I've copy pasted the description from the TestFlight app description here:
Thank you for beta testing Headings! You can track your hikes, drop pins, view all of your past hikes and pins with a free Headings account
Tips for beta testing: * Test the app during a hike, bike ride, or your commute to work by pressing the “Start Hike” button. When you’ve reached your destination, tap on the red flag to stop recording * Look at the stats, are they accurate? * How was your battery life? Did it drain too much too quickly? * Save them to your account, did signing up for a new account work? * Drop pins along the way and see if they show up in the map * Log out of your account and log back in. Did all of your previously saved info come back?
Hope this helps!
