Kalkul AURA is a new spatial audio world designed to make you feel more.

AURA detects when you have your earphones connected and starts playing automatically. AURA will pause when you take your earphones out.

AURA opens right into your disc view. You can build your AURA by layering many discs on top of each other. Swipe up or tap the layer button on the bottom to fine-tune your AURA Discs.

Tap the top disc icon or swipe down to discover more AURA Discs. Discover a growing catalog of unique spatial audio content.

Leave your AURA running in the background and continue with your other apps. Your AURA will always be there when you wear your earphones.

Another future is possible.

Reality massively enhanced

Love this app. Gracefully designed UX and graphics and super cool audio tech that makes reality come alive in new ways. Have been living working with poetry readings in this new audio hologram mode.

(I’m using it with new AirPod pros btw)
