Get Vurro on your phone

A complete Substack chat client for iOS and Android — threads, search, bookmarks, watched users, reactions, and read-state tracking. It already does things the native chat can't; it's in beta simply because of how it's distributed today, so there are a few quick setup steps.

Vurro for mobile is ready for everyday use — the beta label is about distribution, not polish. On Android, Google requires a minimum number of active testers before an app can move to a public release, so joining genuinely helps it get there. On iOS, it's delivered through TestFlight while it finishes store review.

Substack chat is great — until it isn't

Popular chats move fast. Messages pile up, threads get buried, and finding that one post from last week? Good luck. Vurro adds the tools Substack hasn't built yet — so the conversations you care about don't get lost in the noise.

What Vurro adds

The chat tools Substack is missing

The same toolkit, on your phone and in your browser.

New

Pick up exactly where you left off

Substack's own apps mark an entire thread read the moment you open it. Vurro tracks what you've actually seen on screen — so when a busy thread has more messages than you can get through in one sitting, close the app and come right back to the first one you haven't read. On by default; mark anything unread whenever you like.

Direct links

Questions

Good to know

How do I get the mobile app?

The mobile app is in beta. On iPhone or iPad, install Apple's TestFlight app and open the Vurro invite link. On Android, join the testers Google Group, then install from Google Play. Full steps are in the Get Vurro on your phone section above.

Is Vurro free?

Yes. The browser extension is completely free, and the mobile app is free during beta and at launch. A Premium tier with fine-grained notification rules — by specific user, replies, or mentions — is planned for later. No ads, no data selling — ever.

Which platforms are supported?

Mobile: iOS (via TestFlight beta) and Android (via Google Play closed testing). Browser: Chrome and Firefox.

Why is the mobile app in beta?

Not because it's unfinished — it's a full-featured client you can use every day. Beta is just how it's distributed right now: through TestFlight on iOS and Google's closed testing on Android. Google also requires a minimum number of active testers before an Android app can move to a public release, so joining directly helps Vurro get there.

Does Vurro collect my data?

No. Vurro runs entirely on your device — the extension in your browser, the app on your phone. It doesn't send your data to vurro.net or anywhere else. See the privacy policy for details.

Is Vurro affiliated with Substack?

No. Vurro is an independent project, not endorsed by or affiliated with Substack.

How do I report a bug or ask a question?

Open an issue on GitHub, or drop into the Vurro subscriber chat for questions and feedback.
