# PinNotes vs 收藏庫

The clearest difference is iOS requirement: 收藏庫 at 13.0 against PinNotes's 17.0. On price, update cadence, ads and in-app purchases there is nothing between them.

Both are free to download. PinNotes sells 2 in-app purchases, starting at $0.99 per month and 收藏庫 sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.

PinNotes ships an update every 4 days, 收藏庫 every 6 days. The most recent releases landed on October 7, 2026 and October 1, 2026 respectively.
