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.
Replacing a paid app means you set it up and keep it running: hosting, updates and backups can be on you. What you give up.
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.
