AS SEEN ON Forbes, Cult of Mac, The Next Web, MakeUseOf, MacAlert!, Apple RSS, Envato Blog, Duct Tape Marketing, AppleBase, GeekZone A WRITEMAP OUTLINE PAINTS A THOUSAND WORDS WriteMapper was built to leverage the visual nature of mind maps to give you a bird's-eye view of your writing structure. Just one glance is all it takes for you to get a good feel for the flow of your work. In doing so, you get a comprehensive yet clear picture of what's going on in your content. And, if you need to rearrange your writing sequences or move stuff around, it's as simple as drag and drop. BRAINSTORM YOUR WAY THROUGH WRITER’S BLOCK Ever write down the title, and then face a mental struggle with the rest of the blank page? WriteMapper helps you overcome writer's block by turning your writing process into a brainstorming exercise. This allows you to rapidly and relentlessly generate ideas and points for your writing. Just spend a couple minutes on this quick-fire process, and before you know it, you'll have a fully-formed content structure all ready to go! DISTRACTION-FREE WRITING Each node on the mind map has a content section you can jump in to edit at anytime. Besides being able to style and format your writing however you like, you can also edit the title of this sub-point from this view as well. The distraction-free writing mode helps you shift gears from the all-aspects-considered nature of the mind map outline, to the focused task of detailing the contents of the individual sub-point you're zoomed in on. PLAYS WELL WITH TEAMMATES WriteMapper uses the nested structure of a mind map to automatically create and export a text document for you, right in your computer's file system. You can choose from a variety of file formats, including Markdown, HTML, Microsoft Word, plain text and Rich Text Format. You can then edit the exported document in your text editing app of choice, to give that final draft the polish it needs to bring it to completion. With this supercharged content generation workflow, you'll get your writing done in no time at all! HIGHLY PRAISED "It has the perfect balance of elegance and features, and the text-editor itself is killer."—Charlie Sorrel, Cult of Mac "WriteMapper is such a powerful tool. This workflow is so logical and intuitive."—Michael Levy "Holy graphic design, that's one beautiful interface."—/u/bengiannis ALL THE POWER OF IOS WriteMapper was reworked from the ground up to be deeply integrated with and optimised for an incredible iPad experience. Here’s a couple of features and capabilities which we’ve leveraged from the power of iOS, the world’s most advanced mobile operating system, to help you do your best work: 1. Files With the help of the new Files app, you can easily save, sync and access your WriteMaps (.writemap files) across devices. 2. Drag and Drop Magically move text and images from other apps into the distraction-free editor, or rearrange the nodes in your WriteMap by dragging them around. 3. Keyboard Shortcuts Typing is even better on the iPad with an external hardware keyboard; and we’ve made it even easier to keep the typing flow going by integrating multiple handy keyboard shortcuts. 4. Split View You can also have the app open side by side another app with the Split View feature of iOS. No more constant switching between multiple apps! 5. Apple Pencil Support The app also plays nice with your Apple Pencil. It's just another thing that helps make WriteMapper for iPad more versatile, powerful, and natural than ever. WRITEMAPPER ON YOUR OTHER DEVICES Get WriteMapper for your Mac or Windows desktop computer to experience the full power of working on your .writemap files across your devices (sold seperately), accessing your WriteMaps using your preferred cloud syncing service.
