This is a source-based comparison, not a hands-on speed or reliability test. We separate the two products' documented jobs: Hevy combines manual logging with a Pro Trainer workflow, while Strong emphasizes routines, history, charts, and Apple Watch logging. We compare those documented differences, free and paid terms, and platform support without assigning a numerical fit score or claiming training outcomes.
We also keep app categories separate. Hevy is best for lifters who want free social logging or paid Pro Trainer planning, while Strong is best for lifters who want a quiet, manual logging workflow. That means the winner can change depending on whether you care most about logging, generated sessions, Apple Watch, social motivation, or coaching.
Logging workflow
How the documented workflow covers starting a workout, entering sets, editing mistakes, and checking history.
Planning help
Whether the app helps decide the workout, adapts around equipment, or leaves programming fully to the user.
Progression clarity
How clearly the app documents next-step decisions, progression rules, or the limits of its planning help.
Value
How much useful strength-training workflow is available before paying, and what paid plans unlock.
Platform evidence
How clearly official sources document phone, watch, Android/iOS, and offline boundaries.
This matchup uses documented workflow trade-offs instead of a numerical editorial total. Pricing, platform support, and free-tier limits should be rechecked from official sources before purchase.
