Stay in flowe.

Flowe is the open-source firmware and iOS companion app for the pocket-size Xteink X3 e-ink device. It shows only what you need to stay in flow — and blocks the rest.

Block

Block the noise.

Use the Block app — or press the device's side button — and your phone blocks every distracting app until the countdown ends.

Notifications

See only what matters.

You choose what comes through — texts from people, your next meeting. Everything else stays silent.

Priorities

Focus on your priorities.

Nothing else on screen — just your list for today. Mark things done as you finish them.

The app

Start your day with intention.

Each morning, open the companion app and say your priorities in natural language. On-device AI sets your list and syncs it to the device.

Read

Just you and the page.

Read without your phone's distractions. Your library and page position sync from the companion app.

Workout

Focus on your workout.

One key press logs a set. The phone stays wherever you left it.

Sleep

Even the sleep screen keeps you focused.

In sleep mode, it still shows your priorities and your next calendar event.

Privacy

Everything stays on your phone.

No account.

There's nothing to sign up for and nothing to log into. Flowe doesn't know who you are.

On-device AI.

Apple's model parses your priorities on your iPhone. Your words never leave it.

No cloud.

Everything syncs straight from phone to device. There's no server anywhere in between.

The iPhone app
