## What is Class Calc Graphing Calculator?

Test-safe calculator. Statistics • Graphing • Scientific • Matrix calculator. 100% free. No ads. No “upgrade to unlock” functions. All equivalent functions of a TI 84 calculator, Casio calculator or HP calculator.

Paying $100+ for a graphing calculator 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. Not anymore!
4. 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.

*Note: Teacher only has access to whether the student is in lockdown mode or not, and nothing else. The teachers will NOT be able to control their student’s device.

To get started, or to help your teacher get started, contact us at team@classcalc.com, or visit our tutorials at classcalc.com/tutorials.

### 5/5 — Teacher

*2026-03-04, version 1.12.26*

Great too

### 1/5 — Absolutely terrible app

*2026-02-24, version 1.12.26*

During a self lock, ClasCalc removes the ability to turn off the phone.  I was not able to exit self lock by pressing the “self lock” button thus bricking my $1000 device into a $10 calculator.  This could be potentially dangerous in the case of an emergency and needs to be fixed immediately. 

This was done on an iPhone 17 Pro.

### 5/5 — Very good appp

*2026-02-09, version 1.12.26*

Help me a lot for the examm, Recommend for all of you guysss

### 5/5 — Class

*2026-01-27, version 1.12.26*

Our professor have us use this app for our class and it’s very convenient.

### 5/5 — The best

*2025-10-29, version 1.12.26*

My favorite calculator app ever. I don’t touch any other one

### 4/5 — Very good…

*2025-07-14, version 1.12.26*

This app is very good; that it is free is phenomenal. However, I wish there was a dark mode as I find the default colour a bit harsh. Kudos to the dev(s)for making this available to the community.

### 5/5 — Way better than classic calc on apple

*2025-02-23, version 1.12.26*

I love this and being able to form and actual equation and viewing my previous problems

### 5/5 — Great calculator

*2024-10-03, version 1.12.26*

At last one free, good looking and ergonomic option for a scientific calculator. Keep up the good work!

### 5/5 — Great app

*2024-08-26, version 1.12.26*

Absolutely the best calc I’ve had in a while. Only things I have against it is that the graph is a little glitchy and imaginary numbers aren’t supported

### 4/5 — Comprehensive calculator

*2024-07-24*

I generally find that a great app. 

I feel that my rating is a bit unfair, in that I’m also rating it on something that I’ve found difficult: entering expressions and formula, which has resulted in errors. That’s probably lack of understanding/user error
