What it does

Everything you need for a hard week, nothing you don't.

Challenges with friends

Thirty days of walking, a 16-week weight-loss push, a fasting reset — solo or with a group, a leaderboard and a streak to protect.

Log food in seconds

Scan a barcode, snap a label, or search 400,000+ products with real serving sizes. Drinks count toward your water. No spreadsheets.

A program that fits your gym

A six-week lifting plan with rest timers, last time / best for every lift, and swaps that stay in the same muscle group when the machine you need is taken.

Your health data, one screen

Steps, sleep, weight, heart rate and more from Health Connect or Apple Health — shown, never sold. Workouts and water you log go back to your health app.

A coach that reads the room

A short daily note built from what you actually logged — calories left, steps to go, how your weight is trending — timed to your day, not a generic push.

Progress you can see

Weigh-ins with a trend line that only speaks when it has enough data, sessions compared to last time, and a week that fills in as you go.

How it works

Three things a day. That's the whole idea.

Pick a challenge

Start with a 30-day walk or go straight to the 16-week TRIM 1. Invite friends or go solo.

Log what you did

Food, water, a weigh-in, a workout. Most of it takes one tap; the rest comes from your health app.

Let the week add up

Streaks, a group leaderboard and a coach that tells you what's next — not what you did wrong.

Start your first challenge this week.

TRIM is free to start. Plus and Premium add more programs, custom group challenges and the deeper coaching.
