Speed Trig is the #1 app for memorizing the unit circle fast. Designed for students enrolled in Precalculus, the app quizzes you on the sine, cosine, tangent, and inverse trig values of the four main unit circle angles: π/2, π/3, π/4, and π/6. Our app was made by students, for students.
Beautiful Functions

Functions make sense when you can see them. Beautiful Functions turns every change in an equation into an immediate change on the graph. Move a slider, watch the curve respond, and understand what each parameter actually does - before memorizing a rule or solving an exercise. NOT JUST A GRAPHING CALCULATOR This is a visual learning environment designed to show how functions work. Watch a line cross a parabola twice, become tangent, then miss it completely. See a function reflect into its inverse. Switch the same parabola between Standard, Vertex, and Factored forms. Change amplitude, frequency, and phase, and watch every wave transform. EXPLORE WITH PURPOSE Use roots, intercepts, vertices, symmetry, extrema, inflection points, and asymptotes as visual guides instead of isolated definitions. Collapse the graph when you want to focus on an explanation, then bring it back to test your intuition. START FREE Start with Linear, Quadratic, Cubic, and Logarithmic Functions. Pro unlocks: • Linear + Quadratic • Exponential Functions • Trigonometric Functions • Function Transformations • Rational Functions • Absolute Value Functions • Inverse functions and slope relationships • Vertex and Factored form editing One-time purchase unlocks every Pro screen and feature. No subscription. Built for high school and university students, teachers, tutors, parents, and anyone who wants to understand functions instead of memorizing them. Download Beautiful Functions and see what equations mean.

Verdict
The clearest difference is in-app purchases: Speed Trigonometry at none against Beautiful Functions's 1. Beautiful Functions's advantage is update cadence (every 2 months vs every 14 months). On price, ads, device support and iOS requirement there is nothing between them.
