When distance grows,
connections glow.
A bracelet that reads your pulse and transmits it to the person you love most — lighting up in the rhythm of their heart, no matter the distance between you.

Three heartbeats apart
No screens. No notifications. Just the quiet pulse of someone who loves you.
It reads you
A medical-grade PPG sensor rests against your skin, measuring your pulse with every beat. No buttons. No setup. Just wear it and it knows.
It crosses the distance
Your heartbeat travels — bracelet to phone, phone to cloud, cloud to their phone, their phone to their bracelet. The whole journey takes less than a second.
It glows for them
Their bracelet lights up in the exact rhythm of your heart. Not a notification. Not a buzz. A warm, living glow that says: I'm here. I'm alive. I'm yours.
"It's not a light.
It's a presence."
The amber pulse isn't a notification — it's the actual cardiac rhythm of someone you love, translated into light. Soft enough to catch in a dark room. Warm enough to feel like they're next to you. Each beat ramps up smoothly and fades down, mirroring the waveform of a real heartbeat. It doesn't flash. It breathes.
Closer than a phone call
Because sometimes you don't need words. You just need to know they're there.
"I'd look down at my wrist in the middle of the night and see it glowing. I didn't need her to call. I could feel her sleeping."
"During finals I'd be in the library at 3am and the glow would pick up — he was waking up in Barcelona. It made me feel less alone."
"My daughter got me one when she moved to New York. I wear it every day to feel her presence."
Everything you need to know
Everglow uses a PPG (photoplethysmography) sensor — the same technology in the Apple Watch and Oura Ring. A tiny light shines against your skin and a sensor reads the blood flow changes with each heartbeat. It's completely passive. No buttons, no interaction needed.
The bracelet transmits the rhythm — the pattern and pace of your heartbeat — not the clinical BPM number. Their bracelet glows faster when your heart beats faster, slower when it slows. It's designed to feel human, not medical.
Anywhere with an internet connection. Your bracelet connects to your phone via Bluetooth, and your phone relays the signal over the internet. Durham to Dubai. New York to Tokyo. As long as both phones have a signal, the heartbeats travel.
Absolutely. Your heartbeat data is end-to-end encrypted and only shared with your paired partner. We never store your biometric data on our servers — it passes through in real-time and is never logged. Your heartbeat belongs to you and the person you choose to share it with.
2–3 days on a single charge with typical use. The bracelet intelligently duty-cycles the sensor — reading your pulse periodically rather than continuously — to maximize battery life without losing the feeling of real-time connection. Charges via a magnetic cradle in about an hour.
IP67 rated — it handles rain, handwashing, and sweat without issue. We don't recommend swimming with it, but everyday water exposure is no problem.
