Support this work<br>SugarTrack is the first of several planned apps for health and lifestyle tracking — all offline, all on-device, and built around problems people actually face. No accounts, no cloud, and no subscriptions.<br>If this project is useful to you, starring the repository on GitHub is a simple way to show support. It also helps make the case for building more tools in the same spirit.<br>Star on GitHub<br>SugarTrack is a logbook, not a glucose meter and not medical advice. Readings come from your own meter.
