I'll be purchasing a new lancing diabetes monitor and am looking for one which integrates well with HealthKit. I assume that it would have an IOS app that would get the data via bluetooth and feed it to HealthKit. The only monitor have found so far that seems if it supports it and is covered via insurance (or they give away free) is: Contour Next One (not rated - but rating for other Next products range from good to excellent). However I tried to download the IOS app, and was told it was not available in the U.S. store, just in the Polish store. One Drop is direct to consumer right now so there is no insurance coverage.
