Your all-in-one app for diet, body composition and workouts
Real Research,
Real Data,
Real Results
What you eat, how you train and how your body changes, in one place and working toward the goal you set. BodyComp keeps what was measured apart from what was estimated.
- ResearchTargets and guidance cite published studies.
- DataFrom your scale, DEXA scans, food log and wearable.
- ResultsYour own measured pace, shown beside the plan's projection.
Screens show sample data.
What it does
Log a meal in seconds
Search, scan a barcode, photograph a plate or say what you ate. Every food the AI reads is a draft you confirm before it is saved.
Burn from your wearable
Read from Apple Health or the wearable you connect. A day with no burn figure says which day and why.
Targets that move with you
A plan built from your goal, carb cycling if you want it, and a weekly review of what you logged.
Every set and every rest
Routines, a live workout with rest timers, and progress for every exercise.
Scan, scale and trend apart
Import a DEXA report. Scans and scale readings stay distinct on one chart.
See them side by side
Every metric over a week, a month or 6 months.
Macros against your body
Put weight, body fat, lean mass or fat mass over any diet chart. One drag reads both.
Sets by muscle
A row for every muscle you trained, a column per day or per week, shaded by direct sets. A week you didn't train stays on the grid, drawn faint.
Train together
Rooms for your training partners or your coach: messages, photos, replies and reactions.
- Share a recipe. It arrives as a card: open it to see the ingredients and macros per serving, and Save puts a copy in their recipes, theirs to edit.
- Report or block anyone, in any room. Reported chat is reviewed by a person.
- Chat is optional and asks for your agreement before your first room. What you post there is stored on our server so the people in the room can see it; your food log, workouts and body data never are.
Why BodyComp asks for health data
What it reads, and why
Burn, sleep, workouts and body measurements come from Apple Health or the wearable you connect, read-only. They power your energy balance, targets and weekly review.
Your log stays on your phone and in your own iCloud. Health data is never sold and never used for ads. BodyComp never sends your progress photos anywhere.
What leaves your phone
When you start an AI feature, that request goes through our server to Anthropic, and our server keeps no copy of it, only which feature and model ran, how many tokens it used and what it cost. The weekly review sends the most: a week of daily food totals, workouts, sleep, burn, your weight trend, latest DEXA scan, targets and goal.
Food searches and barcodes go to public nutrition databases. If you sign in, our server also keeps an account record with your consent choices and any purchase, the tokens for a wearable you connect, which wearable you use, your chat name, your handle and picture if you set them, and anything you post in a chat room.
Where your numbers come from
Every connection is optional and read-only, and each has a page saying exactly what is read and how to remove it.
