I’ve settled into Simplenote as my primary note taking app, but truthfully, it’s a bit more complicated than that. I use Ulysses for writing that ends up here on Initial Charge, Day One for journaling, Edit for ephemeral notes, Things for notes associated with specific tasks, Apple Notes for collaborating on notes with my wife, and I use Simplenote for everything else.
There isn’t any one app that does everything I want so I’ve ended up with a handful of apps that all loosely serve the purpose of “note taking”. I can understand why someone would want to find the One App to Rule Them All, but I kind of like having a variety of apps instead. It helps me to focus. And I get to fully configure each of the apps so they’re tailored to what I use them for.
