We feel the same way you do - why another calculator? But we felt that we weren't satisfied with the other choices available. Existing apps either strive to make the iPhone look like a dollar store calculator, or they're too bulky and complex to be used for quick calculations. We found that we had to create something new and awesome: Better Calculator!

Better calculator is a multi-line, function driven calculator that starts up FAST and is simple to use, but also has the complex functions there when you need them.

Once you have it installed, Better Calculator will be the only calculator you'll ever use on your phone.



• OPTIMIZED FOR THE IPHONE 5!!! The unique vertical split screen that better calculator uses works best on the iPhone 5. It's one of the few calculators that will let you see the advanced functions and number keypad on the same screen.

• IT'S LIGHTWEIGHT AND STARTS UP FAST. This should be the only calculator you ever need to use!

• IT'S MULTI-LINE. You can see an entire formula on one line and scroll through it horizontally. And you can see the history of all of the formulas you've entered.

• PRESS A BUTTON TO COPY A RESULT. If you want to use a result of a previous formula in a new one, just press that line and it will get copied into the new one. Or use the handy "ANS" function which is always equal to the last good result.

• IT'S INTUITIVE. Just like on popular TI or Casio calculators, if you press "+", "-", "/", "%", etc. at the start of a line, the calculator knows you want to start with ANS. And the calculator will close a single parenthesis or function if you didn't. When you have a problem that needs solving we want you to be able to get an answer FAST instead of bugging you with error messages.

• IT'S POWERFULL. Tons of complex functions are available if you need them (trig, standard deviation, logs, etc.) but they stay hidden when you don't. Plus, using our special split-scroll interface you can view function buttons on the same screen as the number pad, helping you to enter your formulas faster.

• SEND YOURSELF AN E-MAIL. Are there any important results you need to remember? Press the e-mail button and all of your calculations are compiled into an easy to read e-mail that you can send right from the app.

• EVERYTHING YOU ENTER IS SAVED. Every formula you enter into Better Calc is automatically saved until you clear it. So even if the app shuts down, your work is there as soon as you restart it.

• WE LISTEN TO YOU. Better calc is definitely better, but we know it's not perfect. Do you think a button is in the wrong place or do you have a request for another function? Send us an e-mail!
