Stelo by Dexcom vs Lingo by Abbott

Stelo by Dexcom vs Lingo by Abbott (2026)

Stelo and Lingo are the two FDA-cleared over-the-counter CGMs in the US — the first consumer glucose monitors you can buy without a prescription. Stelo runs on Dexcom G7; Lingo runs on Abbott Libre 3. Both are OTC, both target non-diabetic biohackers, and both are deliberately simpler than the coached programmes (Levels, Nutrisense). The choice comes down to warm-up time and wear length versus price flexibility.

Stelo by Dexcom or Lingo by Abbott: which is better?

Practically equal by ONDA score (7.5 and 7.5)

Stelo wins on warm-up time and wear length at a small price premium. Lingo wins on cost flexibility — buy single 2-week sensors as needed without subscription.

Head-to-head breakdown

Stelo by Dexcom vs Lingo by Abbott — head-to-head comparison by criterion
Criterion	Winner	Why
Sensor accuracy	Tie	Practically equal: maker accuracy figures do not count as evidence, and in an independent head-to-head study (Eichenlaub et al. 2025) the Dexcom G7 platform and FreeStyle Libre 3 were similarly accurate (MARD about 12% vs 11.6% against a lab reference).
Sensor wear time	Stelo by Dexcom	Stelo: 15-day wear (longer than standard Dexcom G7). Lingo: 14 days. Tie in practice; slight Stelo edge.
Warm-up time	Stelo by Dexcom	Stelo: 30 minutes. Lingo: 60 minutes. Stelo back on data faster after each sensor swap.
Insight depth	Stelo by Dexcom	Stelo: meal-impact + daily time-in-range. Lingo: single "Lingo Count" spike score per meal — deliberately beginner-simple.
Price flexibility	Lingo by Abbott	Lingo: $54 per single 2-week sensor, with multi-sensor plans lowering the per-sensor cost. Stelo: $99 for two sensors (~30 days) or $89/month on subscription.
No subscription required	Lingo by Abbott	Lingo: full functionality with single sensors, no subscription. Stelo: hardware works without subscription but the monthly purchase pattern is the default flow.
App ecosystem	Tie	Both have clean iOS/Android apps with Apple Health integration. Limited third-party connectors compared with Levels.

Choose Stelo by Dexcom

Choose Stelo by Dexcom if a 30-minute warm-up and 15-day wear matter more than the last $50/month — you get the same Dexcom G7 hardware as Levels and Nutrisense at a third of the cost.

Choose Lingo by Abbott

Choose Lingo by Abbott if cost is the deciding factor or you want to wear a CGM occasionally rather than continuously — single 2-week sensors at $54 each.

The short version

Stelo wins on warm-up time and wear length at a small price premium; Lingo wins on cost flexibility for occasional wear. Both are OTC — no prescription, no coaching subscription — which sets them apart from Levels, Nutrisense, Signos and the rest of the premium-tier CGM market.

When is Stelo the right pick?

If you want the Dexcom G7 sensor — the same one underneath Levels and Nutrisense — at roughly a third of those programmes’ cost, Stelo is the right shape. The 30-minute warm-up versus Lingo’s 60-minute matters more than it sounds when you swap sensors every two weeks.

When is Lingo the right pick?

If you are not sure CGM will change anything for you and want the cheapest legitimate way to find out, or you plan to wear a CGM occasionally rather than continuously, Lingo is the right shape. $54 single sensors with no subscription beats Stelo’s monthly model on flexibility.

Common questions

Is Stelo more accurate than Lingo?

Not meaningfully. Stelo runs Dexcom G7 and Lingo runs Abbott Libre 3. The makers report different figures (about 8.2% MARD for G7, about 9% for Libre 3), but maker figures do not count as evidence in ONDA scores; in an independent head-to-head study (Eichenlaub et al. 2025) the two were similarly accurate. For most non-diabetic biohacker use cases both are accurate enough.

Which is cheaper, Stelo or Lingo?

Lingo is cheaper at the single-sensor entry tier — $54 per 2-week sensor, with multi-sensor plans lowering the per-sensor cost. Stelo is $99 for two sensors (~30 days) or $89/month on subscription. If you want to wear a CGM continuously, the gap closes; for occasional use Lingo wins on cost flexibility.

Do either require a prescription?

No. Both Stelo and Lingo were FDA-cleared as OTC consumer CGMs in 2024 — the first non-prescription CGMs available in the US. You buy them directly from the manufacturer.

Can I get Stelo or Lingo data into Levels or Nutrisense?

No, not directly. Each programme is hardware-locked to its own app. The underlying sensors are the same physical hardware (Stelo = Dexcom G7 platform = Levels, which now ships Stelo, and Nutrisense; Lingo = Libre 3 = Ultrahuman/Veri/Zoe) but the apps do not cross-read each other’s sensors.
