GotCGM does not currently support Abbott Diabetes Care’s Over-the-Counter (OTC) CGM, the Lingo. Unlike the Dexcom-provided Stelo, there are not yet third-party solutions.
On iOS devices, the Lingo does have the capability to write into Apple HealthKit (AHK) but that won’t be read in real-time by GotCGM due to Apple’s limitations of the AHK datastore.
