f*rk is a plant-diversity tracker built around one simple gut-health target: thirty different plants every week. Log meals by text, voice, photo or barcode and f*rk counts the distinct fruit, vegetables, nuts, seeds, legumes, whole grains and herbs you ate — not just the calories. Alongside plant diversity it tracks fermented foods and polyphenol-rich ingredients, so you can see the whole picture of how varied your week really was.
Weekly quests, badges and head-to-head challenges keep it playful: pick fruit, vegetables, fermented foods or everything, invite a friend or your family, and compare who brought the most variety to the table. Families can add child accounts, teachers can run a class, and everyone keeps their history across devices.
