in 24-karat gold. Forever.

Test the instrument

Strike the Gong — the web instrument
A faithful browser port of the app: the same synthesized 14-partial gong voice tuned an octave brighter, hold-to-strike mallet, the full gemstone collection with faceted rendering and a musical pentatonic combo, and a simulated Gong Élite purchase for testing the upgrade flow.
