OneNote stands out as the premier free digital note-taking app. Since becoming fully free in early 2015, it has packed in even more powerful features, outshining competitors like Evernote. OneNote is now truly free with more features than before. While some prefer Evernote, our in-depth comparison shows why OneNote often wins.

On Windows, you'll encounter two free versions: the OneNote 2016 standalone desktop app and the OneNote app from the Microsoft Store (a Universal Windows Platform or UWP app). As a long-time OneNote user across devices, I've tested both extensively. Here's a breakdown to help you decide. Confused by Windows app terminology?
The Store app gets flak for its stripped-down look, but I appreciate its clean, modern design aligned with other UWP apps. It's space-efficient, with most formatting tools at your fingertips—ideal for tablets like the Surface Pro.

That said, it lacks non-paragraph styles (e.g., headings, bullets), clear formatting, and format painter. Drawing tools are more limited too. Both share core organization: notebooks, sections, pages, and subpages. However, the Store app doesn't support bulk actions for moving or deleting notes.

The Store app defaults to "Recent Notes," but right-click any note and select Go to Note Location, or pick a notebook from the sidebar. It's optimized for touch and mobility—a smart tradeoff for simplicity.
The Store app shines for basics but misses OneNote's standout tools. 7 Popular OneNote Features You'll Love.
Shared features include:

Desktop exclusives:
The desktop app offers deep customization, while the Store app has minimal options—typical of UWP vs. desktop. Desktop vs. Windows Store Apps.

Store settings: Auto-sync notebooks/files/images, Sticky Notes default, and minor privacy tweaks.

Desktop includes save/backup locations (How to never lose a note in OneNote) and more.
OneNote 2016 is superior for power users—think Evernote-level functionality. The Store app suits light, Google Keep-style needs. On desktop, go with 2016 (no Office purchase needed—Don't buy Office 2016!).
