### 1/5 — Very slow

*2026-05-07*

There is a significant delay between the key taps and the actual numbers showing up in the calculator display. Unless it is fixed, the app is unusable.

### 1/5 — i don’t usually leave reviews but…

*2026-03-06*

Honestly, just buy the physical calculator it’s cheaper, it’s а shame we have to pay а subscription at an extortionate price for а product that doesn’t require any server hosting or anything

### 5/5 — Brilliant for online tuition

*2026-02-25*

Brilliant for online tuition and cheaper per year for license compared to Casio’s calculator emulations for pc!

### 1/5 — No me deja ingresar mi licencia

*2025-09-01*

Yo tengo una licencia y no puedo utilizar las herramientas de la aplicación por que no me da la opción de ingresar licencia, cuando toco alguna función solo dice “adquiera una licencia” la cuál ya tengo pero desde la interfaz no permite iniciar sesión.

### 2/5 — Won’t work without internet connection

*2025-07-07*

As a set of calculators it seems fine BUT if you don’t have an active internet connection you can’t use it. (Unless you had it open and had chosen a calculator when you did)
But if in a plane, ferry or any number of places where you might not reception it won’t work.
Why on earth it needs to have an active connection is beyond me. I shall not take it past the trial period for that reason alone. There are plenty of calculators that don’t need an internet connection to start up.

### 1/5 — QR software not working

*2025-03-26*

Upon purchasing this calculator, you are given a feature to scan a qr code on the display, and have this app decode it for you, so you can view it on your device. It seems that this has stopped working.

This is the only feature of this app that isn’t hidden behind a paywall, even for those who have purchased the calculator, and it’s broken.

### 1/5 — Why does this have to exist as a yearly paid service?

*2025-02-01*

Ngl, I don’t even know if the app’s features are good, because EVERYTHING is locked behind a damn yearly £14.99 “license”. I’m not gonna pay £44.97 during the time it takes to get my maths degree, when I could just buy a calculator, OR use my phone’s damn built in calculator. Fellas, please stay away from this app.

### 1/5 — Terrible App

*2024-11-10*

I’ve bought a calculator and I’ve got the license code from your website. Why there is no opinion for us to input the license code in the app, instead requiring us to pay extra money to allow us to use your app? It’s nonsense.

### 2/5 — Should be free if you buy one of these calculators

*2024-08-11*

Why are they charging for this ? If you’ve invested a fair bit of money in one of these Classwiz calculators then there should be a free code in the box to get this app free.

### 1/5 — App crashes

*2024-01-31*

I just got a 991 EX plus ClassWiz calculator. Thing works great. I’ve had a 115 ES plus before so it’s a bit of an upgrade. When I learned about the QR code feature, I immediately wanted to try it. However, when I tried it with this app, it doesn’t work. App just keeps crashing. Over and over. As soon as you click on the QR code button. I hope they fix it soon. I will change my rating if they do.
