Verdict
The clearest difference is price: Bookmarks at Free against PCalc's $9.99. Bookmarks also leads on rating (5.0 vs 4.7). PCalc's advantage is ratings volume (770 vs 12) and update cadence (every 6 weeks vs every 4 months). On ads, in-app purchases, monetization model and device support there is nothing between them.

Bookmarks is free to download; PCalc costs $9.99 up front. PCalc sells 4 one-off in-app purchases and Bookmarks sells 4 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.
Bookmarks holds the better App Store score, 5.0 against 4.7. That said, the two scores are not equally well evidenced: PCalc has 770 ratings behind it against 12, so its average is the more settled of the two. Written reviews complicate that: 84% of PCalc's written reviews are positive against 75% of Bookmarks's, so the app with the better star average is not the one people write more warmly about.
PCalc ships an update every 6 weeks, Bookmarks every 4 months. The most recent releases landed on October 3, 2026 and September 27, 2026 respectively.
