About

WSP Reader

Features
Read full description

WSP Reader is the companion app for Writing Shed Pro. Its purpose is simple: let you open and read .wsp project files from Writing Shed Pro on iPhone, iPad, and Mac, without bringing the full writing/editing workspace with you. You can also add comments to individual files and save a new copy of the .wsp file that can be opened by Writing Shed Pro. This enables writers to get feedback on their work. Use WSP Reader to: Open exported Writing Shed Pro project files (.wsp) Browse your project structure and files quickly Read formatted text in a clean, focused layout View manuscript flow for continuous reading Add comments for the owner to review Access your content across Apple devices with one lightweight reader app WSP Reader is designed for reading and review, not writing. It does not replace Writing Shed Pro’s editing tools. Instead, it gives you a fast, distraction-free way to review your work anywhere. Ideal for: Proofreading drafts away from your main writing setup Reviewing manuscripts before submission Reading your work on the go Sharing projects for read-only access If you want full project creation and editing, use Writing Shed Pro. If you want clear, portable, read-focused access to your exported projects, use WSP Reader.
