Inspired by Op Art of the 1960s, OpEvol takes the geometric play of colors and contrasts and animates them into a moving field of ever-changing, optical, kinetic abstraction. It's for staring at. It's for sending to Air Display. Or an external monitor. Or a projector. It's something mesmerizing to design and watch evolve, or just leave on in the background as art. OpEvol Pro is an auto-renewing annual subscription (price shown in the app). Payment is charged to your Apple ID at purchase, and it renews automatically unless canceled at least 24 hours before the end of the period. Manage or cancel anytime in your Apple ID settings.
