### 1/5 — Cannot entre equations the Wright way

*2018-01-09*

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

### 1/5 — I want my 4.99 back

*2017-03-22*

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

### 1/5 — Horrible!!

*2016-11-08*

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.

### 1/5 — DO NOT GET

*2016-09-29*

A waste of money!
Please do not purchase!

### 2/5 — Could be a whole lot better

*2016-06-26*

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.

### 1/5 — Horrible

*2016-04-11*

Waste of $3.00. It doesn't even let you write the whole equation. Would not recommend.
