Support & FAQ

We respond to every message within one business day. For anything not covered below, contact us.

Sizing

What sizes are available? The SR16 comes in sizes 8, 9, 10, and 11. Every order includes a sizing insert card. If you’re between sizes, size up — the ring should slide on comfortably and sit snug without pinching.

What if my size doesn’t fit? Contact us within 30 days and we’ll exchange it for a different size, subject to availability.

Setup & compatibility

Which app does it use? The free RWFit app, available for iOS and Android. Pair over Bluetooth — no account fees, no subscription.

How do I charge it? Place the ring in the included charging case. A full charge takes about 90 minutes and lasts 4–5 days of typical use (8–10 days standby).

Can I swim with it? Yes — the SR16 is IP68 rated and suitable for swimming and daily wear.

Ordering & delivery

Where do you ship? Currently we ship within the United States. See our Shipping Policy for processing times and delivery estimates.

Can I buy on Amazon instead? Yes — the SR16 is on Amazon with Prime shipping. Buying direct from this store supports us most, and your warranty is identical either way.

Returns & warranty

What does the warranty cover? A 90-day warranty covers manufacturing defects. See the Warranty page for details and how to make a claim.

Is the SR16 a medical device? No. The SR16 provides wellness and activity information for general fitness purposes. It is not intended to diagnose, treat, cure, or prevent any disease or condition.
