*2017-03-27, version 3.8*

This application is excellent and it's price is reasonable.

### 5/5 — Excellent Calculator App.

*2016-02-06, version 3.8*

This is a great, 'free' (for the basic version) App.

It is super-easy to install, update, and, above all, use.

It is clear and logical, with various, distinct 'panels' which work together in the case of more advanced uses. For example, one panel will show a clear, large depiction of an everyday, 'classic' scientific calculator body (the graphics and layout of this 'calculator' make for a very convincing, realistic depiction of the real, everyday item). Another panel may show the outcome (if requested, and depending on the type of mathematical operation) in the form of a graph; again, very clear and intuitive, and drawn on a background of clear, easy to follow graph 'paper'. The other panels serve other such relevant, helpful uses.

To sum up, this App stretches from being a clear, easy to use, all-round calculator, to an App with the potential to go far further, producing graphs, charts, equations written in precise mathematical notation, and much more besides. A great App.

### 4/5 — Mr

*2015-12-05, version 3.8*

It is better to keeping multiple graphs on the screen & adding a button to clear the drawing.

### 5/5 — good

*2014-12-08, version 3.8*

This app very easy to use, this is one of the best apps that i have used.  Ipad mini
