I was up in Boston last weekend when Phil texted me that he was going to go for a hike. With the AllTrails App, he sent me his route around Cliff Pond. I could log on at anytime and see exactly where he was, which you can see on the map. The app would also send me periodic texts of where he was or he could send me a text of where he was on the route.
What a great feature, called Lifeline, especially when hiking alone. Even if you never need it, it’s always safe and fun to see where someone is hiking!
Features like these are what makes technology (which I often find intrusive) great!
