Best CGM for testing food and exercise
As of August 2026 the Abbott Lingo ranks first of 6 devices we track here, at $54.00 to try.
Ranked by how often the sensor reads, then by what periodic testing costs. Reading frequency decides whether you actually see a meal spike: a sensor reporting every 15 minutes can blur or miss the peak entirely, while one reading every minute shows its shape.

Four inputs change what a sensor shows you. The evidence behind them is not equally strong, and the one with the best evidence is the one people expect least.
