That seems like a dangerous trend. The lesson here appears to be "Don't bother learning important or useful survival information ... just bring your i-phone with the appropriate apps and you'll be alright." Nothing wrong with improvising and using what's available to survive and nothing inherently wrong with technology but you must also learn to recognize its limitations. You have to learn the basics first and then when using the technology you will more easily recognize its limitations (and not take it for granted the technology will always be right). Case in point: I made it through college level Calculus I and Calculus II without a graphing calculator, just a basic Texas Instruments scientific calculator. After learning the basics and eventually getting a graphing calculator I was then able to recognize the limitations of the technology. No relevance, just an example. FWIW.
