# Trig Solver vs Math AI

The clearest difference is in-app purchases: Trig Solver at none against Math AI's 4. Trig Solver also leads on ads (none vs shown) and review sentiment (74% vs 64%). Math AI's advantage is update cadence (every 3 weeks vs every 28 months) and ratings volume (1.4K vs 78). On price, rating and device support there is nothing between them.

Both are free to download. Math AI sells 4 in-app purchases, starting at $0.99 per 7 days. Trig Solver asks for nothing beyond the download.

On the App Store both sit at effectively the same score — 4.3 for Trig Solver against 4.2 for Math AI. That said, the two scores are not equally well evidenced: Math AI has 1.4K ratings behind it against 78, so its average is the more settled of the two. Written reviews are what separate them: 74% of Trig Solver's written reviews are positive against 64% of Math AI's.

Trig Solver ships an update every 28 months, Math AI every 3 weeks. The most recent releases landed on October 15, 2026 and October 13, 2026 respectively.
