HUMAN COACHING
A 1:1 registered dietitian on every plan — no other consumer CGM service includes RD coaching as standard.
UNDER $250
$149/mo on the 6-month plan, sensors included — $101 of headroom.
COSTS YOU LESS
Plans are HSA/FSA eligible, and 95% of users pay $0 for the dietitian video calls — insurance covers them.
ACCURATE SENSOR
Runs Stelo biosensors — the same 8.3% MARD, 15-day hardware as the category's #1 OTC pick.
CHEAPER PATH LATER
A bring-your-own-sensor tier at $39/mo once you're buying Stelo on Amazon yourself — the coaching without the bundle.
LOGS YOUR FOOD
Syncs with Apple Health and MyFitnessPal — glucose overlaid on what you actually ate.

  The catch — co-equal billing, always

You're renting a dietitian, not better hardware. It's the same Stelo sensor you can buy on Amazon for $99 — the extra $50/mo is the human. And $149 is the 6-month rate; shorter plans run up to $215/mo.

Dealbreaker? Runner-up №2 is the same Stelo sensor, $50/mo cheaper ↓

  Every product has a catch. Verdicts that hide it are how bad buys happen.

Traps — this verdict avoids

Trap 01

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.

Trap 02

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.

Trap 03

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.
