Unlike its prescription-only sibling, the G7, Stelo doesn't require a prescription, and it's not intended for people on insulin. It's about the size of a quarter with tiny prongs that go just under the skin and are essentially painless. Once applied, Stelo pairs with your phone and delivers glucose readings every 15 minutes. That's less frequent than prescription CGMs, but more than enough to show how food, activity, sleep and stress affect your glucose.
