SlimmerYou is an intermittent fasting app you do together. Join a fasting circle, chat with members in real time, and share photos of what you break your fast with, while live reminders and a stage chart keep you on track.

TRACK YOUR FAST
Pick from beginner-friendly windows like 12:12 and 14:10, popular patterns like 16:8, or advanced and extended fasts up to 72 hours. A live timer and visual stage chart show exactly what's happening in your body as the hours pass, from digestion through fat-burning and into autophagy.

STAY ON TRACK WITH REMINDERS
SlimmerYou nudges you along the way: an hourly reminder to drink a glass of water, a heads-up 30 minutes before your fast ends so you can prepare something gentle like broth, and an alert the moment your fast is complete.

FAST WITH FRIENDS
Join a public fasting circle built around your protocol — 16:8, OMAD, Beginner 12:12, 5:2, Autophagy, or Menopause & Hormonal Fasting — or create your own private circle with an invite code. See who's currently fasting, how long they've gone, and send a quick cheer to keep each other motivated. Browse every fasting style in one place under Fast Types, and jump straight into its circle. Premium members can also chat with their circle in real time and share what they're breaking their fast with.

GET A PERSONALIZED PLAN (PREMIUM)
Tell SlimmerYou your goal, experience level, and a few basics, and Premium unlocks a week-by-week fasting plan built around your BMI and goal — paired with diet guidance and exercise tips matched to your experience level. Print or share it any time.

TRACK YOUR PROGRESS
Log your weight and body measurements monthly to see real change beyond the scale. View your fasting stats, streaks, and unlock achievements as you build consistency.

LEARN AS YOU GO
The Learn tab breaks down what's happening at each stage of a fast, compares different fasting protocols, and covers practical nutrition guidance: what's okay to have during a fast, how to break a fast safely, electrolyte tips, getting adequate rest, and eating a balanced diet during your eating window.

SlimmerYou is built for general wellness tracking, not as a medical device. Always talk to a doctor before starting a fasting routine, especially for extended fasts or if you have any health conditions.
