Castra is an all-in-one fitness app that replaces workout trackers, progress apps, and coach communication - so everything you need to train smarter lives in one place
Stop juggling a logger, a planner, and a group chat. Castra is one app.
A coach assigns a plan and a check-in form. An athlete logs a workout, asks a question, and gets a reply - all in the same thread the check-in lives in. No email, no separate form tool, no missed DMs.
From HIIT to strength to spinning - the exercise library covers it, whether you train with a coach or on your own.
