# Calculator++P vs Simple Calculator.

The clearest difference is price: Simple Calculator. at Free against Calculator++P's $2.99. Simple Calculator. also leads on rating (4.6 vs 4.2) and ratings volume (1.6K vs 5). Calculator++P's advantage is ads (none vs shown) and iOS requirement (13.0 vs 15.6). On review sentiment, update cadence, in-app purchases and device support there is nothing between them.

Simple Calculator. is free to download; Calculator++P costs $2.99 up front. Neither carries in-app purchases, so what you see is what you pay.

Simple Calculator. holds the better App Store score, 4.6 against 4.2. That said, the two scores are not equally well evidenced: Simple Calculator. has 1.6K ratings behind it against 5, so its average is the more settled of the two. Written reviews complicate that: 67% of Calculator++P's written reviews are positive against 65% of Simple Calculator.'s, so the app with the better star average is not the one people write more warmly about.

Both ship on a similar rhythm, roughly every 3 months. Both last shipped on October 26, 2026.
