# Calculator vs PDF Bookmark Gen

The clearest difference is ads: PDF Bookmark Gen at none against Calculator's shown. Calculator's advantage is update cadence (daily vs weekly) and iOS requirement (12.0 vs 16.0). On price, in-app purchases and device support there is nothing between them.

Both are free to download. Calculator sells 1 one-off in-app purchase and PDF Bookmark Gen sells 2 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.

Calculator ships an update daily, PDF Bookmark Gen weekly. The most recent releases landed on October 30, 2026 and October 25, 2026 respectively.
