Can AI replace Hevy Pro?
The core loop is small enough for a capable coding agent to produce a useful local version in one sitting. For Hevy Pro, log workouts and routines locally with neutral progress charts. The hard boundary is mobile apps, social features, watch integration, sync, and polished tracking, plus hardware data, content, coaching, and trust.
01What it costs
Checked Aug 14, 2026 · source: hevyapp.com.
| Plan | Monthly | Billed yearly | What you get |
|---|---|---|---|
| Free | Free | Free | 4 routines, 7 custom exercises, and stats history limited to 30 days or 3 months depending on view; 400+ built-in exercises |
| Hevy Pro | $2.99 | $2/mo | Unlimited routines and custom exercises plus all-time graph/history access |
| Hevy Pro Lifetime | — | — | Lifetime Pro access |
Hidden costs: Hevy Coach is a separate product and can create a second subscription. App-store legacy/alternate monthly offers can differ from the public $2.99 rate.
02Could AI build it for you?
The core job: Log workouts and routines locally, plan moderate training, and show neutral progress charts without diagnosing, shaming, or enforcing restrictive goals.
What a working version needs:
- iOS or Android device
- optional HealthKit or Health Connect permission
- local storage
Editorial comparison targets the Pro plan and a personal general-wellbeing tracker DIY substitute. Recheck price before merge.
03What you'd give up
- mobile apps, social features, watch integration, sync, and polished tracking
- wearable hardware data
- coach network
- clinical validation
- large content library and social network
People still pay for Hevy 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.
04Free and cheaper alternatives
Sets, timers, plans and charts live on the phone instead of behind a lifetime unlock.
Versus paying: LiftLog lacks Hevy's large social community, polished exercise discovery, coaching-style routine marketplace, wearable integrations, and cross-platform sharing experience.
liftlog.online →A no-ad Android lifting log that has been doing the basic job for years.
Versus paying: FitNotes is Android-only and gives up Hevy's iOS/web presence, social feed, friend comparisons, richer exercise media, and polished cloud synchronization.
fitnotesapp.com →Workouts, sets, timers and charts on your own server; setup day counts as cardio.
Versus paying: wger is broader but its logging flow, exercise media, offline/mobile polish, social layer, and instant setup are less refined than Hevy's.

Paste this into an AI coding tool (such as Claude, ChatGPT, Lovable or Replit) to build your own version.
Build a personal replacement for Hevy 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 and routines locally, plan moderate training, and show neutral progress charts without diagnosing, shaming, or 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.
