Halo Calculator

The all-new calculator for mobile

Halo Calculator is the all-new calculator redesigned for mobile devices. It’s 100% free with no ads. Ever.

Redesigned for mobile:

• Smarter controls – tap, hold and swipe for common functions, such as calculating the result, starting a new equation or changing theme and layout. Smarter controls create a more natural and intuitive experience compared to old calculator apps

• Your choice of layout – choose between the new and unique ‘Halo’ layout or switch to the more familiar ‘Classic’ view. Just tap and hold any button to switch

• Easy-to-reach buttons – whether you use the Halo or Classic layout, all buttons are positioned in the middle of the screen. This means all controls are in easy-reach when using your phone one-handed

• Tap to copy equation – Tapping on the result or equation takes a copy of your calculation so you can easily paste it into other apps (like messaging and email). This makes sharing calculations with others quick and easy

A fresh look:

• Halo Calculator is modern and minimalistic. Vibrant colours matched with translucent whites and thin fonts create a fresh and light feel

• Personalise your experience with 7 different themes. Just swipe right

Easy to use:

• Introducing an easier way calculate percentages with ‘% of’. Percentages are shown in plain English and are easier to calculate and read. So ‘9% x 360’ on an old calculator app is now ‘9% of 360’ in Halo Calculator

• Everything you need is just a swipe or tap away, with no complicated menus and settings

• If you ever forget how to use Halo Calculator simply tap the icon in the bottom right hand corner to see the ‘Tips’ screen for a quick reminder of the controls
