# j4t vs MathAce

The clearest difference is in-app purchases: j4t at none against MathAce's 3. j4t also leads on iOS requirement (13.0 vs 16.0). MathAce's advantage is ratings volume (8.8K vs 10) and rating (4.7 vs 4.4). On price, update cadence, ads and device support there is nothing between them.

Both are free to download. MathAce sells 3 in-app purchases, starting at $6.99 per 7 days. j4t asks for nothing beyond the download.

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 10, so its average is the more settled of the two. Written reviews point the same way: 50% of j4t's written reviews are positive against 59% of MathAce's.

Both ship on a similar rhythm, roughly every 2 weeks. The most recent releases landed on July 16, 2026 and September 27, 2026 respectively.
