Frequently Asked Questions

150AGE uses a proprietary AI algorithm that analyzes 30+ biometric markers collected from your smart ring's sensors while you sleep. These include heart rate variability (HRV), resting heart rate, sleep stages (deep, light, REM), body temperature trends, blood oxygen saturation (SpO2), and movement patterns. The algorithm compares your biometric profile against large population datasets — stratified by age, gender, and lifestyle — to calculate your biological age with 98.7% clinical accuracy. Unlike chronological age (how many years you've been alive), biological age reflects your body's true physiological condition and can improve with lifestyle changes.

Yes. The 150AGE Smart Ring is water-resistant to 100 meters (IP69K rated), making it suitable for swimming, showering, and even hot saunas. The titanium-coated shell and medical-grade silicone inner lining are designed for continuous wear in all conditions. Unlike many smart rings that require removal before water exposure, 150AGE tracks your activity continuously — including swim workouts, where it automatically detects stroke type and lap count.

The 150AGE Smart Ring delivers up to 5 days of continuous operation on a single charge — including 24/7 heart rate monitoring, sleep tracking, and SpO2 measurements. This is achieved through a low-power RISC-V processor and optimized sensor sampling algorithms. Charging takes approximately 60 minutes to reach 80% capacity and 90 minutes for a full charge using the included wireless charging dock. A quick 10-minute charge provides enough power for a full night of sleep tracking.

At just 2.8 grams with a thickness of 2.5mm, the 150AGE Smart Ring is one of the lightest and thinnest smart rings on the market — specifically engineered for sleep comfort. The inner surface is contoured with a subtle ergonomic curve that prevents pressure points, and the hypoallergenic titanium coating eliminates skin irritation even after months of continuous wear. Users report they forget they're wearing it within 2-3 nights.

The 150AGE Smart Ring is available in sizes 6 through 13 (US sizing), covering both men's and women's finger sizes. Each ring ships with a free sizing kit that includes plastic dummy rings in all sizes, so you can wear each size for a full day to determine the best fit before your actual ring arrives. The sizing kit is shipped immediately after you place your order.

The 150AGE Smart Ring features a durable titanium carbide outer shell — the same material used in aerospace engineering and luxury watches — providing exceptional scratch resistance and a premium matte finish available in black, silver, and midnight blue. The inner lining is medical-grade hypoallergenic silicone that prevents skin reactions even with 24/7 wear.

No. 150AGE has zero subscription fees — period. You pay once for the ring at $199 (early access price) and get full access to all features including AI biological age analysis, 24/7 HRV and heart rate tracking, detailed sleep reports with stage analysis, SpO2 monitoring, activity tracking, and personalized health insights. Unlike competitors such as Oura ($5.99/month) or Whoop ($30/month), 150AGE believes your health data belongs to you and there is no paywall to access your own metrics. All future software updates are included free of charge.

We offer a full 30-day money-back guarantee with no restocking fees. If you're not satisfied with your 150AGE Smart Ring for any reason, simply contact our support team within 30 days of delivery to initiate a return. We'll provide a prepaid return shipping label, and once the ring is received in original condition with all accessories, we'll process your full refund within 3-5 business days.

150AGE is currently in its early access phase with limited production batches. Orders placed today are estimated to ship within 2-3 weeks. Once your order ships (with tracking provided via email), delivery typically takes 3-5 business days within the US and 7-12 business days internationally.

Yes, the 150AGE Smart Ring ships to over 50 countries worldwide. International shipping costs $12.99 and includes full customs and duties pre-paid — no surprise fees at delivery. International orders are shipped via DHL Express with full tracking and typically arrive within 5-10 business days after dispatch.

Yes absolutely. Pre-orders and orders that have not yet shipped can be cancelled at no cost. Simply log into your account on 150age.app or contact our support team via email, and we'll process the cancellation and full refund within 2 business days.

Yes. The 150AGE companion app is available for both iOS (iOS 16.0 and newer) and Android (Android 12.0 and newer). The ring connects to your phone via Bluetooth 5.3 Low Energy with a reliable range of up to 15 meters (50 feet). Data syncs automatically in the background whenever the app is open — no manual syncing required. The app requires approximately 150MB of storage for the application itself, with health data stored both locally and optionally synced to our encrypted cloud.

The 150AGE Smart Ring packs five advanced sensors into a 2.5mm thin form factor: (1) A PPG sensor with multi-wavelength LEDs for heart rate and HRV measurement with 96% accuracy, (2) A 3-axis accelerometer for activity and sleep tracking, (3) A precision NTC thermistor for continuous body temperature tracking within 0.1°C accuracy, (4) Red and infrared SpO2 sensor for blood oxygen monitoring during sleep, and (5) An ambient light sensor that automatically adjusts LED brightness.

Absolutely. Privacy by design is core to 150AGE. All health data is encrypted in transit using TLS 1.3 and at rest using AES-256 encryption. We never sell, share, or monetize your personal health data — your biomarkers, sleep patterns, and biological age calculations are yours alone. The app supports full data export in JSON and CSV formats so you can share your data with your healthcare provider if you choose.

Currently, the 150AGE Smart Ring does not directly measure blood pressure using a cuff — no consumer smart ring can perform direct blood pressure measurement. However, our AI algorithm can estimate systolic and diastolic blood pressure trends based on pulse transit time (PTT) analysis from the PPG sensor's photoplethysmography waveform. This provides useful trend data but should not be used as a substitute for medical-grade blood pressure monitoring devices.

The 150AGE sleep staging algorithm has been validated against polysomnography with an overall agreement rate of 87% for sleep/wake detection, 82% for deep sleep identification, and 79% for REM detection — comparable to or exceeding consumer wearables priced at 3-5x the cost. Sleep tracking includes automatic nap detection and detailed morning reports with sleep score, HRV trends, respiratory rate, and SpO2 nadir.

Yes, the 150AGE Smart Ring automatically detects and tracks walking, running, cycling, swimming, and general activity. For swimming specifically, the ring detects stroke type and lap count. While the ring is primarily designed for continuous health monitoring rather than competitive sports tracking, it provides reliable activity metrics that correlate well with dedicated fitness trackers.
