### 1/5 — Out of run,don’t buy it

*2021-10-25, version 1.5.7*

Out of run,don’t buy it !

### 1/5 — Garbage

*2020-10-12, version 1.5.7*

Absolute waste of money it was a complete scam

### 2/5 — Not worth the money

*2020-10-11, version 1.5.7*

I bought this hoping to be able to use it to solve for some linear regression problems I had in my class, but this app is basically just a tutorial for using an actual Ti-84 with some math questions in it, unless you want to spend $10 (or in my case $15 because I had to buy this app to use it) you won’t get to use an actual Ti-84 calculator on your phone

### 1/5 — DO NOT BUY

*2020-02-02, version 1.5.7*

Extremely misleading and the creators know this. I was sitting in class trying to download a calculator for my college course. 5 dollars for information that I can easily google or look in my class notes for. DO NOT WASTE YOUR MONEY. SHAME ON THE CREATORS.

### 1/5 — Wouldn’t recommend this to anyone!

*2019-05-07, version 1.5.7*

This is by far the worst paid app I’ve come across! You can’t even press anything when you want to graph functions! It’s just pictures of how to enter them instead of actual help!

### 4/5 — It is good but

*2019-04-20, version 1.5.7*

Need a ZOOM ability... som of the stuff is too small to see well could have used pinch to zoom.

### 1/5 — Lies

*2019-04-13, version 1.5.7*

I thought this was a calc. It’s not. I feel played....

### 5/5 — WARNING: this app is a manual

*2019-01-25, version 1.5.7*

This is a great calculator manual. 👍👍👍

### 1/5 — DO NOT BUY IF YOU ARE LOOKING FOR A CALCULATOR

*2019-01-10, version 1.5.7*

This app is not a calculator. It is a manual for a calculator. DONT FALL FOR THE TRICK

### 1/5 — I WANT MY MONEY BACK!

*2018-11-05*

I’ve written a nice email regarding your app costing $17 CAD, and doing absolutely nothing for helping in terms of your “APPS” button doesn’t function the same as the TI 84 calculator and your financial calculator seems to have some sort of bug to. Please refund my money! This is bull!
