Train without distractions. Re:Do Workouts is a workout planner and training log for people who already know what they train. It brings clarity to planning and execution, because training consistently is hard. Most fitness apps try to tell you what to do. Re:Do helps you do what you already decided to do. Built for people with a plan Re:Do does not teach exercises, muscle groups, or training programs. It assumes you already have a routine - from a coach, a book, or your own experience - and gives you a clear, structured place to organize exercises and workouts exactly the way you want. Just your training, clearly organized: Plan first. Start without friction. Training often fails before it even starts: when you have to remember what to do. Re:Do helps by letting you plan workouts ahead of time: - Organize workouts for the week - See them in a clear calendar view - Start training immediately, without decisions When it’s time to train, the plan is already there. A training player designed for focus Re:Do’s training player is built for execution. It guides you through your workout like a plan standing next to you: - What exercise comes next - How many reps or how much time - When to move on No notifications - No social features - No distractions. Just clear guidance, one step at a time. Consistency is hard. Re:Do respects that Training consistently is difficult. Re:Do doesn’t pretend otherwise. It doesn’t try to motivate you or promise results. It simply removes friction from planning and execution, so you can put your effort where it belongs: into the training itself. Structure won’t make training easy, but it makes consistency possible. Who Re:Do Workouts is for - People who already train or follow a program - Anyone tired of bloated fitness apps - Users who prefer structure over motivation - Athletes who want clarity, not noise If you want a calm, precise tool to support your training, Re:Do Workouts is built for you. In-app purchases: Re:Do Workouts includes optional purchases. Re:Do Pro is a separate one-time in-app purchase that unlocks personal Pro features, including expanded workout limits, recurring schedule options, schedule sharing, progress/stat views, optimization suggestions, and the Apple Watch companion app. Program Distributor seat plans are separate auto-renewing subscriptions for users who want to publish and manage shared programs for members, teams, clubs, or followers. The free app can still be used to create, organize, and run workouts without purchasing these upgrades.
