A plan based on your metabolism — everything that makes it work
MacroPair starts with a formula the way every tracker does, then leaves formulas behind — measuring your actual energy expenditure from what you log and weigh, week after week. Below is the core toolkit — the full list lives on the roadmap.
The adaptive engine
Weekly target adjustments
Intake in kcal versus weight trend, re-estimated on a rolling window — targets shift by a bounded, safe amount and never lurch.
Adjustment receipts
Every change comes with a plain-language explanation of what moved and why — no black box.
Trend weight
Daily weigh-ins in lb or kg are smoothed into a trend line that ignores water-weight noise and respects real change.
Interactive goal field
Drag your goal weight and date directly on the graph — the forecast cone, safe-pace band and intake floor answer in real time.
Day flags
Rest, travel, sick — one tap tells the engine how to weigh the day instead of letting an off-day distort the week.
Training-aware targets
Lifting and cardio days carry their own session energy in kcal, so training days feed you and rest days don't overshoot.
Macros you control
Drag the split to set protein, carbs and fat — or pin carbs and let fat absorb the rest. Sensible floors in g throughout.
Protein guidance
Protein targets scale with your body data and goal, with evidence markers shown right on the macro bar.
Maintenance mode
Holding steady is a goal too — a maintenance band with gentle nudges when the trend drifts out of it.
Every fast path into the diary
Barcode scanner
Point, beep, logged — against a catalog of 500,000+ foods from USDA and Open Food Facts, refreshed monthly.
Nutrition-label reader
Photograph any label and it becomes a food — with serving sizes sanity-checked against plausibility rules before you can log them.
Photo estimate
Snap a plate and get a macro estimate you can review and adjust before it lands in your diary.
Recipes
Build recipes by hand or import one from a URL — per-serving macros in g computed for you.
Favorites & usual meals
Your go-tos learn when you eat them — breakfast suggestions at breakfast, not at midnight.
Copy yesterday
Repeat days repeat in two taps — whole meals or the entire day.
Siri shortcuts
Log by voice while your hands are busy — the entry lands in the right meal slot.
Home-screen widget
Today's calorie ring on your home screen, with protein, carbs and fat left in g on the medium size — no need to open the app to check.
Offline-first sync
Everything works without signal; entries queue locally and reconcile cleanly when you're back — no duplicates.
Wheel pickers & units
Portions in g, oz, servings or household units — weight in lb or kg, distance in miles or km. Units are always visible.
Foods library
Your foods, recipes and favorites in one place — searchable, editable, yours.
Two people, cleanly separated
Invite your partner
A short code or link connects two independent accounts into one household — each keeps their own plan and history.
Shared meals
Log the meal you cooked once; each plate lands on the right diary with the right portion in g or oz.
Log for each other
Either partner can add to the other's day — every entry is attributed, and visibility is mutual by explicit consent.
Dinner picker
Tonight's suggestions scored against what both of you have left — protein-forward when one of you is short in g.
Partner presence
A glanceable strip shows how your partner's day is going — supportive, never surveillance. Member tints stay out of your data.
Instant unlink
Leave or remove — one action severs access both directions immediately, history included.
Understand the week, not just the day
Trends
Weight, intake and expenditure over time — with the adjustment history overlaid so you can see the coaching work.
Weight history
Every weigh-in in lb or kg, editable, with the trend line doing the interpretation.
Micronutrients
Fiber, iron, potassium, and more in g and mg — surfaced as insights when a pattern deserves attention.
Streaks that forgive
No red days, ever. Mark yourself away and the streak freezes instead of resetting; come back after a lapse and the app says welcome back, not catch up.
Light & dark
A dark-first design and a properly designed light theme — follows the system or your override.
Data portability
Export your diary and your weigh-ins as CSV from Settings — one tap, free, no subscription required. Your data is never held hostage.
Ad-free, subscription-honest
MacroPair has no free tier propped up by ads and no engagement tricks. A single subscription funds the food catalog, the coaching engine and ongoing development — and covers both people in a household.
- No ads, no attention economy. The app's only job is your plan.
- No data resale. Your history is not a revenue stream — see the privacy policy.
