### 5/5 — Well thought out application

*2025-06-10*

I am an avid numbers user on MAC but when it comes to iPhone I was always looking for similar options in a more compatible, easier to use function on a smaller screen. This application provides simple addition, subtraction, multiplication, division and percentage charts.  There is an option to export as PDF. There is a gallery view and list view on main menu to select the list to work on, app icon choices. You can add comments to data rows or swipe in other direction and delete that row. Edit option to drag and move around data, add spaces. Well thought out, of course not as powerful as numbers but this is a great list tool where you need mathematical assistance with a simple interface that is workable on iPhone screens. 
Besides the above this application really shines in being able to create invoices with your data. When exporting, there are multiple options to create a customizable pdf to simulate a professional invoice with company logo and option to design and label exactly like you like. 
Would love to see simple graph possibilities as well.

### 5/5 — Super useful
