Our biosensor promise
If your sensor stops working within
14 days, we'll replace it.
Stuff happens — bumps, breaks, app hiccups. Whatever the reason, whether it's your first or your fortieth, if your biosensor stops working before you've used it for 14 days, we'll replace it.
How to get a replacement
- Call us 1-888-764-7684
- Or click here to message our support team.
We're available from 9AM-9PM Eastern Time, 7 days a week.
We’ll ask a few questions to understand what went wrong and how we can improve, then send you a new biosensor so you can keep tracking.
