## What is Cardinal?

On your next adventure, make sure you take Cardinal — the perfect app companion for outdoors exploration.

Whether you’re setting out on a trip of a lifetime (like ascending Mount Everest), checking out green spaces in your area, or even just wandering around an unfamiliar city on a weekend break, Cardinal provides a wealth of information about your location and route. It’ll become an integral part of your adventures, helping you to really get to know new areas and navigate around them. Seeing this data update in real-time is incredibly fun and addictive too!

On its minimalistic and user-friendly interface, all of this data is at your fingertips:
— Compass (with True North & Magnetic North options)
— Altimeter (with Imperial & Metric options and use of GPS or barometer data for measurement)
— Coordinates (with formats including DMS, DD, & HDD)
— Barometer (with formats including kPa, mbar, psi, & mmHg)
— GPS signal strength indicator
— Map (with current position indicator)

By upgrading to Cardinal PRO, you’ll gain access to all customisation options as well as super-accurate location data. Plus, it’s only a one-time, low cost in-app purchase — not a subscription — that’ll give you lifetime access.

We hope you come to love using Cardinal as much we’ve enjoyed creating it. We’ve got plenty of ideas for making it even better in the pipeline, so keep an eye out for our app updates!
