App Store & Google Play (Beta)

Native apps are in preparation — built on the same codebase via Capacitor, with push notifications, biometric unlock and a “Send to Subsumio” share extension. Currently in beta — store availability follows the hosted-cloud launch.

Push notifications Biometric unlock “Send to Subsumio”

No spam. We will email you once store apps are available.

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

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.

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.

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

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 now. Use it in your next hearing.

Set up in under five minutes. First cited answer the same day — on whatever device is in your hand.
