CatalystAgile Trainer Macro Builder

Client calorie and macro targets without a monthly subscription.

What you get

Mifflin–St Jeor BMR, activity multiplier, goal adjustment and a macro split you control — the same maths the $25–$75/month apps run, on your own device, for one payment.

  • Mifflin–St Jeor BMR and TDEE
  • Cut / maintain / bulk goal adjustment
  • Protein, carb and fat split by ratio or g/kg
  • Per-meal breakdown
  • Client handout export

What's in the ZIP

  • Full PWA source (HTML/CSS/JS)
  • README-USER-GUIDE.md
  • GROQ-OPTIONAL.md hook
  • LICENSE.md (single-buyer perpetual)
  • Logo + favicon assets
  • 1 free hosting walkthrough

Hosting your copy

Drop the unzipped folder into Cloudflare Pages, Vercel, Netlify, or even a S3 bucket. The PWA works as a static site — no Node server, no database, no API key required. Add a free Groq API key later if you want AI-enhance mode (instructions in GROQ-OPTIONAL.md).
