Obsidian on desktop earned its reputation the hard way - through genuine flexibility and a plugin ecosystem that lets you bend the app into whatever shape your brain needs. The mobile version used to be the embarrassing sibling. That’s no longer true, and it’s worth saying plainly.
The current iOS app is fast, syncs reliably via Obsidian Sync (or iCloud, if you’re willing to tolerate occasional weirdness), and renders most community plugins without issue. The toolbar is customisable. Quick Capture, via the share sheet or a widget, works without opening the full app. For a note-taking tool built by a two-person company, this is not a small achievement.
Where It Still Loses You
The friction isn’t technical anymore - it’s conceptual. Obsidian is built around a mental model that assumes you have time to think about where a note belongs. On desktop, that’s fine. You’re probably already seated, probably already mid-thought. On mobile, you’re standing in a car park trying to capture something before it evaporates.
The default vault structure punishes you for moving fast. If you haven’t set up an inbox folder and a templating system ahead of time, notes accumulate in the root directory like receipts in a coat pocket. The app doesn’t guide you toward better habits - it assumes you arrived with them.
This is a philosophical position Obsidian has always held: it’s a tool, not a system. On desktop, that posture reads as respect for the user. On mobile, it reads as abandonment.

The Sync Tax
Obsidian Sync costs $10/month (or $8 on an annual plan, as of this writing). That’s not outrageous for what it does - end-to-end encrypted, version history included - but it’s the point where a lot of people bounce to Notion or Bear and don’t come back. Bear in particular has earned its mobile reputation; the editor feels native to iOS in a way Obsidian’s still doesn’t quite manage.
Still Worth It, With Conditions
If you already have an Obsidian vault that works for you on desktop, the mobile app is no longer a liability. Set up a single inbox note, pin it, use Quick Capture, and process it later. That workflow holds up.
But if you’re evaluating Obsidian fresh, starting on mobile first - that’s a harder sell than it should be for software this capable.
