TACULATOR 84 — GRAPHING CALCULATOR
Designed for use with TI-84, TI84 Plus and TI-83.

🎓 Your graphing calculator 84 for high school and college students.
✨ Includes all the commands and functions for advanced math, lists, statistics, distributions, stat plots, and more.
👆 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.
• Switch between full-screen graphs and normal mode.
• Zoom in and out with your fingers and adjust the window settings.
• Graph statistical plots like 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.
• It provides you with syntax help, examples, and possible error messages.
• Enter a command and the app will show you the right syntax next to the cursor.

🎯 PERFECT FOR
• Students who want a graphing calculator to use alongside TI 84 on their phone.
• Anyone preparing for SAT, ACT, AP Calculus or AP Statistics.
• Users coming from a TI84 Plus, TI 83 Plus or TI-84 Plus CE.
• Engineers, teachers and math enthusiasts.

Ratings and reviews

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.

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

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 taculator pro, rendering the app completely useless for me personally. Everything else I needed to do worked almost completely fine though.

What’s new

Change between 2ND and SHIFT mode and personalize your calculator's keyboard.
