A phone that does everything

Everything.
Nothing extra.

A full-capability smartphone that reshapes behaviour through friction and defaults. Not a dumb phone. A deliberate one.

The problem

Screen time apps rely on willpower. Dumb phones remove capability. Neither works.

How it works

Three layers of intentional access

Tier 1

Calls, messages, maps, music, camera, email. Native. Instant. Zero friction. These are why you keep this phone.

Tier 2

Social media through controlled wrappers. Instagram without the feed. YouTube without autoplay. The utility without the trap.

Tier 3

Any Android app. Full Play Store. Banking, rideshare, work tools. Available when needed, behind deliberate friction.


AI Agent

Say it. Done.

The agent understands natural language and executes via Android intents. No app opening. No browsing. No rabbit holes. 25 intent types. 12 app wrappers. Constrained execution — the agent acts only through verified intents.

Why Kern

Every competitor either removes capability or relies on willpower. We do neither.

Physical keyboard

BlackBerry-style QWERTY. Every navigation step is a conscious choice. You cannot mindlessly scroll with directional keys.

Notification batching

Only calls and direct messages interrupt. Everything else is batched and delivered on your schedule, not the app's.

No lock-in

Standard protocols. CardDAV, CalDAV, IMAP. No mandatory accounts. No vendor dependency. Your data stays yours.

Privacy-first

No Google services by default. On-device AI processing. Cloud is opt-in. The phone listens when you tell it to. Never otherwise.
