Belly is built on one idea: a short flow you actually do every day beats a
punishing program you quit in week two. The 66 isn't a marketing number —
research on habit formation found a median of 66 days for a behaviour to
become automatic. It's a length, not a test of endurance.
THE DAILY FLOW
• About 35 minutes, laid out move by move
• Video for every move, so you're never guessing at the form
• Cast the flow to your TV over AirPlay
• Day 1 through day 66 is already planned — nothing to build, nothing to configure
YOUR MEALS, PHOTOGRAPHED
• Take a picture, or pick one from your gallery
• No weighing, no scrolling a database, no barcodes
• Your day becomes a visual record you can actually look back on
• Every photo lands in your history, in order, by day
TARGETS THAT COME FROM YOUR OWN NUMBERS
Your calorie and macro targets are calculated from your age, height, weight,
goal and how much you really move during an ordinary day — not pulled off a chart.
• Mifflin-St Jeor with an activity multiplier
• Any deficit is capped, with a hard floor underneath it
• Maintaining instead of losing? Then no deficit at all
• We show you roughly how long your goal takes, without promising what we can't
WITH A FRIEND, IF YOU WANT ONE
Start a small circle, send an invite code, and go through the 66 days alongside
people you actually know. Or skip it entirely — the app works exactly the same
on your own.
ONE REMINDER, IF YOU WANT IT
A single nudge a day, at a time you choose. Off unless you turn it on.
YOURS ON EVERY DEVICE
Sign in with Apple or Google and your days, your photos and your targets follow
you to a new phone.
WHAT BELLY DOESN'T DO
No food scores. No lecture when you eat something you enjoyed. No
before-and-after gallery. No leaderboard full of strangers.
Start with day 1.
