CASify: TI-Nspire CAS Tutor
Learn your graphing calculator
$0.99 · Designed for iPad. Not verified for macOS.
CASify explains your CAS calculator the way you really need it in your exams. Every function, every key, every menu path, step by step.
We believe that a CAS calculator shouldn't be an obstacle. It's the tool you use to write your exams and, in the end, your finals. It takes work off your hands. It solves equations, it differentiates, it integrates. But only if you know where to find it and what to type.
That's why you won't get a manual here, but guides for the material you'll actually come across. From the basics through algebra and systems of equations to calculus, geometry, vectors and probability, sorted by grade from 7th grade all the way to your finals. All offline, no account, no ads, pay once and you're done.
CASify is a learning app that explains your CAS calculator to you calmly and at your own pace. The app is made especially for high school students and includes guides for calculus, algebra, probability, geometry and the basic operation of the calculator.
What you'll find in the app:
Clear guides for every important function and key, in the right order
Long menu paths laid out clearly with CASify, so a confusing route turns into a sequence you can follow
Formulas in real CAS notation
A favorites feature that lets you mark the most important functions
From 7th grade to your finals, CASify is sorted by grade, so the app stays clear and easy to understand for everyone
Search helps you find relevant content quickly
Content-wise, CASify covers what you really come across in high school. From the basics through algebra and solving systems of equations to calculus, geometry, vectors and probability. Every function is explained with fitting examples as well as small tips and tricks, so you don't just know how something works, but also why it works that way.
That's what makes CASify valuable when it really matters, whether you're preparing for your next exam or for your finals. Instead of clicking through endless menus, your head is free for what actually counts.
What CASify won't put in your way:
The app works completely offline, whether you're studying at home or on the go
You don't need an account or registration and can get started right after installing
There are no ads and your usage isn't tracked
No data is collected about you
You only pay once and then have full, permanent access to everything, with no hidden costs
CASify is available in German and English. You can also choose between a light and a dark theme and use the app on both iPhone and iPad.
In the end, it's about a pretty simple idea. Nobody should fail because of how to operate the calculator when they understood the math long ago. You should be able to focus on the problem and not on searching for the right key. The app explains which key that is and why it does the right thing.
Ratings & Reviews
- This app hasn’t received enough ratings or reviews to display an overview.
Your calculator is only useful if you know how to use it. That applies to your CAS just as much as to CASify. That's why, in this version, CASify explains itself for the first time.
New tutorial: You choose what you want explained. How the home screen is laid out, what's inside a chapter, why input and results look the way they do on the display. If you want everything in order, start with the basics. If you only want to look up one thing, jump straight to it. You can find the tutorial anytime in Settings.
Set up in a few steps: When you first open the app, you choose your language, grade and appearance. That way you can tailor CASify to you right from the start. Later on, you can fine-tune everything in Settings.
We've also made improvements in many places. Navigation runs more smoothly, the layout looks cleaner, and the texts in the app are clearer.
