Intermittent Fasting Tracker
That Talks to Your Macros
Most fasting apps track your eating window. Macro Maxxing does that and integrates with your daily macro tracking — so you know exactly what to eat during your feeding window.
Why Fasting + Macros Together?
Intermittent fasting restricts when you eat. Macro tracking controls what you eat. Together, they're the most effective combination for body composition — but most apps make you use two separate tools.
Macro Maxxing is the only app that combines a persistent fasting timer with AI-powered macro tracking in one interface.
