FAQ
Common questions about SuperFlex features
Answers to common feature questions before you start.
Which SuperFlex features are free?
Workout logging, core templates, muscle recovery, Apple Watch support, HealthKit sync, and data export are included in the free experience. Pro adds guided progress photos, deeper strength analytics, and expanded template capabilities.
Why does the features page link to separate detail pages?
The hub shows how the full system works together. Each detail page covers workflow details, edge cases, and feature-specific questions without turning the hub into a long manual.
Is SuperFlex only for powerlifters?
No. Powerlifters get the strength-trend tools they expect, and the same logging, templates, progress photos, and recovery context also work for bodybuilders, hybrid lifters, and anyone training with intent.
Can I use SuperFlex without locking my data inside the app?
Yes. SuperFlex supports open export formats and is designed around data ownership. SuperFlex earns trust by staying useful, not by trapping your training history.
Train better with tools you will actually use.
