Can I vibecode Strong Pro?
// one session, and a personal version you can actually use
The core loop is small enough for a capable coding agent to produce a useful local version in one sitting. For Strong Pro, log workouts, templates, sets, rest timers, and personal history locally. The hard boundary is mobile polish, widgets, watch app, cloud sync, and exercise database, plus hardware data, content, coaching, and trust.

The prompt
One session with a coding agent and your version runs.
Build a personal replacement for Strong Pro 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: log workouts, sets, and rest timers from templates, keep personal history locally, plan moderate routines, and show trends without enforcing restrictive 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
- mobile polish, widgets, watch app, cloud sync, and exercise database
- wearable hardware data
- coach network
- clinical validation
- large content library and social network
Why people still pay
People still pay for Strong Pro 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.

hardware data, content, coaching, and trust
