■ The catch — co-equal billing, always
Your data never leaves Lingo's app. No Apple Health, no Oura, no sharing with a doctor — Stelo is the only OTC CGM that does any of that. If you plan to overlay glucose on your sleep and workouts, $49 buys you a dead end.

The 15-day sensor that isn't
A Dexcom-funded study found only 77.9% of Stelo sensors lasted the full 15 days. Budget for 10–20% sensor loss before you trust anyone's cost-per-day math.
No alarms at any price
OTC sensors are cleared only for adults 18+ not taking insulin and have no high/low alerts. Anyone dosing insulin needs a prescription CGM — these are screening tools, not medical devices.
Insurance covers none of it
Non-diabetic CGM use is generally not covered by insurance, and Amazon prices track 5–15% above direct subscription pricing. This is a monthly habit, not a one-time buy.
