Question 1

What is Feel Index?

Accepted Answer

Feel Index is a free AI-powered health tracking app for iOS. It connects your food, workouts, medications, supplements, and mood to a single daily Feel Score. An AI health coach then explains why you feel the way you do and answers your questions. Unlike MyFitnessPal or Cal AI, Feel Index shows you how your choices affect how you feel — not just what you ate.

Question 2

What is the Dietary Inflammation Index and how does Feel Index use it?

Accepted Answer

The Dietary Inflammation Index (DII) is a validated scientific score that measures how pro-inflammatory or anti-inflammatory your diet is. Feel Index automatically calculates your DII from the foods you log and connects it to your daily Feel Score, so you can see exactly how your diet is affecting your energy, mood, and wellbeing.

Question 3

How is Feel Index different from MyFitnessPal or Cal AI?

Accepted Answer

MyFitnessPal and Cal AI tell you what you ate. Feel Index tells you how it made you feel. In addition to food and macro tracking, Feel Index tracks medications, supplements, symptoms, mood, fasts, and workouts — then an AI coach connects all of it to your daily Feel Score and explains the patterns. The Dietary Inflammation Index is a feature no other mainstream app offers.

Is Feel Index free to download?

Yes. Feel Index is free to download on iOS with a 7-day free trial of all premium features. The free tier includes food logging, medication tracking, and Apple Health sync. Premium unlocks AI coaching, advanced analytics, and personalized insights for $4.99 per month or $39.99 per year.

Question 5

Can Feel Index track medications, supplements, and symptoms?
