AirWrite vs BMC Convention

Write your own text in mid-air with your iPhone! Type a message, press GO, hold the phone up and wave your forearm like a windshield wiper. AirWrite tracks the motion of your arm and keeps the letters frozen in the air — your message hangs in space as if painted with light. A creative way to say HELLO at a concert, cheer someone from the crowd, find your ride at the airport, or just amaze your friends in the dark. You will definitely catch attention! HOW IT WORKS AirWrite models your arm as a compass: your elbow is the centre and the phone draws on the arc your hand traces. Motion sensors follow every swing with zero drift, so the text stays exactly where you "hung" it — even during fast waves. Letters curve along the arc, just like your hand moves. SMART BY DESIGN • No calibration — physics measures your arm length automatically while you wave • Feel a gentle tap when you reach the beginning and the end of your message • Double-tap to re-centre the text anywhere you like • Adjustable text size, remembers your message and colour • Works fully offline, nothing to sign up for MADE FOR THE DARK The display is pure black with nothing but your glowing message — perfect for night events, parties, and festivals. PRO COLOURS Writing in classic red is free forever. Unlock the full colour wheel once and paint the air in any colour you like — the purchase is yours for good and restores on any of your devices. Take your phone, enter the text, and wave!
