FiberUp is the only fiber tracking app built specifically for fibermaxxing - with a 120+ food database, barcode scanner, daily progress ring, plant count tracking, and weekly views.
Fibermaxxing is the practice of intentionally maximizing your daily dietary fiber intake for better gut health, lower cholesterol, and longer-lasting fullness. Most people eat only 10–15g of fiber a day. Fibermaxxers aim for 30–50g or more - from whole, diverse plant foods.
Dietary fiber feeds the billions of beneficial bacteria in your gut, increasing microbial diversity linked to lower inflammation and better immunity.
Soluble fiber binds to cholesterol in the digestive tract, reducing LDL cholesterol and lowering risk of cardiovascular disease.
Fiber slows glucose absorption, preventing blood sugar spikes and crashes - key for sustained energy and reducing diabetes risk.
Research shows eating 20+ different plant species per week dramatically improves gut health. FiberUp tracks your plant count automatically.
FiberUp is built from the ground up for one thing: helping you hit your fiber goals every single day.
See exactly where you stand against your fiber goal at a glance. Color-coded feedback keeps you motivated throughout the day.

"Finally an app that actually focuses on fiber. Not trying to track everything - just fiber. Love the barcode scanner and the weekly view."
"The plant count feature alone is worth it. I had no idea how many different plants I wasn't eating until I saw the weekly number."
"Clean UI, no bloat. Does exactly what it says. I went from averaging 12g to over 35g of fiber per day in a month."
