GPS vs Phone App for Navigation: What's best?

Is a smartphone navigation app good enough or do you need an expensive GPS device for your outdoor trips?

Excellent, thank you! We have been depending on our Apple iPhone for navigation for years and it has been excellent. In the past we would download an offline map that we had to pay for but Apple updated iOS some time ago so you now have a download-map option which eliminates that cost. For serious mountaineers they might still want to buy a dedicated topo map app but for us the Apple Maps work just fine. We also like that the Apple iPhone 15 and newer can make phone calls through satellites so if you are out of cell tower range then your Apple iPhone can enable you to call for help via satellite.

Hey, thank you so much for sharing! 😊 Indeed, this is quite a dilemma. Phones are becoming more sophisticated and reliable, but as you said, it all comes down to personal circumstances and the activities each individual does in the wild. For us, having a good, cheap, but reliable topo map on our phones works just fine! Good luck on your adventures, and may we all learn from each other. Peace! ✌️
