Built an app to finally understand the calculator

Hey everyone,

a while back I posted here about CASify, the app I was building to help students actually understand how the TI-Nspire CAS works. A lot of you joined the waitlist or gave feedback, so I wanted to come back and share that it's finally live.

CASify is now available on the App Store, both as a free Lite version covering the basics, and a Pro version with the full range of topics through Analysis, Stochastics, and Geometry.

For anyone who doesn't know the backstory, I'm a high school student in Germany and built this because I kept watching classmates lose time in exams not because they didn't understand the math, but because they couldn't get the calculator to do what they needed fast enough. CASify walks through every function step by step instead, with real menu paths and examples.

It's availabe in German and English and iOS only, the Android versioin is still on my list. If you're on iOS and want to try it, here are both links or check out my website at casify.website

CASify Pro: https://apps.apple.com/de/app/id6776131288
CASify Lite: https://apps.apple.com/de/app/id6787475078

If anyone tries it, I'd genuinely love to hear what you think, good or bad. Building this alone next to school has been a lot of trial and error, so any feedback helps.

Thanks to everyone, I hope this reaches the right audience

Struggling to understand the calculator

Hey,

I'm a high school student in Germany, currently preparing for my final exams. During my studies I noticed that almost nobody in my class really knew how to properly use the TI-Nspire CAS even though it's required in almost every math course. YouTube videos exist but always lack practical context. Even some teachers struggle with certain functions.

Thats why Iam building CASify. An app for students that explains the TI-Nspire CAS step by step with tips and tricks.

I'm now looking for a few beta testers who want to try the app before the official launch. If you're a student who uses the TI-Nspire CAS and want early access, just join the waitlist at casify.website and I'll reach out once testing starts.

Unfortunately the app is currently in German only and available on iOS for now. Android and an English version are planned for later .

Would love to hear your thoughts.

Von der Abitur-Vorbereitung zur eigenen Lernapp

Hallo zusammen,

ich habe während meiner Vorbereitung auf das Mathe-Abitur gemerkt, wie komplex der Umgang mit dem Taschenrechner TI-Nspire CAS ist. Ich selber habe Mathe-LK und habe bei vielen Mitschülern mitbekommen, dass sie große Probleme beim Umgang mit dem CAS haben.

Neben dem Lernen fürs Abi habe ich dann also begonnen eine App für den CAS Taschenrechner zu entwickeln, um anderen Schülern zu helfen, den Umgang mit dem CAS zu lernen. Das Ziel ist es, Schülern den CAS so zu erklären, dass er kein Hindernis mehr darstellt, sondern ein Hilfswerkzeug wird.

Wenn ihr Fragen oder Interesse habt, schaut gerne auf meiner Website https://casify.website vorbei.

An die Lehrer hier: Welche Funktionen des TI-Nspire bereiten euren Schülern die größten Schwierigkeiten? Euer Feedback würde mir sehr helfen.

Vielen Dank im Voraus

Von der Abi-Vorbereitung zur eigenen App

Hallo zusammen,

ich habe während meiner Vorbereitung auf das Mathe-Abitur gemerkt, wie komplex der Umgang mit dem Taschenrechner TI-Nspire CAS ist. Ich selber habe Mathe-Lk und habe von manchen Bedienungen während dieser Zeit das erste Mal gelesen oder gehört.

Das Ziel ist es, Schülern den CAS so zu erklären, dass er kein Hindernis mehr darstellt, sondern ein Hilfswerkzeug wird.

Aktuell probiere ich mich über einen möglichen Markt zu informieren und herauszufinden, wie ich später meine App vermarkten kann. Ich denke das Problem mit Apps für Schüler ist deren begrenztes Budget. Habt ihr dort bereits Erfahrungsberichte sammeln können?

Zusätzlich zu der App habe ich eine Website programmiert. Dort ist auch eine Warteliste zu finden, damit ich einen Überblick behalten kann, wie hoch die Nachfrage ist. Meine Website findet ihr unter https://casify.website .

Ich freue mich über Feedback und Erfahrungsberichte.
