Create together with ARStain, an AR drawing experience for children and parents. Choose a Bird or Car and place it in the live AR view. Move and resize it to explore. For Birds, move the colorful AR Bird aside to reveal its sketch. The sketch guides your drawing; the color Bird gives you a visual reference. Switch to Draw and make your picture with a finger. Return to AR to check the sketch or color reference, then keep drawing. When you're ready, save your drawing to Photos. The saved image contains only your drawing, not the camera view, AR objects, or app controls. Hummingbird and all Cars are free. A one-time, non-consumable Premium in-app purchase unlocks nine additional Birds; it is not a subscription. If you purchased Premium before, open a locked Bird and choose Restore Purchases.
