# Calculator Plus #1 vs MechMath

The clearest difference is ads: MechMath at none against Calculator Plus #1's shown. MechMath also leads on update cadence (every 4 days vs every 5 weeks) and monetization model (free vs free with in-app purchases). Calculator Plus #1's advantage is ratings volume (5.1K vs 2). On price, rating, in-app purchases and device support there is nothing between them.

Both are free to download. Calculator Plus #1 sells 7 in-app purchases, starting at $0.99 per month and MechMath sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.

MechMath holds the better App Store score, 5.0 against 4.8. That said, the two scores are not equally well evidenced: Calculator Plus #1 has 5.1K ratings behind it against 2, so its average is the more settled of the two. Written reviews point the same way: 89% of Calculator Plus #1's written reviews are positive against 100% of MechMath's.

Calculator Plus #1 ships an update every 5 weeks, MechMath every 4 days. The most recent releases landed on October 26, 2026 and October 9, 2026 respectively.
