# Trigonometry Quick Reference vs Calculus

The clearest difference is device support: Calculus at 3 against Trigonometry Quick Reference's 1. Trigonometry Quick Reference's advantage is price ($0.99 vs $1.99) and iOS requirement (12.0 vs 15.6). On ads and in-app purchases there is nothing between them.

Trigonometry Quick Reference costs $0.99 and Calculus $1.99 up front. Neither carries in-app purchases, so what you see is what you pay.
