# Math Keyboard For Equations vs Comet

The clearest difference is price: Comet at Free against Math Keyboard For Equations's $0.99. Comet also leads on ratings volume (7.8K vs 8) and rating (4.8 vs 4.6). Math Keyboard For Equations's advantage is in-app purchases (none vs 3) and update cadence (every 2 days vs weekly). On review sentiment, ads and device support there is nothing between them.

Comet is free to download; Math Keyboard For Equations costs $0.99 up front. Comet sells 3 in-app purchases, starting at $20.00 per month. Math Keyboard For Equations asks for nothing beyond the download.

Comet holds the better App Store score, 4.8 against 4.6. That said, the two scores are not equally well evidenced: Comet has 7.8K ratings behind it against 8, so its average is the more settled of the two. Written reviews complicate that: 67% of Math Keyboard For Equations's written reviews are positive against 65% of Comet's, so the app with the better star average is not the one people write more warmly about.

Math Keyboard For Equations ships an update every 2 days, Comet weekly. The most recent releases landed on September 19, 2026 and September 24, 2026 respectively.
