In VATCalc you are presented with 4 fields:
Net Value, VAT Value, Total Value & % VAT. Add your VAT percentage, and then type either your net value or total value. The app will calculate the opposite value and the VAT value. It's a no-brainer!
You can easily copy a value (except for the VAT percentage) by taping on the field name, and paste it anywhere you want.
To make things even better, the VAT percentage is stored between your calculating sessions, so you will find it there when you reopen the app!
The app features non-intrussive ads on the bottom.
Full Network Access/View Network Connections/View Wi-Fi Connections: App is cheking if you have any data transfer active to deliver you a non-intrussive ad.
Location Access (GPS or Network based): Used by the non-intrussive ads to provide offers nearby you, if available.
Note: This app is optimized to look great on phones. It works on tablets as well, but there will be a lot of empty areas. This does not affect the functionality, only the looks of it.
