How it works
Six steps. A rhythm that adapts to real life.
CombiFast is designed so you never open the app and wonder what to do.

Tell us about yourself
A 3-minute conversational assessment: goals, body stats, favorite foods, allergies, cooking time, work schedule, sleep and fasting experience. Includes a wellness screening so recommendations stay appropriate.

Receive your plan
Your CombiFast Plan: a suggested eating window, meal structure, recipe style, approximate daily structure, Morning Reset and the features we recommend for you.

Eat foods you enjoy
Mediterranean principles as the foundation; Italian, Greek, Spanish, Middle Eastern, Mexican, Japanese, Asian and American flavors on the plate.

Fast smarter
A gentle progression — 12:12, 14:10, 16:8 — with an elegant timer, flexible schedules and supportive education. Never extreme.

Adapt every day
Not in the mood for the suggested meal? Tell the Meal Concierge. Swap, regenerate, make it faster, make it Italian, take it to the office.

Track your progress
Weight, measurements, fasting consistency, completed meals, hydration, streaks and weekly check-ins. Consistency is rewarded, not just the scale.
