Graph Equations
Instantly
A powerful graphing calculator with an intuitive, gesture-driven interface. Type naturally, visualize instantly. Pure mathematical exploration.
PlotCraft is a graphing calculator app for iPhone that lets you visualize mathematical equations instantly, priced at $0.99 as a one-time purchase with no subscriptions. It supports over 20 mathematical functions including trigonometric (sin, cos, tan, asin, acos, atan), algebraic (sqrt, abs, pow, floor, ceil, round), and logarithmic (log, ln, exp) functions, plus constants pi and e. You can plot unlimited equations simultaneously in eight distinct colors on an interactive canvas with pinch-to-zoom, pan navigation, and real-time coordinate display. The app includes 12 preset functions for quick exploration, three visual themes (Dark, Light, and Midnight), and smart equation input with implicit multiplication support. PlotCraft works entirely offline, collects zero user data, and requires no account. It is published by Applestan, an independent iOS development studio based in the Netherlands.
