Everything we get asked.

No. Every Aura ring includes lifetime access to the full Aura app and your full data. We do not paywall metrics, scores, or history. There is no monthly fee.

Aura tracks the same core metrics that drive sleep and recovery insight: heart rate, HRV, blood oxygen, skin temperature trends, and sleep stages. The price difference is significant: Aura has no monthly subscription and sits at $239 to $334 instead of $349 plus $5.99/mo. Oura has a more mature ecosystem; Aura is built around useful insight rather than data overload.

About two weeks from order to your door, with tracking. We'll email you a tracking number the day your order leaves the workshop.

U.S. only at the moment. International shipping is on the roadmap. Email reservations@neuralxaura.com to be notified when your country opens up.

Visa, Mastercard, Amex, Discover, Apple Pay, Google Pay, Shop Pay, Klarna, and Affirm. Klarna and Affirm let you split the order over four payments.

Yes, before it ships. After it ships, return it within 30 days for a full refund.

Sizes 6 to 13 (U.S. standard). Take the 60-second sizing quiz, or measure with a string and ruler against the chart on the sizing page.

30-day returns, no questions asked. We'll send the right size at our cost; return the wrong one in the prepaid mailer once your replacement arrives.

Size up. Fingers swell as the day goes on, after meals, and during summer. A snug ring at 9am will fight you by 4pm.

Yes. The outside is flat to the finger and the inside is rounded. Most people forget they are wearing it within a week.

If your size shifts within the first 90 days, email support@neuralxaura.com and we'll swap it for free. After that, the standard return window has closed but we still offer a discounted resize.

Aerospace-grade titanium outer shell. Hypoallergenic medical-grade resin inside the band. Sapphire-coated sensor windows. No exposed nickel.

No. The inner surface is hypoallergenic resin, not metal. People who can't wear stainless steel or rose gold jewelry usually wear Aura without issue.

Water resistant to 50m. You can shower, swim, and wash dishes with it on.

Hot tub yes, briefly. Sauna no — sustained heat above 60°C / 140°F can shorten battery life and weaken the inner seal. Take it off at the door.

No. Wipe it off with a damp cloth when you remember. The finish is engineered to handle daily exposure to the things that touch your hands.

Warm water and a soft cloth. Avoid abrasive sponges, bleach, or jewelry-cleaning solutions. Once a month, a soft toothbrush + dish soap on the inside surface keeps the sensor windows clear.

Matte black hides the most. Brushed silver shows micro-scratches as patina (most owners come to like this). Rose gold sits in the middle. None of the finishes show damage from normal wear within the first year.

Designed and engineered in the U.S. Assembled in Shenzhen at a partner workshop with a manual QC pass before every ring ships.

7-10 days under normal use. Heavy workouts, hot weather, and continuous SpO2 monitoring shorten that to about 5-6 days.

Under an hour from empty to 100%. Most people top it off Sunday morning while making coffee.

The case carries enough reserve to fully recharge the ring two to three times before the case itself needs a USB-C top-up. Useful on longer trips.

The battery is rated for ~3 years of daily use before noticeable degradation. We don't sell user-replaceable batteries today, but our after-warranty service swaps the cell at our cost. Email support to start that.

Multi-channel PPG (heart rate, HRV, blood oxygen), skin-temperature sensor, accelerometer, and a small thermistor for ambient compensation. Aura Pro adds a second PPG channel for cleaner overnight readings.

One daily readiness number, three contributors that drove it (sleep, HRV, recovery), and one short sentence on what that means for today. Plus a clean history view. No streaks, no badges, no paywalled coach.

It takes about 7-10 days for the app to learn your baseline. The first week's numbers will move around. After that they settle.

Yes. Aura tracks sleep when you sleep, not when the clock says you should. The app marks your main sleep window automatically and tracks naps separately.

Apple Health and Google Fit integration are live. Strava and Garmin are on the roadmap. We don't paywall integrations.

Read-only web view at app.neuralxaura.com. Setup and most interactions live in the mobile app.

Yes. CSV and JSON export are in Settings > Privacy. Your data is yours.

Yes. End-to-end encryption between the ring, your phone, and our servers. Stored encrypted at rest. Only you and your account can decrypt it.

No. We don't sell or share customer health data. Period. Read the privacy policy for the legal version.

Yes. Settings > Privacy > Delete my account permanently wipes all stored data within 30 days. We don't keep a backup.

2-year limited hardware warranty. Battery health is included. We cover defects, not user-caused damage like impact fractures.

Manufacturing defects, sensor failure, battery degradation beyond ~30% in the first 2 years, and finish issues that aren't the result of impact. We send a replacement and a prepaid return mailer.

We still service it. Out-of-warranty repair pricing lives at /pages/support. Battery swaps run about $39 plus shipping.

Email support@neuralxaura.com with your order number and a photo. Most replacements ship the next business day.

Yes. The Aura app is on iOS 15+ and Android 11+.
