RP02 in 10 seconds
• Tracks sleep, HR, HRV, skin temp — automatically
• 3.0g steel. Lighter than your wedding band.
• 5–7 day battery. No nightly charge.
• No subscription. Ever.
• Fits like it was made for you.
Most wearables ask you to keep paying to keep learning about yourself. RP02 doesn't.
So what is a smart ring, really?
It looks like jewelry. It acts like a clinic. Packed inside RP02's 3.0g steel body are medical-grade sensors — primarily PPG optical sensors that shine light into your skin and measure how your blood flows. From that one signal, RP02 reconstructs your resting heart rate, HRV, skin temperature, sleep stages, and daily movement. No nightly charge. No tap-to-start. No guessing. Your body talks; the ring listens.
Why your finger beats your wrist
Smartwatches strap a sensor to bone and muscle. A ring sits on your finger, where skin blood flow is steadier and closer to the surface — which is why ring-based sleep and HRV readings consistently out-track the wrist. You're not trading accuracy for comfort; with RP02 you get both.
Your health, on autopilot — for life
We built RP02 so the data never stops working for you. The moment you put it on, it starts reading: resting heart rate, HRV, skin temperature, sleep stages, and daily movement. All of it flows into the QRing app — with no subscription fee, ever. No tier to unlock. No "premium" to upgrade to. Just open the app and your body is talking back.
3.0g of all-day comfort
A smart ring only works if you forget you're wearing it. RP02 is 3.0g of ultra-light stainless steel — ergonomically shaped, scratch-resistant, weighted to disappear on your hand. Typing, lifting, sleeping, shaking hands: you'll feel it less than your wedding band, and look sharper doing it.
7 days of power, 45 minutes to refill
No one wants a daily charge. RP02 runs 5–7 days on a single charge, and when it finally blinks low, the magnetic charging case tops it up in 45 minutes — extending runtime up to 30 days on the go. Leave the cable at home for the weekend. The ring won't mind.
8 ways it moves with you
Button-free by design, RP02 auto-detects activity across 8+ sports modes — running, cycling, swimming, strength, HIIT, and more — then quietly syncs it all to the app. No taps to start, no modes to toggle. Move, and it knows.
Gift-ready, from the first unboxing
RP02 arrives in premium gift-box packaging with its magnetic charging case and a printed setup guide. Hand it to a dad, a groomsman, or your past-self who kept putting fitness off. The box does the selling; the ring does the rest.
A Tuesday with RP02
7:02 AM — you wake; the ring already scored last night's sleep.
9:30 AM — walked to a meeting; it counted the steps without a tap.
6:15 PM — gym; 8 modes auto-logged the session.
11:20 PM — 45-min top-up in the case. You never opened the app.
That's the whole day. The ring did the rest.
Who is RP02 for?
The guy who wants the number without the noise. Who checks his recovery over his shoulder between meetings. Who'd rather feel his baseline than wonder about it. If you've ever worn a watch to bed and resented it by morning — RP02 is the upgrade you didn't know you were owed.
Your data is yours — not a monthly bill
No caveats: full QR bound app access ships with every RP02. No subscription, no paywall, no fine print. The insights are yours, 24/7, for life. We don't rent your heartbeat back to you — that's the promise a ring keeps that a watch keeps selling.
The bottom line
RP02 is a men's smart ring that tracks daily health, fits like it was made for you, and asks for nothing back — no fees, no fuss, just the full picture of you. 24/7 wellness, lifetime access, zero subscription.
Ready to feel your baseline instead of guessing it? That's the RP02.
