I am actively developing this app and have many new features planned for updates in the next few months. But would welcome feature requests so that I make sure the app only does what you want it to do and not bloated with features that get in your way! Let me know what would be most helpful.

*IMPORTANT* This app will automatically display the correct currency symbol for the International Settings of your device. Screen shots below were taken on a UK device hence GBP. Your device will display your local currency.

If you are looking for pretty graphics or a video game experience then this is NOT the App for you! But if you need to do financial calculations quickly then the elegant Profit and Markup Calculator will be indispensable on your iPhone or iPad.
