Crumbs

Crumbs allows you to share details about your adventures with trusted contacts. Using check-in times, your contacts will also be notified if you do not return on time.
Crumbs is based around one simple rule for the outdoors: always tell someone where you're going.

For use with outdoor adventures, hiking, camping, or general travel. Use Crumbs to improve your safety and give your friends peace of mind that you arrived at your destination safely using e-mail notifications (text message support coming soon!).
