Proof.

Proof is an iPad-native, Apple Pencil–first contact sheet. Lay out a shoot as a grid. Mark it up the way you'd mark up a real proof — wax-pencil ticks, circles, crossed frames, notes in the margin. Write print-development notes by hand. Then export the marked-up sheet alongside the original RAWs so it sits in your Lightroom or Capture One filmstrip as a visual reference while you develop.

One-time purchase. No subscription. No AI culling. No suggestion engine deciding which frames matter. The act of looking is the point.
