About Prime Calc—a better calculator
A calculator you can talk to. A widget you can use without unlocking your phone. An innovative fraction calculator. Introducing Prime Calc 3.0.
CALCULATOR
-Speak to calculate: just say what you want to calculate out loud and Prime Calc will calculate it. No need to press a button.
-Tap to undo: make a mistake? Just tap the calculator view field and undo your button presses one by one.
-Automatic decimal-to-fraction conversion: if you get a decimal result like "0.0588235294," Prime Calc will helpfully tell you that's 1/17.
-Fully viewable history: see what you just calculated or copy it to your clipboard.
TODAY WIDGET
-Just add Prime Calc's widget to your Notification Center and you can calculate anywhere—even on your lock screen.
FRACTION CALCULATOR
-Add, multiply, subtract, and divide fractions faster than ever. Redesigned in the latest version of Prime Calc.
TIP CALCULATOR
-Calculate tips. Split bills among friends. Easy.
FACTORS & COMPARE
-Find all of the factors of any number into the quadrillions using built-in algorithms, and see whether it's prime or not.
-Generate a random number.
-Compare two numbers to see their factors side by side, or find their LCD or GCF (great if you're in math class).
INTUITIVE MULTITASKING
-On iPad Air or newer, Prime Calc works with Split View and Slide Over multitasking, letting you calculate in more places than ever before.
3D TOUCH
-Launch straight into the main calculator, tip calculator, or factors/prime screen with 3D Touch shortcuts from the home screen icon.
FREE & AD-FREE
Prime Calc is free and has no ads. Really. And it takes up significantly less storage space than other calculator apps made for iOS. So what are you waiting for?
Supported Devices: iPhone 5s and newer, iPad Air and newer (iOS 9+).
Language: English only so far.
