# Algebra vs TT Pre

The clearest difference is rating: Algebra at 4.7 against TT Pre's 3.2. Algebra also leads on review sentiment (83% vs 42%) and ratings volume (1.3K vs 109). TT Pre's advantage is in-app purchases (none vs 10) and update cadence (every 2 months vs every 4 months). On price, ads, device support and iOS requirement there is nothing between them.

Both are free to download. Algebra sells 10 in-app purchases, starting at $9.99 per month. TT Pre asks for nothing beyond the download.

Algebra holds the better App Store score, 4.7 against 3.2. That said, the two scores are not equally well evidenced: Algebra has 1.3K ratings behind it against 109, so its average is the more settled of the two. Written reviews point the same way: 83% of Algebra's written reviews are positive against 42% of TT Pre's.

Algebra ships an update every 4 months, TT Pre every 2 months. The most recent releases landed on September 22, 2026 and September 21, 2026 respectively.
