Store availability follows the hosted-cloud launch (Apple requires a full account flow for review). Install the web app above today — it's the same product, and your account carries over.

Install questions

Is the installed app different from the website?

Same product, same account, same data. The install gives you a full-screen window, a home-screen icon, and an offline fallback. Native store versions will add push notifications and share extensions.

Does it work offline?

The app shell loads offline and tells you clearly when it can't reach your brain. Queries need a connection — your brain lives on your server or your EU cloud instance, not on the phone.

Is the mobile app secure?

It's the same hardened web app: encrypted transport, httpOnly session cookies, and your data never stored on the device beyond the session.

When do the store apps arrive?

After the hosted cloud is live — Apple's review requires a complete signup flow. The Capacitor build setup is already in the repository (mobile/README.md).

Install it now, thank yourself in the next meeting.

Set up in minutes, first answer the same day — on whatever device is in your hand.
