Notion: notes, databases and wiki in one workspace
The most popular app in the category with 89,920 ratings. It replaces several tools at once, and costs 566 MB and a learning curve for it.
Notion is the most popular app in this category by a distance: 89,920 ratings at 4.8. It is also the least like a notes app.
What you actually get
A building kit. Pages contain blocks, blocks can be tables, tables can be filtered views of other pages. People run entire companies inside it — project trackers, documentation, hiring pipelines.
For a team, that is the point: one place instead of five subscriptions.
What it costs you
Time before it works. A blank Notion is not a notebook, it is a construction site. Most people spend the first week building a system instead of writing.
566 MB — the largest app here, fifteen times Obsidian.
Speed on large workspaces. Loading is noticeable once you have hundreds of pages, and offline support has always been the weakest part.
Who should skip it
Anyone who wants to open an app and type. That is a real and common need, and Notion serves it worse than a text field would.
