NEW DESIGN • The answer comes first: one large figure, the GST beneath it, and a simple "ex + GST = inc" line so you can see it adds up • Price boxes are outlined in your accent colour, and if a keystroke is refused (such as a third decimal place) the box tells you why • The GST Calc logo sits at the top of every screen • New Appearance settings with Light, Dark and Auto previews and larger accent colour swatches • Your recent GST calculations appear under the calculator on iPhone and Mac; tap one to bring it back BRIGHTER COLOURS • All five accent colours are brighter and richer: a cleaner blue, a vivid pink, purple, a new lime green and a true orange • Buttons and badges are filled with your colour, with text chosen so it stays easy to read • If you'd picked Rose, Emerald or Amber before, you'll now have Pink, Lime or Orange HISTORY AS RECEIPTS • Every saved calculation now looks like a till receipt, with each figure on its own line and the total at the bottom • Tap any line to copy that figure again • Reopen any calculation in the Calculator or Margin with one tap, exactly as you entered it • History ends with a running total of the ex GST, GST and inc GST amounts, handy when you're adding up a batch • On iPad and iPhone Duo, the History tab shows one long till roll beside a full receipt for the calculation you select MADE FOR IPAD • In portrait, the calculator runs across the top with your History below it; in landscape, History sits alongside • Bigger figures, and an on-screen number pad beside the price box • Settings shows Help right alongside, so you don't have to open it separately • The region menu is always on screen IPHONE DUO • Open it up and the calculator sits beside your History, filtered to the tool you're using • Half-folded like a book, the calculator and History each get their own side of the fold • Held upright, the calculator sits above the fold and History below it • Propped on a counter, the answer shows in large type on the upright half, with the price box on the half lying flat: handy for quoting customers MARGIN • A sell price that includes GST is now kept exactly as entered (for example, $20.07 no longer shows as $20.08) MAC • The same new design in the menu bar calculator and the app window • Reopen any calculation from History straight into the Calculator or Margin • A clearer header in light mode, and History fades softly at the edges instead of being cut off Thanks for using Aussie GST Calculator.
