A phone with useful apps installed can save your hike. Sometimes, it can even save your life. It’s best to install apps at home, before you lose signal.
So, what are the best hiking apps? These apps serve four purposes: navigation, plant identification, weather, and first aid. If you master these four functions, you’ll be protected from most problems on the trail. Below are 10 apps worthy of a place on your home screen.
If you lose your trail, you can turn a fun day into a search and rescue mission. GPS apps track where you’ve been and show you the way back. Good apps continue to work even without cellular service. The main thing is to download a map of your desired area while you have a Wi-Fi connection.
Gaia GPS
Gaia GPS is the first choice for backpackers who like to travel off-road. It’s among good hiking apps, specifically designed for areas without cell service. You can overlay map layers: USGS topographic maps, Forest Service roads, satellite imagery, even boundaries between private and public lands.
Hunters, hikers, and backcountry skiers use it extensively. The free version covers the basics, while Premium unlocks more advanced features.
AllTrails
This application is powered by collective knowledge. AllTrails lists 500,000+ trails, each with reviews, photos, and recent trip reports. You can filter them by distance, elevation gain, dog walking regulations, or stroller accessibility.
Upgrade to AllTrails+ for offline maps, wrong-turn alerts, and real-time location sharing. This app is great for choosing a route you haven’t taken before.
CalTopo
CalTopo is a tool for map lovers, in the best sense of the word. Search-and-rescue teams and avalanche forecasters use it to plot routes. The slope-based shading feature lets you identify steep and landslide-prone terrain before you even set foot on it.
You can overlay data and then export a PDF file for printing. It takes some time to master, so experiment with it at home.
Nature Identification Apps
Half the plants along the trail are unfamiliar. Some are worth picking; others can make you itch for a week. Your phone can name them before your skin even notices.
BotanApp
Point your camera at a plant, and Botan will identify it in seconds. For plant lovers, this is the best app for hiking trails full of greenery. It compares your photo to 30,000+ species, with a claimed accuracy of about 98%.
On the trail, the berry identifier from Botan will help you distinguish a good handful from a bad one. As a bonus, here’s what else it can do:
- Keeps a personal gardening journal of your finds
- Shows whether a plant is toxic to people or pets
- Detect diseases and pests from a photo if you grow plants at home
- Read light levels with a built-in light meter
- Notify you when your plant needs water or fertilizer
One caveat: this is a program for identifying and caring for plants, not a scientific database. However, for the inquisitive traveler, it’s the best trails app companion for finding safe routes when the flora seems confusing.
iNaturalist
iNaturalist relies on real naturalists, not just an algorithm. You post a photo, the system suggests an identification of a tree, herb, or flower, and then people confirm or correct it. These entries don’t go to waste — scientists use them for biodiversity research through databases like GBIF.
iNaturalist also has a Seek version, a lighter release that is designed for children and doesn’t require authorization.
Weather Forecasting Apps
Mountain weather changes quickly — a clear morning can give way to thunderstorms by midday. Reliable hiking trail apps will warn you before the first drop of rain. Check the weather the night before, then verify it again at the start of your hike.
Windy
Windy turns forecasts into an interactive map that you can actually read. Wind, gusts, rain, temperature, and storm risk are all layered separately. It uses data from multiple models, including ECMWF, GFS, and ICON, so you can compare them. Click on any point to get an hourly summary.
AccuWeather
If you’re looking for simple and reliable weather forecasting software, AccuWeather is a great solution. MinuteCast tells you when rain starts and ends, down to the minute and two hours in advance.
RealFeel takes wind and humidity into account, so you know what your body temperature will actually feel like. Severe weather warnings arrive quickly and help you time them correctly.
Emergency Survival Apps
Sometimes you can get injured while hiking. A sprained ankle three miles from your car can change your whole day. These apps will help you cope when help isn’t available. Install them at home, because your life may depend on them.
Red Cross First Aid
The American Red Cross has created a great app for first aid. Clear steps will help you cope with bleeding, burns, broken bones, and choking. Short videos accompany the text, and it all works offline. It’s free, with quizzes to help you remember the steps.
Offline Survival Manual
This app puts a survival library on your phone. Shelter, water, fire, foraging, and first aid — all the guides are inside. Everything opens even at zero signal, exactly when you need it. It’s free, primarily an Android tool, so browse a few pages of the app beforehand to find them quickly in a possible difficult situation.
Cairn
Cairn is less about maps and more about letting people know where you are. It displays reported cell coverage, so you’ll know where to find the next signal. Share your route and return time, and your contacts will receive an alert if you’re delayed.

Conclusion
