Report a Bug or Request a Feature

The fastest way to report a calculator error, broken page, or feature idea is to open a GitHub issue. Please include the calculator name, the inputs you used, and what you expected to see. Screenshots are helpful — the RPE Calculator has a built-in screenshot tool.

Common things worth reporting: incorrect formula output, display issues on specific devices or browsers, accessibility problems, or features that would make the tools more useful for your training.

Content Feedback and Guide Suggestions

Our guides are written to be accurate and practical for strength athletes. If you spot a factual error, outdated recommendation, or a topic you'd like us to cover, let us know via email or GitHub. We take content accuracy seriously — every guide is reviewed against peer-reviewed sources and established coaching practice.

We're always looking for guide topics that would genuinely help lifters. If there's a concept, programming approach, or training question you'd like to see covered in depth, suggest it via email or GitHub. We prioritize topics that come up repeatedly in the strength training community.
