Can I vibecode MacroFactor?
// buildable in a weekend, but real gaps stay open
The core loop is buildable, but a dependable replacement becomes a real weekend or multi-day project. For MacroFactor, record user-chosen nutrition information and show neutral trends without aggressive targets. The hard boundary is food database, adaptive coaching models, mobile capture, and ongoing nutrition expertise, plus hardware data, content, coaching, and trust.

It is not close. The prompt below rebuilds a piece, not the product.
Gioco editoriale: il verdetto dice se un agente può, l’indice se conviene.
What you build
Record user-chosen nutrition and wellbeing information, plan moderate routines, and show neutral trends without diagnosing, shaming, or enforcing restrictive or aggressive goals.
what you need
- iOS or Android device
- optional HealthKit or Health Connect permission
- local storage

The prompt
A weekend with a coding agent. The gaps that stay are right below, under “what you lose”.
Build a personal replacement for MacroFactor in an empty repository.
Use React Native with Expo, TypeScript, SQLite, and HealthKit or Health Connect only when explicitly enabled; do not offer alternative stacks.
The core loop is: record user-chosen nutrition and wellbeing information, plan moderate routines, and show neutral trends without diagnosing, shaming, or enforcing restrictive or aggressive goals.
Make the first run work locally with one documented command.
Store all user data locally by default and make export straightforward.
Put secrets in .env, ship .env.example, and never commit credentials.
Create optional logs for activity, sleep, mood, energy, and personal notes with editable units.
Let the user build moderate routines and rest days without weight-loss targets, punishment, or competitive pressure.
Request health-platform permissions per data type and work fully without granting them.
Show weekly patterns and consistency with neutral language and no diagnostic or body-image judgments.
Add reminders that can be muted, data export, account-free local use, and full deletion.
Include a clear statement that the app is not medical care and should not replace qualified advice.
Include clear empty, loading, success, and recoverable error states.
Add input validation, safe filenames, and graceful handling of unavailable APIs.
Write focused tests for the core transformation and one end-to-end happy path.
Create a README with setup, architecture, permissions, data location, and backup steps.
Do not add accounts, billing, telemetry, analytics, or a hosted control plane.
Deliberately leave out medical diagnosis or treatment.
Deliberately leave out extreme exercise or restrictive-eating coaching.
Deliberately leave out wearable hardware, human coaching, and a large social network.
Finish by running the tests and listing the exact commands used. Prompt generated from the data on this page, not reviewed by hand yet. In English on purpose — it is the language coding agents work best in.
What you lose
- food database, adaptive coaching models, mobile capture, and ongoing nutrition expertise
- wearable hardware data
- coach network
- clinical validation
- large content library and social network
Why people still pay
People still pay for MacroFactor because people pay for polished mobile capture, trusted content, hardware integration, and coaching rather than the basic logbook. The recurring cost buys sensor permissions, data quality, notifications, safety language, accessibility, sync, privacy, content review, and support, not just the visible interface.
