Margin now has a Markup side. Tap MARKUP to price from cost, so 300% on a $40 cost gives $160. Flip back and forth and your numbers carry across. If a margin can't work, the app now tells you why instead of leaving Sell empty.

Dark mode. The app now follows your device's appearance, and Settings has a switch if you want to keep it light or dark. Calculations keep their full precision between steps, so a cost with a discount applied gives the exact gross margin. In Convert, tapping the other row no longer nudges the value you did not touch.

Zero now sits under the 2 on the keypad, with the decimal point next to it, so both land where your thumb expects.

Convert works in both directions now. Tap either row to enter an amount and the other side follows. The keypad does arithmetic in Convert too, so you can add or multiply before you convert. Two fixes: pasting a value into a calculation already in progress now adds to it instead of replacing it, and the second currency can be changed by tapping it.
