Train with clarity. Log without friction.

Trenny is a fast, focused workout journal designed for the iPhone. Start a session, log sets in seconds, and build a training history you can actually use to get stronger.

The philosophy is simple: Get in, log the work, and get out. We don't believe in cluttered feeds or distracting social features. We believe in progressive overload, consistent effort, and data-driven results. Trenny gives you the tools to analyze your performance without the bloat of traditional fitness apps.
