2. Evernote (Free)
Evernote is arguably the most powerful note taking application ever created. It comes with a ton of note taking features including the ability to create lists, insert audio/video/images, and all of that is synced to the cloud where it can be accessed from any web browser. There are also a host of organizational features so you can keep all this info in line. It also features collaboration functionality if you need that and it’s all wrapped up in Material Design. The in-app purchases are for Evernote Premium, which is a subscription that gives you additional features such as PDF annotation, better privacy options, and offline access.
