Log your foods, track your soluble and insoluble split, build a streak. Fibermaxxxing makes the world's most ignored nutrition target impossible to ignore.
Free to download. No account required. iOS coming soon.
What's in the app
Most fibre apps just count grams. We show you the full picture — how much of your daily fibre is soluble (heart health, cholesterol) versus insoluble (gut motility, regularity).
Every food has accurate fibre values per 100g, default serving sizes, and soluble/insoluble percentages. Search by food or browse by category. Pro users can add custom foods.
Jumping straight to your goal causes digestive discomfort. Ramp mode (Pro) starts you at your current intake and adds a small amount each week — giving your gut microbiome time to adapt.
Build your favourite meals from ingredients and save them as a single-tap log entry. "Overnight oats" becomes one tap instead of three foods every morning.
Current streak and personal best, displayed front and centre. The daily goal-met banner makes hitting your target feel like something worth celebrating — because it is.
Star your most-logged foods and recipes. They float to the top of the picker so your oats, chia seeds, and lentils are always one tap away.
The science
Most people tracking fibre treat it as a single number. But fibre isn't one thing — it's two fundamentally different substances with different effects on your body.
Soluble fibre dissolves in water and ferments in the gut, feeding beneficial bacteria, lowering LDL cholesterol, and slowing glucose absorption. Insoluble fibre adds bulk, accelerates transit time, and supports bowel regularity.
A balanced split matters. Fibermaxxxing is the only mainstream app that tracks both — not as an afterthought, but as a first-class metric in the UI.
Dissolves in water. Ferments in the large intestine. Feeds gut bacteria.
Does not dissolve. Adds bulk to stool. Accelerates gut transit.
Oats (55% soluble), chia seeds (80%), psyllium husk (85%), lentils (50%), apples (50%), barley (60%), artichoke (55%). All tracked in Fibermaxxxing with accurate split percentages.
