Maybe I'm a luddite, but I value basic skills. I had a chap I was instructing a while ago, a fairly experienced PPL, navigating using Skydemon on an iPad - and 10 miles from his usual home airfield, the battery went flat. He was incapable of working out where he was, and declared himself lost. He then got so stressed, even after I pointed out how to get back to the overhead of his normal club airfield, that he lost control of the aircraft in the overhead requiring me to take control before he spiral dived the pair of us into the middle of the circuit.
Not me, but I was around a training airfield in the USA a couple of years ago where somebody failed their IR because they were flying with an iPad, it overheated in the Florida sun and shut down, and he had no paper backup from which he could complete the flight. Was me, a few years ago I picked an aeroplane up from Madrid to fly back to the UK for a flying school, and discovered that the old owner had been a bit untruthful about the condition of the nav kit, and the power socket didn't work so I couldn't run my portable Garmin for more than about half of every leg: I flew the length of Europe safely on basic instruments, a mode A transponder, paper charts and a PLOG.
I use these gadgets myself, and they're great. I do my flight planning on Skydemon as often as not, and I'm used to flying with various Garmin kit in the air. But I am very very nervous of ever allowing my fundamental skills to degrade, or that of anybody I'm responsible for. And I'm guessing that you have less than 100hrs, you're a complete beginner - yes, use these tools and be good with them, but concentrate in the short term on basic skills as well. Running a couple of simple nav trips on a paper PLOG is not expertise, it's basic exposure.
