Totalizer, my second watch app, is decidedly less ambitious than the first one - but regardless, it is something I felt I had to make. After trying five different calculator apps, and finding annoying flaws in all of them, I decided to make a 'perfect' calculator app for the watch. Not the most feature loaded one, but one that can actually be used frustration-free, when needed. Here's what the app has: • Big, easy to hit buttons, while keeping everything you need on a single screen: Note that I've made the operator buttons narrower, so that the numeric buttons could be as large as possible - because the right screen side edge is really easy to hit correctly. • Perfect button responsiveness, as the app is native. • Quick launch - probably the quickest possible, actually. • Running total will update as you type, no need for the "=" button. • 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% = 90I have no idea why so many calculator apps get this feature wrong. • One tap to add parentheses around the equation - just tap the running total number. Smart delete for parentheses - if you delete the right one, the left one gets deleted too. • The app has the secondary layout where the buttons are even bigger, and the operators can be reached with a button press, a screen swipe, or a crown rotation: • Complications for all the watch faces are available, for the quick app launch, and to display the last result. If all of the above sounds like "well, how else it should be working?" to you, then I've achieved what I've set to do. However, it took a lot of thinking, designing, adding, and subtracting (sorry, I just couldn't resist) to get there, which I think comes through when you start using it. The app is $0.99. It may seem simple, but it's really not something just thrown together, and I really believe it's better than what's out there, where it really matters.

I'll read and consider everything.
