Know where the next water is, before your bottle runs out. droply maps springs, fountains, taps and refill stations, with notes from the people who filled up there yesterday. The app exists for longer, but we are just launching a new feature: The water planner along trails. Always see when the next water is upcoming on your hike, know where the dry stretches are and carry less weight through water afterall.
How do you plan how much water to carry on a hike? I was optimizing the weight of all my equipment: Tent, sleeping bag, backpack, everything ultralight. The only thing that didn't have a technological option to save weight: Water. I started with 6 liters in the desert of New Mexico when I started the Continental Divide Trail in 2024. Dropped half of it after a mile, because it was too heavy. So - would you use an app that tells you where the next water is, so you can carry accordingly?
