Logging a meal and totaling calories and macros is ordinary CRUD. The reason people actually use MyFitnessPal is its enormous crowd-sourced food database with barcode scanning — the data, not the logging UI, is what took a decade to accumulate.

Two real costs, not just "free": the AI agent's own usage, and hosting once it's running. Both are estimated from this app's own effort rating and component list — see the assumptions on the method page.
| AI agent — with a subscription (Claude Pro/Max, Cursor, etc.) | $0 marginal |
| AI agent — pay-per-use API, no subscription | $43–$86 one-time |
| Hosting, once it's running | $0/mo (free tier) |
| Domain name, if you want your own | ~$12/yr |
MyFitnessPal costs $19.99/mo. Even paying per-token with no subscription, and accounting for hosting, this build pays for itself in about 5 months.
