Notion vs Obsidian: which to choose

Both makers declare a free plan, and both list iOS, Android, Windows and macOS. Obsidian also declares Linux; Notion's entry does not. A platform missing from a maker's list isn't proof the app won't run there. It just means no verified declaration to show you.

Start from the device you actually write on. If you read notes on your phone and write on a laptop, check both entries before you commit. I haven't tested either app, so every platform claim here comes from the makers, not from me.

Begin with where you write and where you read: computer, phone, or both. If you're replacing an app, read its documentation on exporting existing notes before you compare anything else. Moving years of notes is the step people regret skipping.

Being available on two devices doesn't prove that syncing between them is free. Treat those as separate questions and check each one on the official source.

Notion's maker declares iOS, Android, Windows and macOS, plus a free plan. That declaration doesn't say which features the free plan includes. Open the source and read the requirements for your device's version before you decide.

If Linux matters to you, Notion's entry doesn't list it. That's a gap in the verified facts, not a verdict on the app.

Obsidian's maker declares iOS, Android, Windows, macOS and Linux, plus a free plan. As with Notion, the declaration doesn't establish what the free plan covers. Check the source for your device's requirements.

Linux is the one platform where the two entries differ. If you work across a desktop and a phone, confirm both before you install.

These are three different things, and mixing them up costs money. Check the official price list for the limits of the plan you want. Then confirm whether payment is monthly, yearly or one-time.

A price that isn't listed stays unverified; it doesn't become zero. Listed prices apply to the selected market only, so the same app may not cost the same everywhere.

Before moving important data, read the official documentation on export, sync and offline access. If those features aren't in the verified facts, this guide doesn't credit either app with them. Also check the interface language and your country's store terms.

The right pick depends on your task and your devices, not on the lowest price alone. Download from the official site or your platform's store, and confirm the plan details there before you pay.
