AI Companion · Always with you

Your body
holds the truth.
We surface it.

Your heart never lies. We just help you listen. Lumren reads your heart rate, HRV, and stress in real time, plays binaural Hz tones tuned to your state, and breaks the loop before you even feel it — wrapped in an AI that actually knows you. Not a tracker. A companion that sees what you can't.

What is Lumren?

Lum — Light. Ren — Self.

Lumren is the app that brings the light out of yourself — and makes it visible. Your body already carries everything: your energy, your stress, your true emotional state, the rhythms most people never stop to feel. Lumren reads those signals and surfaces them so you can finally see, and be aware of, your true self. Not a label. Not a score. The real you, made visible.

Lum Light

Every person carries an inner light — a unique signal of who they are. Lumren illuminates it.

Ren Self

Awareness of the self is the beginning of everything. Lumren makes your inner world impossible to ignore.

Together

Lumren doesn't track you. It reveals you — turning what was invisible into something you can understand and act on.

Questions

Do I need a credit card to start?+
No. Sign up and you're in. We only ask for payment details on day 3 if you want to continue. Cancel before then and we charge you nothing.
Does the heart scan work without a wearable?+
Yes. Your rear camera detects micro-changes in blood flow through your fingertip, the same technique used in clinical pulse oximeters. 30 seconds is enough to read HRV, stress, and recovery score.
What devices does Lumren work on?+
iOS and Android. Heart rate sync also works with Apple Watch, Garmin, Fitbit, and Wear OS devices if you want continuous monitoring between scans.
Is my health data private?+
Your biometric and emotional data is encrypted on your device before it moves anywhere. We don't sell it, share it, or use it to train models. It's yours.
Can I cancel at any time?+
One tap in the app. No confirmation loops, no email chains, no chat required. Instant.
