Strong Pro alternatives: 3 free & open-source picks
Curated, verified, and actually free. No trials, no crippled tiers. Star counts and last-activity dates checked by hand, not scraped and forgotten.
Workouts, sets, timers and charts on your own server; setup day counts as cardio.

dataHosted records live in wger's service; self-hosted users keep accounts, workouts, nutrition, measurements, and exercise data in PostgreSQL plus persistent media volumes, while the mobile client maintains an offline local database and syncs.
vs Strong Prowger's mobile and self-hosted workflow is less immediate and polished than Strong's fast local logging, template editing, rest timers, history, and wearable integration.
setupNone for the hosted service or mobile app; self-hosting immediately requires Docker Compose, PostgreSQL, Redis/sync services, a reverse proxy, mail, backups, and upgrades.

Sets, timers, plans and charts live on the phone instead of behind a lifetime unlock.

enginesThe optional paid routine generator uses Anthropic Claude; normal workout logging and charts do not require an AI service.
dataWorkout plans, exercise history, sets, and measurements are kept on the device and can be exported as plaintext; optional social/backup features publish encrypted data through the project's backend.
vs Strong ProLiftLog covers sets and routines but lacks Strong's mature Apple Watch workflow, broad platform polish, exercise library, chart depth, and long-refined template editing.

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. If none of that applies to you, any pick above saves $59.88 a year.
Is there a free alternative to Strong Pro?
Yes: wger, LiftLog, FitNotes. Every tool on this page is either open source or genuinely free to use long-term: no trials, no crippled tiers.
Should I just build my own Strong Pro?
Our verdict is YES. 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. If you'd rather build, the exact one-shot prompt is free at canivibecodeit.com/strong-pro.
