# Liner vs MathAce

The clearest difference is rating: MathAce at 4.7 against Liner's 4.4. MathAce also leads on review sentiment (59% vs 39%) and ratings volume (8.8K vs 1.4K). Liner's advantage is update cadence (every 8 days vs every 2 weeks). On price, ads, in-app purchases and monetization model there is nothing between them.

Both are free to download. Liner sells 18 in-app purchases, starting at $9.99 per month and MathAce sells 3 in-app purchases, starting at $6.99 per 7 days. Whichever you choose, the download price is not the number that matters.

MathAce holds the better App Store score, 4.7 against 4.4. That said, the two scores are not equally well evidenced: MathAce has 8.8K ratings behind it against 1.4K, so its average is the more settled of the two. Written reviews point the same way: 39% of Liner's written reviews are positive against 59% of MathAce's.

Liner ships an update every 8 days, MathAce every 2 weeks. The most recent releases landed on October 22, 2026 and October 23, 2026 respectively.
