👆 Use the arrow keys or your fingers to navigate — same layout you already know.
📚 Covers everything you need: Pre-Algebra, Algebra 1 & 2, Pre-Calculus, Calculus, Statistics, SAT & ACT prep.

🚀 BETTER THAN A HANDHELD
• Taculator 84 is 100X faster than a physical graphing calculator because it uses the full calculation power of your phone, while handheld calculators like the TI 84 or Casio are often slow.
• High-resolution graphing window: make sharper, more beautiful graphs.
• Your new 84 calculator weighs nothing and is always in your pocket.
• Share your calculations with friends as a text message or email.
• No more dead batteries, no more replacing a lost TI84.

🧮 Math Functions
• Scientific calculator with all basic arithmetic and advanced functions.
• Ability to scroll through history and copy previous calculations.
• Complex numbers support.
• Probability functions: nPr, nCr, factorial, random numbers.
• Enter fractions easily.
• Convert angles and use DMS format.

📈 Graphing Functions
• Graph every function you want and trace for X- and Y-values.
• Calculate intersection, zero, minimum, maximum, integral, and derivative.
• Pinch to zoom and adjust the window settings.
• Statistical plots: histogram, box plot, scatter plot, xy-line plot.
• Draw vertical, horizontal, tangent, and circle.

🔢 Matrix Calculator
• Store matrices and reuse them using shortcuts like [A], [B], [C],...
• Matrix arithmetic: scalar multiplication, addition & subtraction, multiplication, power of a matrix.
• Calculate transpose, determinant, dimension, inverse matrix, row echelon form, reduced row echelon form, identity matrix, cumulated sum.

📊 List, Statistics, and Distribution
• Use the stat list editor to enter your list values.
• Perform 1- and 2-Variable statistics.
• Use lists to calculate84 min, max, mean, median, sum, product, standard deviation, variance.
• Find best-fit regressions: LinReg (ax+b), LinReg (a+bx), QuadReg, CubicReg, QuartReg, LnReg, ExpReg, PwrReg, Logistic, SinReg.
• Perform statistical tests: Z-Test, T-Test, 2-SampleZTest, 2-SampleTTest, Ti84, 1-PropZTest, 2-PropZTest, ZInterval, TInterval, 2-SampleZInterval, 2-SampleTInterval, 1PropZInterval.
• Calculate various distributions: Normalpdf/cdf, invT, Tpdf/cdf, χ²pdf/cdf, Fpdf/cdf, Poissonpdf/cdf, Binompdf/cdf, Geometpdf/cdf.

💡 Command Catalog & Syntax Help
• Built-in Catalog & Help section with all the commands you need.

Comments on Taculator 84 Graphing Calc for Android

★★★★☆ Sander Lesage · May 26, 2022

I like it! Vibrate on key press would be a nice addition. I also have some small issues where selecting a previous result shows an empty pop menu when in dark mode (switching dark mode also shows the let's get started menu again). The up arrow also does not select the previous result.

★★★★★ Mary Thompson · Sep 12, 2021

This is exactly what I needed. It does the job for my Trigonometry and Precalculus courses as a good Ti 84 alternative.

★★★★★ nia · Nov 5, 2021

I just needed a quick replacement for my TI-84 Plus CE-T calculator, so I didn't buy it. But it seems really good to me

★☆☆☆☆ Ky Jackson · Jan 26, 2022

I get that the app needs to make money, but after I hit y= and typed in my equation, I tried to find x (hit shift, trace, 5). I was surprised to find out that to find x I needed to buy tabulator pro, rendering the app completely useless for me personally. Everything else I needed to do worked almost completely fine though.

★★☆☆☆ Eric Kohler · Sep 11, 2021

Graphing doesn't work. I entered 3 equations, hit the graph button, and after a 3-second delay, a blank graph appears. I tried very simple equations (y = 2x, y = -x, etc.), made sure the minimum and maximum axis values were appropriate (-10 to 10 on both axes), and it won't plot the graphs. I'll try a different app.

★☆☆☆☆ Jessi Ellis · Jun 4, 2022

I'm pretty frustrated that the functions you can easily get for free on your standard phone calculator are the only free functions on here. You're better off spending your money on an actual graphing or stats calculator
