Is there an app? There isn't a mobile app yet. You can still add RunwayHorse to your homescreen by following these instructions for iPhone or these for Android.
Can I plan multiple trips at once? Yes, you can plan as many trips at one time as you want. They're all available for you to see even after you're done with them.
How does sharing work?In your trip home, copy the shareable link that fellow travelers can use without a RunwayHorse account. They'll be able to view, but not edit, everything on the trip.
Is it safe to put my reservation numbers in?No one else, including us, can access your account. Everything you put into RunwayHorse is only for your eyes.
