Calorie tracking for iPhone
One number, every day:
how much you can still eat.
SmartCrunch does one thing — it steers what you eat towards a goal weight. No training plans, no feed, no account. A ring, a diary and a weight line, on one screen.
SmartCrunch is not on the App Store yet. It is being prepared for release, so there is nothing to download today. This page exists so you can see exactly what the app does — and does not do — before it ships.

The difference
The budget learns you, instead of assuming you.
Almost every tracker asks your height, weight, age and sex, runs a formula and calls the answer your maintenance. Two people with identical answers get identical numbers — and can be hundreds of calories apart.
The usual way
A formula about a population
Height, weight, age, sex, an activity multiplier — done in the first minute, before the app has seen you eat anything. It never updates itself, because nothing in it is measured.
maintenance = BMR × activity guess
What SmartCrunch does
Arithmetic on your own weeks
Once you have a few weeks of entries and weigh-ins, the app solves the energy balance backwards: what you ate, against where your weight actually went. That figure absorbs the things a formula cannot know — metabolic adaptation, and the fact that you under-count your portions by a tenth.
maintenance = average intake − (weight trend, kg/day × 7700)
A goal weight, in plain terms
How much is left, how far along you are, and the date you arrive at the current pace. Change the pace and the date moves with it — the budget and the forecast are the same calculation, so they cannot disagree.
A trend line, not a verdict
Weight is drawn as a seven-day moving average through your measurements, so a heavy morning is one dot and not a judgement. Weigh in from Apple Health or type it — both feed the same line.
Getting food in
Four ways to log a meal. None of them costs money.
Logging is the whole job, so it opens from the one button on the canvas and finishes inside a single sheet — the steps change in place instead of stacking new screens on top of each other.
Scan a barcode Free
Point the camera at the packet. The product comes back from Open Food Facts, the open food database. If some macro is missing from the record, the app says so on the spot rather than filling the gap with a zero.
Search the same database Free
Type a name and pick from the results. Recent and frequent items sit under the search field, because the food you log today is usually food you logged last week.
Repeat yesterday Free
One tap copies yesterday’s breakfast, lunch or dinner into today, with the total shown before you tap. No confirmation dialog: every line can be deleted again.
Type it in Free
Name, portion, calories, protein, carbs, fat. The manual route is always there and never behind a paywall — it is what makes the app usable for a food no database has.
Beyond calories
Every scanned product brings more than calories.
Fibre, sugars, sodium and saturated fat come with the products you scan or pick out of the food database, and their targets are derived from your own budget rather than from a generic adult — a bigger budget moves them, a smaller one moves them back. A meal you type in yourself, or one the AI estimates from a photo or a sentence, carries no such figures: the app leaves them unknown rather than counting them as zero.
The striped bar is the honest case: some of today’s entries carry no sodium figure at all — a product record with the field missing, or a meal that was typed in rather than scanned — so the app reports it as unknown instead of counting it as zero, and shows you how many of the day’s entries the number was actually computed from.
Unknown is a value
A missing figure — in a food record, or in an entry that never had one to begin with — is not a zero. Treating it as one makes a day of packaged food look spotless, which is exactly backwards. SmartCrunch shows coverage — how much of the day the number covers — next to the number.
Apple Health, both ways
Reads energy, body mass and body composition, height and dietary entries. Writes exactly four daily totals back: energy, protein, carbohydrate and fat. Nothing else is written, and nothing at all is required — the app works with Health switched off.
Pricing
Free where it counts. Pro is only the AI.
Free, with no daily limits
- The calorie budget and the full food diary
- Barcode scanner and product search
- Fibre, sugars, sodium and saturated fat, from the food database
- Goal weight, trend line and forecast date
- Apple Health sync, in both directions
- Your whole history, on your device
SmartCrunch Pro Subscription
- Estimate a meal from a photo, and correct it before saving
- Estimate a meal from a sentence, the same way
- A suggested plan for the rest of today’s budget
That is the entire difference. Pro adds no number and changes no calculation — the AI proposes what a meal was, and the app’s own engines do the arithmetic, exactly as they do on the free tier.
Prices are the configured US storefront prices and are shown for orientation; your local price and currency appear in the App Store at purchase. There is no free trial and no introductory offer — billing starts on day one and renews until you cancel it in your Apple ID subscription settings. Cancelling stops the next renewal; the free features carry on working either way.
Questions
Before you ask.
Is there a free trial?
No. There is no trial and no introductory price — SmartCrunch Pro bills from day one, and you cancel in the App Store whenever you like. Everything listed as free is free forever, with no daily caps, so you can decide whether the app suits you without paying anything.
Do I need an account?
No. There is no sign-up, no login, no social feed and no leaderboard. Your diary lives on your iPhone.
What does Pro actually add?
One thing: the AI. A photo or a sentence turned into a first estimate of a meal, and a suggested plan for the rest of the day’s budget. Nothing in Pro changes a computed number — the app’s own engines do all of the arithmetic either way.
What if I log badly for a week?
Then the app does not pretend. The learned maintenance figure requires a run of days that are actually logged, and if that run is not there, it says so and falls back to a conventional estimate instead of quietly printing a number it cannot support.
Does it work with Apple Health?
Yes, in both directions. Weight and energy can come in from Health, and the day’s four totals — energy, protein, carbs and fat — are written back. You can also just type your weight in; Health is optional.
Which iPhones does it run on?
Any iPhone on iOS 26.0 or later.
