# CaloMatic

> CaloMatic is an AI calorie tracker for iPhone that logs a meal from one photo, using LiDAR depth on Pro iPhones to measure portions, and sets an adaptive calorie target with a coach that runs on your iPhone.

- There is a waitlist at https://calomatic.app/#waitlist. People who join hear the launch price before anyone else.
- There is no App Store listing, price or release date yet.
- CaloMatic is not a medical tool.
- The reviews section on the website shows reviews from closed beta testers, written before launch.

## Who it is for

Adults who train and want to lose fat or hold their weight, with a target that adapts to them.

## Photo scan: one photo becomes a 3D model of your meal

1. **Take one photo.** Hold your iPhone over the plate. One shot, no walking around it.
2. **LiDAR reads the height.** Depth arrives with the photo, so a tall serving counts for more than a flat one.
3. **AI separates the foods.** Each food becomes its own shape with its own name.
4. **Portions turn into grams.** Confirm it and the whole meal is in your diary.

Pro iPhones measure the real depth of the plate with LiDAR, so portions come from the size of the food, not just how it looks. On every other iPhone the camera finds the table and sizes the meal from there. You see every food and portion, and you can fine-tune anything before it is logged.

## Four ways to log a meal, one diary

- **Barcode:** Point at the barcode. The food, its nutrients and its share of your day appear before you press Add.
- **Nutrition label:** Scan the nutrition label on any package, even one no database has heard of.
- **Search:** Search 3 million foods. Your own foods come first, so the things you eat every week take two taps.
- **Photo:** Snap the plate. CaloMatic builds the plate in 3D, works out every food and shows you how. One confirm and it is logged.

## Food diary

- Every meal sits at the hour you ate it, and the day adds up as it goes: calories against your target, plus protein, carbs and fat.
- Expenditure trend: what you really burn, tracked day by day.
- Habits: every weigh-in and logged day, thirty days at a glance.

## Adaptive coach: an adaptive coach built on a live model of your body

Every weigh-in and meal updates the model. It tells water from real change, learns what you actually burn, and uses AI trained on 2 million simulated bodies to set your calorie target.

One number on the scale has four things behind it, and CaloMatic separates them every day, so a salty dinner counts as water, not fat:

- Real weight (body tissue)
- Water from carbs
- Undigested food
- Day-to-day water

It also learns your daily burn from your own numbers. It gets sharper with every week you log, and if you always forget the cooking oil, it learns that too.

How a target is set ("The maths proposes. You decide."):

1. **Your log:** your weigh-ins and meals, exactly as you log them.
2. **Body model:** six hidden signals, updated every day. Odd weigh-ins count for less.
3. **Neural network:** runs on your iPhone and fine-tunes your target.
4. **Noise check:** changes too small to matter are skipped.
5. **Weekly check-in:** your target moves only when you accept.

### Simulation results

The coach was trained on 2 million simulated bodies and tested on 1.8 million new ones. CaloMatic and a standard adaptive coach were run on the same simulated dieters, and each was measured on how close it got to every person's ideal daily calorie target. "Closer" means a smaller average gap between the set and the ideal daily target.

- 45% closer to the ideal target than a standard coach
- 1.8 million simulated people
- 10 of 10 scenarios won

How much of the standard coach's gap CaloMatic closes, by type of dieter:

| Type of dieter | Closer to target |
| --- | --- |
| Messy real life, with steps | 40% |
| Messy real life | 37% |
| Metabolism that fights back | 39% |
| Sloppy weigh-ins and logging | 51% |
| Perfect logging | 50% |
| Different body types | 40% |
| Routines that keep changing | 33% |
| Typical person | 45% |
| Textbook weight loss | 35% |
| Steady metabolism | 47% |

These results come from simulated people, not a clinical trial.

## Frequently asked questions

**Do I need an iPhone with LiDAR?**
No. Pro iPhones add LiDAR depth, and on every other iPhone the camera finds the table and sizes your meal from there.

**How does the photo scan work out portions?**
Pro iPhones measure the real depth of your plate, so portions come from the size of your food, not just how it looks. You see every food and portion, and you can fine-tune anything before it is logged.

**Who is CaloMatic for?**
Adults who train and want to lose fat or hold their weight, with a target that adapts to them.

**Does it work offline?**
Yes. Your diary and manual logging work anywhere. Photo scans use a connection, and your photos go to AI only when you say so.

**Can I take my data with me?**
Always. Export your diary or delete your account from the app, any time.

**What will it cost?**
Join the waitlist and you will hear the launch price before anyone else.
