Stelo or Lingo: compare the plan before the glucose graph
Both offer OTC glucose feedback. Eligibility, supply periods and renewal rules shape the purchase.
Compare the same purpose
Stelo and Lingo provide glucose-sensor feedback for eligible adults not using insulin. Neither purchase should be treated as a diagnostic assessment or a promise of longer life. Begin by deciding whether the question is general pattern observation or a clinical concern. The latter needs an appropriate clinician and testing pathway rather than a contest between app graphs.
Choose on access, purchase duration and return conditions before comparing the app graphs. Those differences are concrete; app appearance does not establish better sensor accuracy. The most useful product is the one whose current labeling fits your situation and whose service conditions you understand.
Supply duration changes the budget
Stelo's current US purchase page lists $99 for a one-time two-sensor order, $89 for a recurring monthly order and $252 for a recurring three-month order. Lingo lists a $54 two-week plan, an $89 four-week plan and $249 for a renewing 12-week subscription. These amounts describe different coverage periods and commitments.
Four weeks is 28 days, while a calendar month averages longer. Likewise, 12 weeks is not the same interval as three calendar months. Do not label the two $89 offers equivalent annual costs without accounting for timing. Use the actual shipment schedule, tax and any gaps in wear when building a budget.
Maximum wear is not guaranteed wear
The manufacturers describe up to 15-day sensors for Stelo and 14-day sensors for Lingo, while acknowledging that some sensors stop earlier. Read the replacement policy and keep purchase details available. Also verify your precise phone and operating-system compatibility before placing an order; app availability alone does not establish compatibility with every device.
Stelo's sales page says sales are final and describes replacement for validated issues. Lingo advertises a money-back guarantee subject to its conditions. A return policy and a malfunction replacement are different protections, so check the process that applies to your concern.
Decide how the information will be used
A graph may make patterns visible, but an individual peak is not a diagnosis and a flatter line does not measure overall nutritional quality. Choose a limited question, preserve meal and activity context and avoid changing medication based on app output. Read each product's exclusions rather than assuming OTC availability means unrestricted use.
For a short experiment, compare nonrenewing options first. For ongoing use, assess whether repeated purchases are adding useful information. Our CGM guide explains healthy reference data and why routine clinical diabetes screening remains a different question. Neither an attractive subscription discount nor a detailed weekly report supplies evidence that continuous monitoring benefits every adult without diabetes.
