Axiome vs Hevy: Connected Trajectory vs Isolated Gym Logging
The verdict
Axiome has a gym log with more than 1,600 exercises, set types, and a muscle diagram, and keeps it beside your sleep log, habits, and tasks. Hevy is a dedicated gym logger with a social feed that focuses on training alone.
- Your workouts sit beside your sleep log and habits, and Insights compare them, rather than keeping gym data on its own.
- A library of more than 1,600 exercises with photos, and a muscle diagram for each split.
- Integrated Eisenhower matrix and habit tracking replace the need for multiple separate productivity applications.
- No social feed and no ads, so there are no public metrics to compare yourself with.

Common questions
Axiome vs Hevy, in detail
Axiome is a gym log for lifters who also want sleep, habits, and tasks in the same app. It includes more than 1,600 exercises with photos and written steps, warm-up, drop, and failure set types, split planning, personal records, progress charts, and a body diagram of the muscles each split covers. It does not have RPE, a rest timer, or a plate calculator yet, and it has no social feed, so if those matter most, Hevy may suit you better.
