It's been working for him for twelve years. I think that's pretty practical.
App require maintenance and are out of your control; right now a chunk of my personal process is a mess because some stuff depended on Evernote. Which was great for about a decade until it got a complete rewrite as an Electron app, and now it's super slow and keeps adding new "friendly" stuff that gets in between me and my notes. I haven't found a replacement that's not full of its own problems and it's impossible to downgrade to the old, perfectly functional native apps on the iThings (and eventually an OS update will break all the apps), it's incredibly frustrating. The parts of my process that depend on writing stuff down in a paper journal, meanwhile, continue to work exactly the same.
