One of the principles I teach my students at Arcturus Primitive Skills Institute is this: I am, and always will be, a student.
Take edible and medicinal plants, for example. While I’ve accumulated a substantial amount of knowledge, the learning never ends. There is no way I’ll ever master every single plant’s use on this planet—and that’s the beauty of it. I carry that same mindset into every aspect of survival and bushcraft. Whether it’s new techniques or better tools, I’m always refining, always evolving. What I haven’t learned at formal survival schools, I hunt down on my own.
One of the most effective ways I continue to grow is by leveraging modern apps and digital tools—many of which are available on both iOS and Android. These resources are invaluable to survivalists, bushcrafters, and outdoor enthusiasts alike. Below are some of the most highly rated and useful tools I use and recommend:
PictureThis
A powerful plant identification app that can recognize over 400,000 plant species with more than 98% accuracy. Simply snap a photo of a plant and the app will instantly return its name, species, toxicity warnings, and detailed information. I often use this as a springboard before researching a plant’s edibility and medicinal properties online.
Knots 3D
If you want to master knot-tying, this is your go-to app. It teaches over 200 knots with 3D, 360° interactive views—immensely helpful when trying to understand complex configurations. For a real challenge, try wrapping your brain (and fingers) around the Evenk Hitch.
MyRadar
Skip the clutter of traditional weather apps. MyRadar offers clean, fast, and accurate radar maps with real-time weather alerts—essential before heading into a course with students. It outpaces traditional sources like The Weather Channel or AccuWeather by avoiding distracting pop-ups and advertisements.
Spyglass
A navigation powerhouse that turns your phone into a survival toolkit. With features including offline maps, augmented reality navigation, a digital compass, GPS, waypoint tracking, and even star catalogs, Spyglass is indispensable. When you’ve forgotten your compass or paper map but have your phone (and a reliable power source), this app can guide you through.
Gaia GPS
Perfect for those who prefer a streamlined GPS app. Gaia offers detailed maps and route planning and is known for being more reliable on the trail than its popular competitor, AllTrails. AllTrails excels in route planning, but Gaia shines in execution. I personally prefer Gaia but encourage others to try both and decide which suits them best. Advanced features require a subscription.
First Aid by the American Red Cross
This app could literally save a life. It provides offline access to step-by-step emergency instructions for burns, cuts, CPR, choking, and more. It includes a hospital locator, 911 integration, educational videos, interactive quizzes, and receives regular updates. Best of all—no ads.
Zello Walkie Talkie
Transforms your phone into a real-time push-to-talk radio. With both public and private channels, voice playback, and compatibility across platforms, Zello is bandwidth-efficient and reliable in emergencies. It also supports Bluetooth headsets, offers text and image sharing, and encrypts your messages.
Signal
For secure communication, Signal is unmatched. It uses end-to-end encryption that even the developers can’t access. It’s free, ad-free, and open source. Messages auto-delete based on user settings and are never stored on external servers. It even supports groups of up to 1,000 participants.
SAS Survival Guide
Based on the bestselling book by former SAS soldier John “Lofty” Wiseman, this app offers offline access to practical survival knowledge. It covers essential topics like fire starting, shelter building, Morse code, and sun compass use—ideal for remote adventures.
Pro Tips
• Combine a first aid app with a survival manual app to create a well-rounded emergency preparedness toolkit on your device.
• Organize all your survival apps onto a dedicated home screen. In a high-stress situation, you don’t want to waste time scrolling through icons.
If you’re serious about your self-reliance journey, equipping your phone with these tools can be just as crucial as what you carry in your pack. Let the learning—and the adventure—continue.
