The hard questions, answered plainly

Three things. Nothing is saved until you have checked it, and the AI cannot change your targets. Foods you confirm, labels you scan and recipes you save are remembered, so repeat meals reuse your own numbers and use no credits. And there are no ads on any tier, with workouts, lab history and export free. What it lacks is listed two answers down; if those gaps matter to you, they matter.

No. There is no import today, so saved foods and streaks from another app do not come across. You can export everything you log here as CSV or JSON at any time. If years of history matter to you, that is a real cost of switching.

Quite a lot. There is no barcode scanner, no meal-photo logging, no searchable food database, no voice button, and no step or calorie-burn sync from a watch. It tracks 11 vitamins and minerals, where specialist nutrient trackers cover many more. It is a web app today, so there are no home-screen widgets and no watch app; the iPhone and Android apps are still being prepared.

In a simpler way. When you have logged at least three weigh-ins in the last seven days, spread over four or more days, the progress check compares your weight trend with the pace your calorie target predicts and moves your calorie target by one 150 kcal step up or down, or leaves it alone. It can change your target at most once every seven days, and never below the app's minimum calorie level (or your estimated maintenance, if that is lower), or more than 25% under your estimated maintenance. It does not model your energy expenditure continuously, and a week of weigh-ins cannot separate fat change from water. Treat it as a nudge, not a measurement.

This is where typing works best. List what went into the pot with amounts, save it as a recipe, and from then on log your share as a fraction, or by weight if you weighed the finished batch. A dish name on its own gets a rough estimate based on typical portions. You know the recipe; the app only has to add it up.

A photo cannot show the oil in the pan, what is under the sauce or how deep the bowl is; typing lets you state those, and you review every number before it is saved. Published tests of general AI chat models on meal photos, which were not tests of calorie apps, found no overall calorie bias, but single meals were often well off and medium and large portions were under-weighed (in one test, 798 g was read as about 530 g). For a plate with several foods a photo is quicker, and photo apps let you correct an estimate too. Speed Macros has not published its own test against weighed food yet, so we do not claim its numbers are closer.

As much or as little as you like. A short entry is filled in with typical portions, and the assumptions it made are listed so you can correct them. More detail, such as amounts, cooking fat or the brand, leaves less to guess. A vague description gets a rough estimate.

Neither is built in. Your phone keyboard's own dictation works in the text box. For packaged food you can photograph the Nutrition Facts panel and check the numbers that were read; that scan uses credits the first time, and afterwards the product is remembered when you mention it. A barcode scanner is quicker for packets, and we do not have one.

Short entries and label scans have taken a few seconds in our own checks so far. Long meals with many ingredients take longer, sometimes tens of seconds, and the app suggests splitting a very long entry in two. Plain foods from the built-in table, and meals you have logged before in the same words, skip the AI step. We have not published a full timing record yet, so we give no headline number.

Yes, and that is deliberate: an estimate can be wrong, and you are the only one who knows what was on the plate. The work shrinks with use. A meal repeated in the same words brings back the numbers you already reviewed, a scanned label is reused when you mention that food again, and a saved recipe logs as a portion, all without credits.

Setup is five short screens: about you, your activity, your goal, food preferences and a review. It asks for a body-fat estimate, which many people have to guess. You accept the Terms and consent to the app storing the health information you enter. Sharing anything with the AI provider is a separate box that is optional and can be changed later in Settings; without it you can still log by hand.

We do not have one yet. No test of this app against weighed meals has been published, so we make no claim about how close its estimates are, and none about being better than any other app. Research on food estimates in general finds that errors are common and that portion size is the biggest cause. Until a weighed-meal test is done, treat every number as an estimate to check.

Five places: a scanned label gives the printed numbers, and foods you confirmed before are reused. A named restaurant or packaged brand is looked up in published restaurant nutrition data held by a third-party source, and a match replaces the estimate for calories, protein, carbs, fat and fiber. Plain foods can come from a built-in table of USDA FoodData Central entries. Everything else, including most home cooking, mixed dishes and independent restaurants, is the AI model's own estimate.

It is the AI model's own rating of how sure it is, shown as high, medium or low. It is not a tested error range, and a high badge does not mean the number is right. Items from a label scan, a restaurant match or the USDA table carry a source badge instead, and the amount you ate is still an estimate unless you stated it.

Less than the calories and macros. Eleven are tracked: potassium, magnesium, sodium, calcium, vitamin D, omega-3, zinc, iron, vitamin B12, vitamin C and choline. For plain foods in the built-in table they come from USDA data, and a scanned label gives only the few it prints; for mixed dishes, and for restaurant and brand matches, they are the AI model's estimate. Entries you type in by hand carry none. Use the totals to notice patterns over weeks, not to judge one day.

More: Micronutrient tracking

Yes. Typing moves the guesswork from a camera to your memory; it does not remove it. Reviews of self-reported eating find that most methods under-report what was eaten. Stating a weight or a measure helps most, and a saved recipe with a weighed batch helps more.

Treat them as prompts to check, not as certification. The app flags estimated items that may conflict with a diet you selected, such as halal, kosher or vegetarian, or with an allergen you listed. It works from the words you type, so it cannot know a restaurant's supplier or a product's full ingredient list, and it can miss things. For any allergy, read the label or ask the kitchen yourself.

Free today, with no ads on any tier: typing in your own numbers by hand, your targets, workouts, bloodwork tracking, progress check-ins, history and export. A short, plain description with amounts, such as "2 eggs and 1 cup cooked rice", can be answered from a built-in table of 271 USDA foods without credits, as can re-logging a meal you confirmed and logging a saved recipe. Anything fried, mixed, vague or from a restaurant goes to the AI and uses credits, and the app does not tell you which it will be before you press Estimate. New accounts get 250 credits, about 8 AI meals, to try the AI features.

Each AI estimate costs money to run. Flat-price apps spread that cost across everyone; this app charges by use, so someone who AI-logs a few meals a week pays a few dollars once, and someone who AI-logs every meal may find a flat unlimited plan cheaper. The downside is real: you watch a balance, and a credit is not a fixed number of meals (a typical AI meal uses about 25, big meals and edits more, label scans about half; meal counts on this site assume about 30). Never metered: logging by hand, repeat meals, saved recipes, workouts, bloodwork tracking and export. Credit packs do not expire.

Plus is priced at $7.99 a month or $49.99 a year for 2,400 credits a month. Every meal count on this site assumes about 30 credits per AI meal, which makes that about 80 meals, fewer if you often edit estimates: two to three AI-logged meals a day and not every meal and snack. Monthly Plus is priced for convenience, not as a discount: per credit it costs the same as the smallest pack and slightly more than the larger packs, and only the yearly plan is clearly cheaper. Unused Plus credits roll over, up to one month's worth.

More: Pricing

Not if you use AI for every meal. The trial includes 500 credits, about 16 AI meals and fewer with edits, which is under one a day across 21 days. It is enough to see how you would use it; heavier use during the trial means adding a pack or falling back to the free ways of logging. Cancelling in Settings before the trial ends means no charge.

Yes. AI requests are limited to 25 a day on every plan, including Plus, and estimates, edits and scans all count. Where the nutrition chat is offered, it has its own separate daily allowance, shown on the chat page. Logging by hand has no limit.

The estimate itself is a call to Anthropic's Claude, and we say so. Around it sits a daily log with totals against your targets, a review step before anything is saved, memory of labels you scanned, saved recipes you log by portion, lookups for named restaurants and plain foods, and export. A chat can keep a running log if you ask it to each time; here you do not have to ask.

No. Targets are calculated by fixed formulas in the app's rules from your age, sex, size, activity and goal. The AI only estimates what is in food you describe, reads labels and lab reports you photograph, and answers questions in the chat where that is offered. It cannot change a target.

Calories start from a standard resting-energy equation (Mifflin-St Jeor, or Katch-McArdle when you enter a body-fat estimate), multiplied by an activity factor and adjusted for your goal. Protein and fat are set per kilogram from sports-nutrition research on people who lift, and carbohydrate is what remains. These are starting estimates: such equations describe averages and can miss one person's real needs by a wide margin.

They are different things. The Daily Values on a label are single reference amounts used for food labelling. Recommended Dietary Allowances are set by the Food and Nutrition Board of the National Academies of Sciences, Engineering, and Medicine, with Health Canada, by age and sex, at a level meant to cover nearly all healthy people. Speed Macros uses those reference intakes for most vitamins and minerals, a standard energy equation with an activity factor for calories, and sports-nutrition research on people who lift for protein. It is general guidance for healthy adults and promises no health outcome.

On the Plan page, "How did we calculate this?" shows, for every target including calories and protein, the formula in plain words, the details of yours that went into it, a link to each source and a grade for how strong the evidence is. Grades are Strong, Moderate or Emerging, and some steps, such as the activity factor, are graded Emerging because they are conventions. Each lab range also names the organisation it comes from. No registered dietitian or doctor has reviewed the rules, and the Plan page says so.

Carbs do not: your carb target is the same every day, and on a day you log a workout the app shows pre- and post-workout timing. Sodium is shown against the same range every day, 1,500 to 2,300 mg, taken from the National Academies' reference intakes. A logged workout does not raise that limit; it only allows for some sodium lost in sweat before the app labels your intake "Too High", and that allowance is the app's own assumption. If you have high blood pressure or kidney disease, or a clinician has given you a number, use theirs.

For a weight-loss plan, the app shows an approximate weekly pace and a time-to-goal figure worked out from your calorie target, using a common rule of thumb for how much energy a kilogram of body weight holds. Both are rough guides: weight often moves in steps, change usually slows over time, and bodies do not follow equations closely. The app promises no result.

There is a maintain goal, and you can ignore the lifting features. But the protein and fat targets come from research on people who lift and are applied to everyone, setup asks for a body-fat estimate, and much of the wording assumes you train. If you only want a rough sense of how you eat, you may not need a tracker at all.

The app estimates 11 vitamins and minerals from what you log, and you can tap any nutrient to see which foods supplied it. It also separates added sugar from natural sugar, tracks saturated fat, counts the variety of plant foods across the week, and flags a day when every protein source shares the same limiting amino acid. All of these are estimates for noticing patterns over weeks. None of them can tell you whether you are short of anything: that takes a clinician and usually a blood test.

More: Micronutrient tracking

It compares one day's estimated intake with a reference amount. It is not a test for deficiency, and one low day means little, because reference intakes describe usual intake over time. A day with missing entries, or entries typed in by hand, reads low too.

That is expected. Few foods contain much vitamin D, and sunlight on the skin is a major source that the app cannot count. The bar shows food, plus any supplement you tick, and nothing else. Only a blood test shows your level.

No. The supplement checklist records the ones you chose at setup so you can tick them off each day, and the app does not tell you to start one. The Plan screen does list a creatine range from sports-nutrition research beside the nutrient targets, and shows upper limits where one exists. Check with a clinician or pharmacist before starting any supplement, especially if you take prescription medication.

No. Accounts are for adults. You are asked for your date of birth at setup and cannot continue if it shows you are under 18, but the app cannot verify it. The targets are not written for people who are still growing.

The targets are not written for you. The app never asks about pregnancy or breastfeeding, so nothing adjusts: nutrient targets stay at the general adult values and a weight-loss goal can still be selected. Please use the numbers your midwife, doctor or dietitian gives you.

The targets are for healthy adults. The app asks nothing about kidney disease, blood pressure, diabetes, an eating disorder or medication, so it cannot adjust for them, and the protein, potassium and sodium targets in particular may be wrong for you. If you take prescription medication, check any change in diet or supplements with your clinician or pharmacist first. Their numbers come before ours.

Only partly. Vitamin and mineral reference amounts change with age, but the calorie deficit, the protein rules and the weight-loss rate are not adjusted for people over 65. Losing weight and protein needs at that age are worth discussing with a clinician before following an app's numbers.

For some people, yes. Counting calories can feed unhealthy patterns, especially for anyone with a history of disordered eating, and this app shows deficits, targets and badges every day. Calorie targets are not set below 1,200 kcal a day for women or 1,500 for men (or below estimated maintenance when that is lower), and the progress check can change your target at most once every seven days, by one 150 kcal step; those figures are the low end of the usual prescription ranges in a 2013 US obesity guideline, not a proven threshold for any one person. There are still no screening questions at setup. If tracking makes you anxious about food, please stop, and talk to a doctor or an eating-disorder helpline in your country; in the United States, the National Institute of Mental Health lists where to find help, and you can call or text 988 in a crisis.

It keeps your lab results in one place so you can see how they change between tests. For 11 common markers it shows where a value sits against a general reference range the app applies, names where that range comes from, labels a value outside the range as outside it, and asks you to review those with your clinician. A value well outside the usual range shows a line telling you to contact your clinician. Everything else on your report is copied as printed, with your lab's own range.

More: Bloodwork tracker

No, on purpose. It does not suggest foods, supplements or doses from a lab result, and it does not say what a result means for your health. Its job is to give you a clear history to take to your doctor. Your lab's own range and your clinician's advice come first.

Several. One general range per marker is applied to everyone, whatever your age, sex, medication or your lab's method, so your lab's own range and flags come first. Results in common international units are converted and both numbers are shown; a unit the app does not recognise is marked "Not rated" and gets no label at all. Anything outside the reference range, on either side, carries a note to review it with your clinician, and a value well outside the usual range says to contact your clinician; neither names a condition or says what the result means for you.

Your records sit in your own account, and each signed-in session can read only its own rows. There are no ads, no ad trackers and no third-party analytics, and your information is not sold. The service is run by one person, who can access account data for support and operations when needed. You can export or delete everything yourself.

Not unless you choose it. AI sharing is a separate, optional box at setup that you can switch off later, and only a request you make with it on, such as a meal description, a label photo or a lab report, is sent to Anthropic to be processed. Its commercial terms do not allow it to train its models on that data, and it states that it deletes API inputs and outputs within 30 days, with limited exceptions. Speed Macros does not keep the photos or PDFs. Entering values by hand sends nothing to the AI.

No. The rules were put together by the developer from published guidelines and research, and no registered dietitian or doctor has reviewed them, or the answers on this page. That is why the app describes its output as general guidance for healthy adults and not as medical advice.

You can export your records as CSV or JSON from Plan at any time, which needs no trust in anyone. The Terms say that if the service is discontinued, prepaid Plus fees for the unused period and unused purchased pack credits are refunded; that promise is made by one individual, not by a company with reserves. There is no formal continuity plan to point to, and the AI features depend on outside providers.
