FIVE REASONS WHY YOU NEED THIS APP 1. Keyboard and command syntax similar to physical graphing calculators -> No need to learn a new calculator. 2. Powerful emulator -> No more waiting to graph functions compared to slow physical handhelds. 3. Enter fractions, equations or functions in the same way as you would write them on paper. 4. Never forget your calculator at home! It's always ready on your iPhone & iPad, and it weighs nothing. 5. Save more than 80% compared to the retail price of an actual calculator which is over $100. FULL GRAPHING CALCULATOR • Graph more than ten functions at once, each with a different color • Add Lines, Horizontals, Verticals, and Tangents to the graph • Use your finger or the arrow keys to trace the coordinates of your functions • Calculate the Zero, Minimum, Maximum, Intersection, and Derivative • Find integrals and color the area under the function • Set the X and Y coordinates of the graphing window; zoom in and out with your fingers ADVANCED SCIENTIFIC CALCULATOR • Enter calculations in natural textbook format • Includes all basic arithmetic (+, -, x, ÷, ^, ², √, π, …) • Use advanced functions like sin, cos, tan, e, ln, Σ, ... • Scroll your calculation history and modify existing calculations with one tab • Store and recall variables • Quadratic Equation Solver • Statistics and List menu will be added in an update soon MATRIX CALCULATOR • Work with matrices the easy way -> store them or enter them directly on the calculator interface • Do basic matrix arithmetic operations like addition, subtraction, multiplication or power of a Matrix • Put the matrix into Reduced Row-Echelon Form and solve linear equation systems • Calculate the determinant, inversion or transpose the matrix TUTORIAL AND CATALOG • Easy to understand tutorial to get started • Full Catalog of all commands with syntax, example, and possible error messages • Tab on highlighted math terms to read on point definitions PERFECT FOR HIGH SCHOOL & COLLEGE STUDENTS • Recommended by teachers to use in math classes • Pre-Algebra, Algebra 1 & 2 • Pre-Calculus, Calculus • Permitted on SAT/ ACT/ AP (your phone might not be permitted, but you can use the app for homework and borrow an actual calculator from your school for the test)

#### Stat

1By Hi friends 41702The stat function still doesn’t work. Horrible app, go somewhere else for a graphing calculator app.#### Sadly

1By burbuja50##Definitely needs improve thus app. Not enough for somebody who start to use it. Incomplete app#### Total Garbage

1By whatadisappointgappThis calculator is no where close to the TI84, can’t even calculate std deviation for a simple data list. False advertising... I want a refund!#### Don’t buy this

1By Nathan EastwoodI just got this app thinking to myself “Oh perfect! A TI-84 calculator app that is relatively cheap! Awesome!” No. It’s not. When I went to go on to stat, it said it was still in development. I just payed $5 for something incomplete. Don’t buy the pile of garbage. It’s not worth it.#### No reset button

3By smokeybeckThe calculator is very good, but unlike the actual machine. There is no reset button. Adding one of those would really make it much easier when the calculator breaks.#### The list bottom don’t work

1By ethan755775I literally just bought the app so I could plot my points for homework and it doesn’t work#### Unfinished trash heap

1By DiamondfroggamingCurrently in Algebra II, needed this on short notice. Open it, right away, “STAT” is under development. IF YOU'RE GOING TO CHARGE $5 FOR THIS, MAKE IT FUNCTIONAL FIRST.#### Crap

1By frickle frackle tickle tacklePaid for an app that doesn’t even work fully. When you hit stat it says wait until the next update and it’ll work, so I waited. I updated the app and it said the exact same thing, wait until the next update. The class I’m using this for uses stat quite often, vv inconvenient.#### Garbage

1By Worst Calculator EverNo tables until future updates and I paid for this!!!! Bad bad bad#### It’s ok
