# Secret Diary vs AI找图

The clearest difference is in-app purchases: AI找图 at none against Secret Diary's 1. AI找图 also leads on update cadence (every 3 weeks vs every 3 months) and iOS requirement (13.0 vs 15). Secret Diary's advantage is device support (4 vs 2). On price and ads there is nothing between them.

Both are free to download. Secret Diary sells 1 one-off in-app purchase. AI找图 asks for nothing beyond the download.

Secret Diary ships an update every 3 months, AI找图 every 3 weeks. The most recent releases landed on October 7, 2026 and October 10, 2026 respectively.
