I don't find it causes friction. I keep a good old Pooleys blue covered log book I have had since my first flight in 1990 (about 700 hours ago), I use SkyDemon for my flight planning and it plus a 1:500 K chart for Nav (also foreflight and an old sectional when I am in the USA) my club has an internet booking system (quite clunky) and there is consultation about whether we really need it
For my license, my PPL won't expire any time soon and I can easily remember that my 2 years expires next April and I need to get an hour with an instructor some time before then. My medical declaration is good or a couple of years yet
I don't find it hard or stressful at all to have 4 (or 5) sources of my info..
