With 12 million downloads, AllTrails is one of the most popular apps out there for planning your next hike. It boasts over 200,000 trail maps that include photos and reviews. AllTrails' UI makes it easy to explore and search trails, and there's a multitude of filter options such as difficulty level and dog-friendliness. Plus, with your GPS on, you can record your route - including pace, distance, elevation and save it or share with friends. For backcountry hikers there's also a pro version that lets you use routes offline.

Like AllTrails, Hiking Project is a crowdsourced database of trails and hiking information. It too has trail reviews, photos and general info about the hikes like distance, difficulty, dog/family friendliness etc. Hiking Project doesn't have as many trails as AllTrails mapped out (76,000) but perhaps it makes up for that with its detailed descriptions of each trail that makes the app feel like a guidebook. Plus, unlike AllTrails, the Hiking Project's offline functionality is a free part of the app

Guthook has all of the usual trappings of a navigation app: GPS tracking, detailed maps, offline capabilities, etc. But its features were designed specifically for thru-hikers, bringing long-distance hiking into the digital age. Hikers can send updates and share locations with family and friends, look up necessities like water sources and campsites, and access "town guides" which have info that all thru-hikers need to resupply and get back on the trail.

Price: Free to download, but specific trail guides must be purchased

What sets Spyglass apart from other navigation apps out there is its augmented reality technology. The app overlays a military grade compass that is fine-tuned by your phone's GPS, gyroscopic sensors and accelerometer. Spyglass also features a rangefinder to measure distance, a sextant, and an inclinometer for measuring steepness. And when you're done pretending to be Rambo, Spyglass can also store the location of where you parked your car.

This app is pretty new to the scene, but has received great reviews so far. As anyone who has been in the outdoors before knows, things can go wrong, and sometimes professional help is far away. This app helps you assess the emergency with a series of questions and then helps you treat and stabilize with wilderness first aid techniques. The app is also loaded with more general survival and first aid information, so you can be well-prepped for your next big adventure.

While hiking is all about enjoying nature, this app actually helps you identify it.

A joint initiative by the California Academy of Sciences and the National Geographic Society, Seek is designed for kids and families. But really, it's for anyone who wants to learn more about flora and fauna.

There are lots of great stargazing apps out there, but this one wins out for its beautiful augmented reality design. Point your device at the sky, and the app identifies planets and superimposes beautiful constellations. Sky Guide will also send you notifications of satellite sightings, astronomy news, and alert you to upcoming astronomical events. And since the best backcountry stargazing often coincides with bad cell service, the app works offline too.
