Questions? We've got answers.

KEORA tracks sleep quality (deep, light, REM phases), heart rate variability (HRV), blood oxygen saturation (SpO2), stress levels, skin temperature, and daily activity. It monitors your health 24/7, including while you sleep, building a detailed picture of what your body needs.

When you get your ring, we send a free sizing kit with sample rings in every size. Wear the sample for at least 24 hours (including during sleep) to find your perfect fit. It's important to get this right — a well-fitting ring gives more accurate readings.

Yes. KEORA is water-resistant to 50 meters (5 ATM). You can wear it in the shower, pool, or ocean. The only thing we recommend removing it for is very hot environments like saunas above 50°C for extended periods.

Up to 7 days on a single charge, depending on your usage patterns. Charging takes about 60-90 minutes via the included magnetic charger. Most people charge it while they shower in the morning.

KEORA is crafted from lightweight titanium — the same material used in medical implants. It's hypoallergenic, nickel-free, and weighs only 4-6g depending on size. You'll forget you're wearing it.

KEORA works with iOS 15+ and Android 10+ via Bluetooth Low Energy. The companion app syncs automatically when your phone is nearby. No need to manually connect each time.

KEORA offers 5 targeted formulas: SLEEP (5-HTP + L-Theanine), ENERGY (Ashwagandha 600mg), BEAUTY (Biotin + Collagen + Keratin), RECOVERY (Curcumin 95% + Piperine), and WELLNESS (Vitamin C 1000mg + Zinc 15mg). Each is recommended based on your ring data.

Yes. All formulas use natural, well-researched ingredients at clinically studied dosages. They're manufactured in EU-certified facilities, third-party tested, and use vegetable HPMC capsules with rice flour. They contain no artificial colors, flavors, or preservatives.

Each formula has an optimal timing: SLEEP 30 minutes before rest, ENERGY and WELLNESS at breakfast, BEAUTY morning or evening, and RECOVERY after training. The app sends you a reminder at the right time based on your routine.

Yes, the formulas are designed to be complementary. Many members take 2-3 formulas simultaneously. The app will recommend the combination that suits your current health data, and flag any timing considerations.

Your ring data reveals patterns — poor sleep scores suggest SLEEP, elevated stress levels point to ENERGY (Ashwagandha), low recovery scores indicate RECOVERY, and so on. The algorithm analyses at least 7 days of data before making its first recommendation, and adjusts monthly.

Just €1.30/day (€39/month). Your first month is free when you purchase the ring. That covers a 30-day supply of your recommended formula, delivered to your door with free EU shipping.

Absolutely. There's no commitment — cancel or pause your deliveries at any time from your account dashboard. If you cancel, you keep full access to ring features and health tracking. The monthly delivery only covers supplements.

Yes, you can switch your formula at any time before your next shipment. The app may also suggest a different formula as your health data evolves. You're never locked into one formula.

We currently ship throughout the European Union with free standard delivery (3-5 business days). Express delivery is available for an additional fee. We're working on expanding to the UK and Switzerland.

The ring and supplements are designed to work together — the ring provides the data that personalizes your formula recommendation. However, you can take our quiz to get a formula recommendation without a ring, and get supplements on their own.

The KEORA app syncs with your ring to display your health dashboard: sleep score, stress levels, HRV trends, activity, and blood oxygen. It delivers your personalized supplement recommendation, sends timing reminders, and tracks your progress over time.

Your data is yours. We use end-to-end encryption for all health data. We never sell personal data to third parties. All data is stored on EU servers in compliance with GDPR. You can export or delete your data at any time from your account settings.

No. KEORA is a wellness tool, not a medical device. Our ring and supplements are designed to support your daily wellness routine, not diagnose or treat medical conditions. Always consult a healthcare professional for medical concerns.
