Test-safe Statistics, Graphing, Scientific and Matrix Calculator. 100% Free. No Ads. No “upgrade To Unlock” Functions. All Equivalent Functions Of A Ti 84 Calculator, X84, Casio Calculator Or Hp Calculator.

Paying $100+ For A Ti 84 / Ti Nspire Graphing Calculator (Or Casio, Or Even Hp) Is Just Silly. Here’s Our Logic:

1. We’ve Built A Beautiful, Easy To Use Online Digital Calculator Right There On Your Phone.

2. The Problem Is, That You Can’t Use Your Phone On Tests, So You’re Stuck Paying $100+ For Your Calculator.

3. With Our Easy-to-use Test-mode Lockdown, You Can Now Use Classcalc On Tests. Teachers Can Ask Students To Temporarily Lock Their Own Devices* Out Of All Outside Distractions Such As Instagram, Calls And Texts, Keeping Students Focused In Class, And Preventing Cheating On Tests. Students Can Leave Test Mode Whenever, And Once They Do, The Teacher Is Notified.

Why do we need accessibility permissions when you're joining test mode?

In order to give teachers full trust that the students can't access data from other apps while on test mode, we make use of the accessibility services to make sure the student is using ClassCalc and only ClassCalc. Your data is 100% safe. We don't collect any data displayed on the screen. We analyze the behavior locally and only ask the teacher to make sure everything is fine on the student's end - no data is sent over.

I am a math professor at a community college and I have been using ClassCalc with my College Algebra, Statistics, and Calculus I students for a semester now and I don't think I will be going back to TI. This calculator has all or almost all of the features I need to teach my classes and they keep adding new features. The team is also very responsive to any needs I have. The user interface is also much easier to understand compared to TI graphing calculators and the cost savings is immense. So for today's modern students who have their phones within arms reach at all times this app seems to be a perfect replacement for traditional graphing calculators. Add in the test lock out feature and the web app and it has everything I need in the classroom.

The sleek design of this easy to use calculator is great for students and professionals alike! It has big buttons, easy to find functions, and is easy for plotting graphs. Best yet it offers standard deviations, allows for calculus functionalities, and as the cherry on the cake offers big help for linear algebra (matrices and other functions). I highly recommend this excellent user experience powerful calculator.

This is the best graphing calculator ever! I'm so sick of using TI graphing calculators and their slow, outdated user interface. Thankfully, my professor allowed us to use any calculator of our choice during quarantine. Finishing assignments have never been easier. Class calc has big colorful buttons that are self-explanatory and very easy to use. Never again will I have create custom lists and go through hundreds of menus just to graph a simple function. Everything is just a simple click away.
