Support

SmartCrunch is made by one person. There is no ticket system and no chatbot — email arrives with the developer, and that is the whole support channel.

Typical reply

Within a few days. There is no guaranteed response time.

Language

English or Russian.

You can write from inside the app as well — Settings has a support row that opens a pre-filled message. Please keep whatever it fills in: it says which build you are on, which saves a round trip.

Requirements #

• An iPhone running iOS 26.0 or later. Nothing older is supported.
• A network connection for barcode lookups, product search and — on Pro — the AI. The diary, the budget and everything computed from them work offline; only lookups need the network.
• A camera, if you want to scan barcodes or photograph meals.
• Apple Health is optional. The app is fully usable with it switched off.
• There is no iPad, Mac, Apple Watch or Android version, and none is in progress.

What the app does #

One thing: it steers what you eat towards a goal weight. It gives you a daily calorie and macro budget, a diary to spend it against, a weight trend, and an estimate of how far away the goal is at your current pace.

There is no tab bar and no navigation stack. One permanent screen shows the day — remaining calories, three macro bars, what you have eaten, and the weight line — and everything else opens as a sheet over it, one at a time. That is a deliberate design, not a missing feature.

What it is not: a training app, a coach, a social network, or a medical tool.

Where the food data comes from #

Barcode lookups and product search both query Open Food Facts, an open, community-maintained food database. SmartCrunch is not affiliated with it.

• Records are contributed by the public, so they can be incomplete, out of date or simply wrong — particularly for regional products and store brands.
• When a record is missing a macro, the app says so instead of substituting a zero. A missing figure treated as zero is what makes a day of packaged food look immaculate, which is exactly backwards.
• If a product cannot be found, enter it by hand. Manual entry is always available and is never behind the paywall.
• Corrections to a product record belong upstream, at Open Food Facts — fixing it there fixes it for everyone, including you on your next scan.

Apple Health #

Health is optional and off until you grant it. iOS asks per data type, and you can revoke any of them at any time in Settings → Health → Data Access & Devices. Revoking does not delete anything already in your diary.

What the app reads and uses:

• Energy: active and resting energy burned, and dietary energy consumed.
• Body mass and body fat percentage — the weight trend and its forecast.
• Height, read once, for the baseline estimate.
• Dietary protein, carbohydrate, fat and water.
• Date of birth and biological sex, read once, for the same baseline estimate.

What the app writes — exactly four things: the day's total dietary energy, protein, carbohydrate and fat. Nothing else is ever written back. Water is deliberately excluded: the day's water figure is a number you type, not one the app computes, and pushing a manual value back into Health would be exporting your own input as if it were a measurement.

Samples the app itself wrote are filtered out when reading, so a figure can never be counted twice. The complete list of Health types the app requests permission for is in the Privacy Policy.

No account, and where your data lives #

• There is no sign-up, no login, no password and no profile on a server.
• There is no feed, no sharing, no friends and no leaderboard.
• Your diary, weights and goals live in the app's own database on your iPhone. They are included in an encrypted iPhone backup, and restoring that backup restores them.
• Because there is no account, the diary does not follow you to a new phone except through a device backup, and there is nobody who can recover it for you if it is lost.
• Two things do leave the phone, and both are opt-in and separately switchable in Settings → Privacy: the AI (only when you use it — see below), and pseudonymous product analytics and crash reports. Decline either and the app works exactly as before, minus that feature. The Privacy Policy sets out what each one sends.

How the AI works — and what it does not do #

The AI is the entire SmartCrunch Pro feature set, and it does one kind of job: it guesses what a meal was.

• Photograph a plate, or write “bowl of ramen and a beer”, and it proposes a dish with its macros. The proposal opens as an editable draft — you correct it before anything is saved.
• Ask it for a plan and it suggests meals that fit whatever is left of today's budget.

The AI never computes a number you rely on. Your budget, your macros, your energy balance, your weight trend, your maintenance estimate and your forecast date are all computed by the app's own engines, on your phone, from your entries. The model's output is an input to the diary — a suggestion about what a food was — and nothing more. This is a structural rule in the codebase, not a policy.

How the request travels: the photo or sentence goes to a small relay service operated by the developer, which forwards it to Google's Gemini model and returns the answer. The relay exists so that no API key ships inside the app. It is not used to build a profile of you, and the app has nothing to attach a profile to — there is no account.

Fair-use limits apply to AI requests per day. They are set well above normal use; if you hit one, the app tells you which limit and when it resets. Everything else in the app keeps working.

An estimate from a photo is a guess about a photograph. Treat it as a starting point, and correct it — that is what the editable draft is for.

Subscription, billing and cancelling #

SmartCrunch Pro is an auto-renewable subscription sold through the App Store. Apple handles the payment, the renewal and the receipt; the developer never sees your payment details.

Prices are the configured US storefront prices; your own currency and price appear in the App Store at the point of purchase. There is no free trial and no introductory offer. Billing starts on day one.

To cancel: Settings → your name → Subscriptions → SmartCrunch → Cancel Subscription. The app also links straight to that screen. Cancelling stops the next renewal and leaves Pro working until the period you have paid for ends; every free feature carries on regardless.

Refunds are handled by Apple, not by the developer — reportaproblem.apple.com. If something in the app is at fault, write to [email protected] as well, so it gets fixed.

Bought Pro and it has not appeared? Settings has a "Restore purchases" row. If that does not resolve it, email [email protected].

Languages #

The interface is translated into 23 languages: English, Русский, Français, Deutsch, Ελληνικά, Español, 日本語, 한국어, 繁體中文, Polski, Čeština, Português, 简体中文, Italiano, Türkçe, Português (Brasil), العربية, עברית, Svenska, Dansk, Norsk bokmål, Suomi, Nederlands. It follows your iPhone's language, and you can override it per-app in the app's own settings.

Food names come from Open Food Facts and appear in whatever language the contributor entered them, which will not always match your interface language.

Deleting your data #

• One entry: tap it in the day's list and delete it.
• Everything: delete the app. Because there is no account and no server-side copy of your diary, removing the app removes the data with it. Check your device backups too, if you want it gone from those.
• What the app wrote to Apple Health is not the app's to delete on your behalf. Remove it in Health → Browse → Nutrition, or through Health → Data Access & Devices → SmartCrunch → Delete All Data.
• For any request about data held outside your phone, write to [email protected]; the Privacy Policy sets out your rights formally.

Known limitations #

Stated plainly, because finding them out one by one is worse:

• The learned maintenance figure needs weeks, not days. It is computed from your logged intake against your measured weight trend, so it needs a run of days that were actually logged and a run of weigh-ins long enough for a trend to exist. Until then the app says so and uses a conventional estimate instead.
• It is only as honest as the diary. Systematically logging less than you eat drags the learned figure down with it. The app applies several checks and refuses rather than publish a number it does not trust, but no check can see the meal you never entered.
• Micronutrient figures depend on the database. Fibre, sugars, sodium and saturated fat are only as complete as the product records, so the app shows coverage — how many of the day's entries the number was computed from — beside the number.
• Body-weight arithmetic is a model. Everything about pace and arrival dates rests on a standard energy-per-kilogram constant. Real bodies vary, water shifts by a kilogram day to day, and the forecast moves when the data moves.
• No saved meals or recipes. You can repeat yesterday's meal in one tap and pick from recent and frequent items, but there is no way to save a named combination yet.
• No iPad, Mac, Watch or web version, and no widgets.

Reporting a bug #

Email [email protected]. What makes a report immediately actionable:

• What you did, what you expected, and what happened instead.
• The app version and build (Settings → About), and your iOS version.
• A screenshot, if the problem is something you can see.
• For a wrong number: the day it is on and the entries that make it up. A figure being wrong is usually traceable to one entry.

Please do not include anything you would not want in an ordinary email. A screenshot of the diary is plenty; medical records are never needed.
