Totalizer vs Mathintosh

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. + 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! Privacy Policy: Totalizer does not collect or transmit any kind of data whatsoever.
