- App Experience
The Lumen app experience is important for teaching long-term health skills.
The Lumen Metabolism Tracker is a pocket-sized breath analyzer that measures CO2 in a single exhale to tell whether you're burning fat or carbs. Its app then delivers daily personalized nutrition and macro plans.
From current evidence, Lumen Metabolism Tracker is a better fit for users wanting personalized nutrition guidance based on real-time metabolism data. Its app experience teaches long-term health skills while the device is very easy to use and charge. The main tradeoff is the limited evidence available, so long-term reliability remains unconfirmed.
