Ten shapes, one per finger — raise a finger to include its shape. Twist a hand to turn the colour wheel, tilt it forward or back to reorder the shapes, two hands to resize. Hold a shape still for four seconds and it saves itself.

Ten shapes — tap one to put it in your sigil, tap again to take it out, double-tap for a different shape. Set the colour and the size, then save it. No camera needed.

You are not signed in. A sigil you save now joins the gallery for real, saved as created anonymously: it belongs to nobody and will not be waiting for you. Sign in to keep the ones you make.
