ai is bored. it has seen 5 million sunsets. 3 million lattes. infinite selfies. can you surprise it? no filters. no likes. just you versus the algorithm. 3 shots a day. point your camera at anything. the AI scores what it sees 0-100 on rarity - from common to ultra rare. enter the daily pool. beat your friends. beat the world. the highest rarity wins. be rare.

Verdict
The clearest difference is in-app purchases: RedSum at none against proof's 6. proof's advantage is update cadence (every 9 days vs every 5 weeks) and iOS requirement (18.2 vs 26.0). On price, ads and device support there is nothing between them.
