Zero cooking or thinking required
FastMacros reads what's left in your day and finds real orders from menus near you that fit — protein-first, within your calories. You tap once; we do the thinking.
Coming soon to the App Store and Google Play
The loop
The whole app is one loop. It runs on your real remaining macros, not a food diary you have to babysit.
We pull what you've eaten and burned from Apple Health or Health Connect and show what's left today.
Our solver ranks combinations from nearby menus by how well they fit your remaining macros — protein weighted highest.
Pick a winner and we hand you off to the restaurant's own site or your delivery app, with the exact order kept on screen to re-enter.
Confirm you placed it and the meal logs straight back into your day — the loop closes on its own.
What's inside
Honest tools, built around the way you actually eat.
Read weight, nutrition and active energy from Apple Health and Android Health Connect, then see exactly what's left — calories, protein, carbs, fat. It goes both ways: turn write-back on and the meals and water you log here mirror into your health store too.
We rank real orders from menus near you that fit your macros, honor your diet and allergen filters, and stay in your calories. No searching, no math.
Hand off to the restaurant's own ordering site first, or your delivery app. We can't pre-fill their cart, so we keep the exact order — every item and modifier — in large selectable text while you re-enter it. You place it; the meal logs back to your day.
Plan a whole day around your eating window, or build a week of recipes into one aisle-grouped shopping list you can send to your grocery cart.
Log by photo, a plain sentence, a barcode, or a nutrition label. A row is tagged “Verified” when its numbers come from the USDA database we ingest and check, and names its source outright wherever we have one to name — and where we can’t, you get no badge rather than an implied one. Prices and allergen data we haven’t verified carry an “est.” tag — never a guess dressed up as a fact. Underneath, 23 micronutrients — vitamins, minerals and fiber — plus caffeine, alcohol and the fat subtypes add up from whatever your foods actually reported, and only from that. A nutrient nobody measured stays blank, not zero.
Mac reacts to what you actually log — steady, on your side, and designed never to shame you. Pick the look you like; every coach is named Mac.
Where we've gathered prices in your area you see the real “price on DoorDash”; everywhere else it's clearly shown as an estimate.
A gentle streak, adaptive targets that learn from your real intake, and progress you can actually read — no punishment, no fake pressure.
Optional modes reshape suggestions for smaller appetites or a sodium cap. Nutrition assistance only — never dosing or medical advice.
Ways to use it
FastMacros bends around how you actually eat — not the other way around. A few of the people it's built for:
Set the goal dial and every suggestion re-solves around it — a cut trims calories but never your protein, a bulk raises both on purpose. Adaptive targets then learn from your real weigh-ins and intake, so the plan follows your body, not a formula.
Long day, zero decisions left. Open the app and the ranked order feed is already there — the best-fitting real orders within your remaining macros, from places actually near you, ready to place. Dinner solved in under a minute.
Fill a week from 2,000 original recipes (or auto-fill it to your macros), get ONE aisle-grouped shopping list with everything consolidated, send it to your grocery cart, and follow step-by-step cook mode with built-in timers.
Tell it your eating window and it plans meals inside it, counts down to your next window, and grades a declared fast day as on-protocol instead of scolding you for “under-eating.” Optional reminders can say when the window opens and before it closes — never after — and quiet hours hold back anything the app chose the timing for. The stages it explains cite their research; there's no “autophagy unlocked” badge, because no human study pins that to an hour.
A smaller-appetite mode right-sizes suggestions, daily check-ins track appetite and comfort on your device, and a one-tap PDF summarizes your record for your clinician. When you come off, a “coming off” setting you turn on yourself eases the smaller-meal cap back over a few weeks instead of leaving it stuck there — we never infer it from your data. The whole companion is free. Nutrition assistance only — never dosing or medical advice.
Set your allergens once and anything we know carries what you avoid is filtered out. Where nobody publishes an item’s allergens we don’t guess and we don’t quietly drop it either — it stays visible, marked as unchecked, and it is never auto-selected for you. Nothing is ever marked “safe”; allergen information is an estimate carrying a cross-contact warning. Always confirm with the restaurant.
Household mode solves one order across everyone's targets — one cart, one delivery fee, each item tagged for its person — and the weekly planner scales batch cooking to feed the family.
Type them in, paste a link, or photograph a handwritten card — your recipes live in your private box, scale to any serving count, and rank right alongside everything else when they fit your day.
Publish a recipe or a whole week as a program, and — if you turn your profile public — your name and picture ride along with it. Your profile keeps a record of what you've actually contributed: recipes published, weeks other people applied, menu data you helped confirm. No zero-brags — a tally appears only once it's real — and the milestones count what you gave, never how popular it turned out to be. Never your weight, and never what you ate.
Meet Mac
Mac speaks up when you log a meal, close a gap, or hit your numbers — with deterministic, on-brand lines, not a chatbot guessing at your health. Every word is swept so it recognises your food and your effort, never your body.
Prefer a different look or a calmer voice? Pick from several coach looks and personalities. They're all named Mac.
The honest app
Nutrition apps are easy to fudge. We'd rather show you less than show you something wrong.
If we don't have a number, we leave it blank. We never fill a gap with a guess.
A food row says where its numbers came from — tagged “Verified” for the USDA database we ingest and check, or naming the manufacturer’s label, the community catalog, or the restaurant that published them. That tag is about the calories and macros only; it is never a statement about allergens. Where we can’t name a source you get no badge rather than an implied one; prices and allergen data we haven’t verified carry an “est.” tag; and a number we simply don’t have is left blank rather than guessed.
Anything we know contains what you avoid is filtered out. Where nobody publishes an item’s allergens we say so on the card and never auto-pick it for you. Nothing is ever marked “safe” — allergen information is an estimate with a cross-contact warning.
FastMacros is nutrition information, not medical advice. Our tools help you hit targets; they never give dosing or clinical guidance.
For those who serve
Verified law enforcement, firefighters, EMS, active-duty military and veterans get half off Plus and Pro. Verification at launch through a trusted ID service (like ID.me or SheerID) — a quick one-time check, and we never see your documents.
Almost here
FastMacros is in the final stretch before launch. It's coming soon to the App Store and Google Play.
