LibreWatch is an iPhone application designed to read blood glucose levels from Abbott's FreeStyle Libre 2 and Libre 3 sensors directly on the Apple Watch. It allows users to conveniently view the data transmitted via LibreLinkUp on their watch face.

This app, developed independently by Denis Labaste, falls under the Lifestyle category with a focus on Health & Fitness. It's important to note that LibreWatch is not affiliated with Abbott, and users are advised not to rely solely on this app for medical treatment decisions. For any uncertainties, users should consult their LibreLink or Libre 3 application, or perform a capillary blood glucose test.
