Editorial disclosure: Gainz publishes this comparison and makes the Gainz app. Product details were last reviewed July 15, 2026 against the Strong, Hevy, and Gainz App Store listings, plus Gainz's current plan configuration. Features, plan limits, and availability can change.
The Landscape
Strong and Hevy both cover the fundamentals of workout logging, but their product emphasis is different. Strong presents a traditional training log, while Hevy puts community features next to planning and progress tools. The better fit depends on how you want to train and review data.
Strong: The Traditional Logbook
Strengths: Its current listing emphasizes a simple logging workflow, custom routines, progression graphs, CSV export, and a fully featured Apple Watch app.
Trade-off: Its free offering limits the number of custom routines. Review the current App Store listing to decide whether its paid features fit your program.
Hevy: Training With a Community Layer
Strengths: Its current listing highlights routine planning, detailed progression graphs, Apple Watch support, and the ability to follow friends and share workouts.
Trade-off: Community is a central part of the experience. That can be motivating if you train socially, but it may be unnecessary if you only want a private logbook.

The Third Option
If neither product emphasis fits, Gainz is another option for lifters who want quick set entry, structured programs, weekly progress, PR history, and offline logging.
Gainz is free to start on iPhone. Apple Watch support is included with Premium, and CSV export is available on Pro and Premium. Check each live App Store listing before choosing because plan limits and features can change.
