The AI weight loss app that does the math for you

Sustainable weight loss is a math problem (calorie deficit) plus a behaviour problem (sticking to it). Swoodie automates the math so you can focus on showing up.

Most weight loss apps assume you can correctly estimate your TDEE, calculate macros, log every meal accurately, and stick to a plan you built yourself. That works for some people. Most quit by week three.

Swoodie is built to remove those failure points. BMR/TDEE is auto-calculated. Daily targets are personalized. Logging is photo-based. And the AI Meal Planner builds plans that already match your deficit — so adherence is the only thing you have to do.

Why weight loss tracking usually fails

  • Generic 2000-calorie targets that don’t match your body
  • Manual logging burnout (10 minutes after every meal)
  • Macro math anxiety when you’re not a nutrition nerd
  • Meal planning takes longer than the actual cooking
  • Plateaus that nobody explains how to break

What Swoodie does for weight loss

  • Personalized BMR/TDEE auto-calculation

    Enter age, height, weight, activity level once. Swoodie sets your daily calorie + macro target for cut, maintain, or bulk.

  • Product Check — packaged-product quality score

    Scan any packaged product's barcode for an instant 0–100 quality score and see the additives and labels behind it, so you can compare options at a glance. Free scan + score; better swaps and Ask AI are Premium.

  • Ready-made diet plans

    Load a curated 7-day plan into your planner and tweak it to taste — a structured week of meals without building one from scratch.

  • Step Counter

    Connect Apple Health or Health Connect and your daily steps add calories back to your goal, so an active day gives you a little more room to eat.

  • AI photo + barcode calorie counter

    Log meals with a snap or scan — no database hunting, no kitchen scale required for most foods.

  • AI Meal Planner that hits your deficit

    Pick days, get a complete plan with calories that already land on target. Auto-fills snacks to close gaps.

  • Weight + BMI tracker with weekly reminders

    Log weight once a week, see BMI trends over months, get gentle nudges on your chosen day.

  • Solo Challenges for accountability

    Personal goals like ‘7 days under target’ — gamifies adherence without needing a partner.

  • Intermittent fasting tracker

    Intermittent fasting is one of the most popular weight-loss methods — track a 16:8, 18:6, or OMAD window with a live timer, free.

  • Text-to-Nutrition

    Skip the database search — type ‘two eggs and toast’ and get calories, macros, and a health score instantly.

  • Wellness Duels

    Stay accountable by going head-to-head with a friend on a daily check-in challenge — adherence is easier with a little stake.
