Your journey, our
biosensor promise

We are with you every day of your Lingo experience, no matter what. Life with a biosensor on your arm takes some getting used to. Bumps and breaks can happen. Phones and apps can also disconnect. 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.
