Roughly 95% of Americans don't get enough fiber. Feed Your Gut is built around a simple question: what could you add to the food you already eat?
Take a photo of a meal, scan a barcode, or type a description. The app estimates fiber in grams, gives the meal a gut score from 0 to 100, explains the score, and offers one concrete suggestion. It tracks fiber, polyphenols, ferments across the day and counts distinct plants toward a 30-plants-per-week goal. All the goals are backed by scientific papers that are linked in a source section within the app
What you can do
- Log a meal by photo, barcode or text and see an explained score, estimated fiber, plant count and a feedback on what you are already doing good and what could improve this meal
- See barcode information for packaged foods, including additives worth noticing. The analysis distinguishes live-culture fermented foods from pasteurized ones and considers ingredients such as omega-3 sources, olive oil and turmeric - you can also use this to compare different alternatives in store.
- Follow daily fiber and weekly plant variety, then look back at your progress. Optional gut check-ins help you notice how you feel alongside what you eat.
- Try weekly challenges, collect stars and build a streak. Protein and calories can appear as estimates, but they don't determine the gut score.
- Use the app without creating an account. Your history stays on your device and in your own iCloud backup. Meal photos are sent for analysis and deleted from the server after the result comes back.
Most food trackers are built around eating less. This one sometimes says the opposite: add beans to lunch, berries to breakfast, or another vegetable to dinner. That is the point of the app, not a loophole in it.
I built the iPhone app in Flutter, with a Go service for meal analysis and RevenueCat for subscriptions. A photo cannot measure a meal like a lab can. The hardest part was making an estimate specific enough to help while being honest about its limits. Feed Your Gut is a wellness tool, not a medical device or medical advice.
What did I do to get my first 100 users
In order to get users I started with tiktok slideshows around the currently viral format of the winter arc. I achieved around 25.000 Impressions within just these 3 weeks, which has then resulted in 454 new customers, with currently 17 active trials and 5 active subscriptions.
The opening figure is rounded from the 2025 Dietary Guidelines Advisory Committee Scientific Report, which found that only 6% of people in the US aged one and up had fiber intakes above the Adequate Intake.
