The goal for the Totalizer was to make a watch calculator that you'll always enjoy using. It has:
+ Big, easy to hit buttons, while keeping everything you need on a single screen.
+ Running total will update as you type, no need for the "=" button.
+ Perfect button responsiveness.
+ Instant launch time.
+ Full equation preview as you type. Equation preview is in the title bar, freeing space for bigger buttons.
+ Easily accessible "%" button, which I think is the most used feature for an app of this kind (to calculate a tip, a sale, or a price after tax).
+ Percent works as you'd expect it to:
200+10% = 220
100-10% = 90
+ Has the secondary layout where the buttons are as big as possible, and the operators can be reached with a button press or a screen swipe.
+ One tap to add parentheses around the equation - just tap the running total number.
+ Complications are available for the quick app launch, and to display the last result.

The above may sound obvious, but it took a lot of thinking, designing, adding, and subtracting to get there, which comes through when you start using it.

If you have an idea how to make it even better - I'm listening!
