PI 84 Graphing & Fraction Calc
Advanced Scientific Calculator
Free · Designed for iPad. Not verified for macOS.
The graphing calculator you wish you had in class.
Pi 84 is a free scientific graphing calculator built for high school and college students. It handles everything from everyday arithmetic to graphing functions to fraction calculations — with a clean, modern interface designed for touch screens, not 1990s hardware.
NO MORE $120 CALCULATORS
Why carry a bulky, expensive graphing calculator when your iPhone can do it better? Pi 84 gives you the power of a full scientific and graphing calculator — for free. Whether you're in Algebra I or Calculus II, Pi 84 has you covered.
GRAPHING MADE SIMPLE
Plot functions instantly with smooth, interactive 2D graphs. Pinch to zoom, drag to pan, and trace along curves with your finger. Graphing on a touch screen is how it was always meant to be — fast, visual, and intuitive.
- Plot multiple functions simultaneously
- Pinch-to-zoom and drag-to-pan
- Trace points along curves
- Find intersections and key points visually
FRACTIONS WITHOUT THE HEADACHE
Pi 84 handles fraction calculations natively. Add, subtract, multiply, and divide fractions with ease. Results display as both simplified fractions and decimals, so you can work in whichever format your assignment requires. No more converting by hand.
MEMORY DRAWER — YOUR VISUAL CLIPBOARD
Forget fumbling with M+, M-, and MR keys. Pi 84's Memory Drawer lets you save as many numbers as you want and access them anytime. Tap to store a result, and it appears in a visual drawer you can pull open whenever you need it. It's like having an unlimited clipboard for your calculations — something no other graphing calculator app offers.
FULL SCIENTIFIC CALCULATOR
Everything you need for math and science coursework:
- Trigonometric functions (sin, cos, tan and inverses)
- Logarithmic and exponential functions
- Powers, roots, and factorials

DESIGNED FOR STUDENTS
Pi 84 was built from the ground up with students in mind. The interface is clean and uncluttered, buttons are easy to tap, and everything is where you'd expect it to be. No manual needed — if you've used a scientific calculator before, you already know how to use Pi 84.
