Calculator • Unit Converter • Tip Calculator • RPN Mode • Full Scientific • History Tape All the power you need, wrapped in a beautifully designed interface that's simple without being simplistic. ADAPTS TO YOU Do you like big buttons, or small? Like minimalist interfaces, or are you a fan of bright and flashy? Prefer small fonts to see more detail, or big text and easy to read buttons? Codex Calc adapts itself to the way *you* like to work. FEATURES Everything you'd expect, plus: • History tape records all entries and calculations • Full suite of standard and scientific calculator functions • Unit conversion mode for forward and reverse conversions • Full tip calculator mode - taxes, tip, per-person amounts • RPN mode fully integrated • Rotation lock and sound on/off toggles • Seven different professionally designed visual themes • Multi-number memory and full set of memory-store operators • Full control over history tape font size • Single and multiple-line history tape formats • Large and small button sizes • Settings for customization (number formatting, behavior of clear key, display of calculation details, much more) Calculations: • Trig functions in degrees and radians • Log and power/exponentials • Scientific notation / exponent mode • Rounding and truncating • Random number generation • Parenthesis and sub-expressions ...and more! INTUITIVE TOUCH INTERFACE Take full advantage of your device's capabilities: • Overlays - rather than making buttons smaller to fit more, Codex Calc uses intuitive overlays on the existing buttons. • Popup Menus - hidden until you need them, pop-up context menus give you more power when the default action isn't quite what you need. • Zoomable History Tape - Tap the history tape to expand for more detail, change the font size, copy contents to clipboard, or forward as an email. View as single-lines to save space, or use multi-line view for more detail. • Multiple Flexible Layouts - Portrait and landscape, large and small buttons, and seven different graphical themes. • Easy-Touch Everything - Codex Calc's entire design approach revolves around "touch to activate." Tap the tape to see it bigger, swipe to scroll, long-press a button for more options, tap the display to copy or paste, etc.

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.
