# PCalc vs ConvertCalc

The clearest difference is price: ConvertCalc at Free against PCalc's $9.99. ConvertCalc also leads on update cadence (every 8 days vs every 6 weeks) and rating (5.0 vs 4.7). PCalc's advantage is ads (none vs shown) and ratings volume (770 vs 2). On in-app purchases and monetization model there is nothing between them.

ConvertCalc is free to download; PCalc costs $9.99 up front. PCalc sells 4 one-off in-app purchases and ConvertCalc sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.

ConvertCalc 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 2, so its average is the more settled of the two. Written reviews point the same way: 84% of PCalc's written reviews are positive against 100% of ConvertCalc's.

PCalc ships an update every 6 weeks, ConvertCalc every 8 days. The most recent releases landed on September 24, 2026 and September 18, 2026 respectively.
