Recommend trying Microsoft's Onenote. It works fantastic on Android, iOS, and PC, been using it for years and it finally replaced everything else I used to use, including Evernote and Google Keep.

It also kind of depends how you plan to use the app. For example, if I were just doing short little checklists, reminders, brief unrelated scraps of info, etc., Google Keep is great at that and easy to use. If you need a more complex, note-taking app in which you can structure the content with a visual/logical layout, and with tags, you probably want something like Onenote. It's great for academics, for collecting research from many sources, for writing, and for collaborating among teams (multiple team members and view and collaboratively edit the same page at the same time). I basically use Onenote now for everything. I add Onenote web clipper add-in's to the Chrome and Firefox browsers I use, this lets me clip all or part of any web article (the URL, or the actual contents) directly to my Onenote notebook in the cloud, which then auto-syncs across all my devices.
