Hey! I’ve tried a few different notes apps that could work well for what you're looking for. Notion is a favorite of mine because it's super customizable. You can organize notes however you like, and it has great categorization and tagging features. It syncs across devices seamlessly, so you can access everything from your phone, tablet, or computer. It’s also really useful for both quick notes and more detailed journal entries or creative writing.

Evernote is another solid option that I’ve used for years. It’s reliable for syncing notes across devices and offers a clean interface for keeping things organized. It’s especially good if you want to separate things into notebooks, and the tagging feature works well for grouping related ideas.

Finally, if you're into brainstorming and connecting ideas in a more visual way, Obsidian might be worth checking out. It’s fantastic for creative writing since you can link your ideas together in a more dynamic way, almost like building your own personal knowledge base.

All three have easy-to-use interfaces and should help keep everything organized while offering flexibility for different types of notes!
