# Trigonometric Equations vs Linear Algebra Pro

The clearest difference is update cadence: Linear Algebra Pro at every 4 months against Trigonometric Equations's every 20 months. Trigonometric Equations's advantage is price ($0.99 vs $4.99) and iOS requirement (9.0 vs 16.0). On ads, in-app purchases and device support there is nothing between them.

Trigonometric Equations costs $0.99 and Linear Algebra Pro $4.99 up front. Neither carries in-app purchases, so what you see is what you pay.

Trigonometric Equations ships an update every 20 months, Linear Algebra Pro every 4 months. The most recent releases landed on September 21, 2026 and September 22, 2026 respectively.
