How it works

Most apps count what you ate. Adaptin is one system for what your body does with it.

What you log Search 13,600+ foods in English and Arabic, scan a barcode, or quick-add macros. Meal slots, favorites and copy-yesterday keep it to a few taps, including offline.

What it learns Weight trend plus intake trains an adaptive TDEE. The target moves as the data sharpens, and history never rewrites itself when the model updates.

What it catches Tea within an hour of iron cuts absorption ~50%. Adaptin flags the clash, explains the magnitude, and hands you the fix.

01Pillar · Energy

Your real metabolism, measured.

Adaptin learns true expenditure from your weight trend and what you eat, then adjusts the daily target as confidence climbs from calibrating to high. No fixed formula. No crash when a scale reading jumps.

  • 01 Bayesian blend with a Mifflin–St Jeor prior that decays as your own data accumulates.
  • 02 Plan vs trajectory: committed rate against observed pace, with a daily-kcal lever to get back on plan.
  • 03 Activity bonus (opt-in) earns back bounded calories on unusually active days. It never contaminates the regression.

Know exactly what's missing.

Four macros and 49 micronutrients on a rolling 7-day view. Adaptin flags what's low, shows whether it came from food or supplements, and points you to the food that fixes it, before you reach for a pill.

  • 01 53 nutrients, surfaced in three tiers: essentials, complete, advanced (including amino acids and carotenoids).
  • 02 Region-tuned thresholds (iron at 80%) and RDAs by sex, with upper-limit alerts.
  • 03 Food-first suggestions: previously-logged → Arab staple → catalog, each loggable in one tap.

03Pillar · Timing

Timing changes everything.

Tea within an hour of iron cuts absorption by roughly half. Most apps never notice. Adaptin catches the clash, explains why it matters, and hands you the fix: move the iron and it counts in full.

  • 01 Real magnitudes: “reduces absorption ~50%”, always with the fix attached.
  • 02 Windowed evaluation on food or supplement log: iron × tannin, calcium, phytate; vitamin C as enhancer; levothyroxine as critical.
  • 03 Bundled daily summary in Notification Center instead of a popup after every bite. Synergy badges when timing is right.
Interaction foundFig. 03
Heads up
Warning

Tea or coffee within 1 hour can cut iron absorption by 50–80%.

May reduce absorption ~50–80%

Fix
Take iron 2 hours before or after tea/coffee. Pair with vitamin C.

• Iron + Tea (black, brewed), 25 min apart

04Pillar · Consistency

Show up. Watch it add up.

A daily nutrition score, a logging streak with milestones, and a 90-day heatmap that turns steady effort into something you can see. Small, honest wins: no guilt, no broken-streak shame.

  • 01 Daily score 0–100: calories 50 pts plus protein / carbs / fat, scored inside ±15% bands.
  • 02 Streaks with milestones from 7 to 365, and a shareable streak card.
  • 03 Consistency heatmap: ~90 days, three modes: score, logged, weight.

05Pillar · Stack

A schedule that belongs to your day.

Evidence-based timing around wake, sleep, workouts and meal slots. Separation constraints in both directions, a caffeine cap six hours before sleep, empty-stomach anchors, and a Ramadan mode that collapses it into suhoor and iftar.

  • 01 ~51 supplements with evidence-strength badges and timing rules for each.
  • 02 Ramadan-aware: iron at suhoor without tea, calcium at iftar, notifications that follow the fast.
  • 03 Check-off + backfill. Mark taken on any past day. Push reminders with a “mark as taken” action.

Rules are data-driven, not vibes: 47 interaction rules covering iron × tannin / calcium / phytate, vitamin C as enhancer, heme synergy, zinc/calcium competition, fat-soluble vitamins + fat, and levothyroxine.

  • 01 Hypothetical pre-log check: see the clash before you commit the bite.
  • 02 Per-rule dismissal and “why we flag this” evidence detail, always on tap.
  • 03 Positive synergy when you time vitamin C with iron. The engine praises good timing too.

07Spotlight · Food first

Eat this to fix it.

Deficiency under 70% RDA on a 7-day average surfaces a bento of what’s low. Suggestions rank what you’ve already logged, then Arab staples, then catalog foods, each one tap to log. Supplements are the fallback.

  • 01 Previously logged foods first, the thing you’ll actually eat again.
  • 02 Staples: kabsa, shawarma, hummus, labneh, dates (the food the region actually eats).
  • 03 Food vs supplement breakdown on every nutrient, so you can see what’s doing the work.

08Spotlight · Honest history

Yesterday’s target stays yesterday’s.

Custom fixed or adaptive kcal modes, percent-based macro splits, and per-day snapshot freezing so a model update never rewrites the past. The score you earned on Monday is the score Monday keeps.

  • 01 Frozen daily snapshots: kcal and macros locked at end of day.
  • 02 Full model transparency: r², SE, weekly adjustments, “how this was calculated”.
  • 03 Export everything as JSON, or delete the account in two taps. Your data, yours.

How Adaptin compares

Every tracker counts calories.
Only one tracks absorption.

The big apps are genuinely great at what they do. But none of them watch the timing between your food, drinks, and supplements: the part that decides whether the nutrients actually land.

Absorption timing = 47 evidence-based rules that flag clashes like tea cutting iron absorption, each with the fix. Comparison reflects publicly available features; every app is best at its own strength. Longer write-ups: vs MyFitnessPal · vs Cronometer.

Most apps count what you ate. Adaptin learns what your body does with it.
Not just a tracker. A metabolic OS.

Why it exists
