Cannot entre equations the Wright way

Is not letting me enter an inequality like this: 12/(x+1)>2(x+6). I want my money back!

Response from developer

We are very sorry to hear that the app does not work for you. On the App Store product page, we provide app description and screenshots which highlight the features and functionality of the app and inform our customers about limitations, if any. The current version of the app does not support inequalities with variables in the denominator and this limitation is clearly written in the app description. The online versions of our apps are available absolutely free on our website https://intemodino.com, so you can try them to understand if they are tailored to your needs. We are constantly adding new features. If you have any ideas and suggestions for future updates, please contact us at https://intemodino.com/en/contact-us.html

I want my 4.99 back

I can't use this calculator at all and I had to buy another one.

Horrible!!

I demand a refund! Included in the $7.99 purchase were supposed to be several types of calculators with different functions. ALL the calculators are the same and neither had basic functions such as radicals, exponents, negatives or fractions.

DO NOT GET

A waste of money!
Please do not purchase!

Could be a whole lot better

If you want basic solving then this is an ok app. If you have to solve something like y<2x+3 this app will not help and for a paid app this is not acceptable. If you say to yourself they'll fix it with an update, I have had this app for 5 months and they haven't updated or fixed squat. Spend your money somewhere else.
