Manage the work breakdown structure (WBS) in the list and tree diagram. Construct the work package tree and update the estimate; import work items from MS Excel and export the work breakdown structure to PDF, Excel, and image files. Also, we can convert a work breakdown structure to a project plan file in the QuickPlan app.

The WBS is a hierarchical and incremental decomposition of the project into phases, deliverables, and work packages. It is a tree structure that shows a breakdown of the effort required to achieve a goal, such as a program, a project, and a contract.

Mobilinked WBS is THE easy-to-use WBS management app for the iPad. Using natural gestures on a clean interface makes WBS management more convenient, faster, and more efficient than ever before. Visualize and simplify the work breakdown structure in the outline and diagram view to break down work elements and determine labor, material, and total costs for each component. The app automatically adds costs up to the element hierarchy, and supports continuous and mass tracking.

The WBS can be exported to image, Excel, and PDF files AND converted to QuickPlan (https://itunes.apple.com/app/id621375878) as a project plan.

The WBS supports mass entry of work items and import of work items from an MS Excel file.

Bottom chopped off on iPad Pro 11” widescreen

Hello Team,

I’ve just purchased WBS app for iPad and noticed that the bottom of the screen is chopped off on iPad Pro 11” widescreen format when I select an item. The menu on the bottom is chopped off and I’m not able to fully use the app. Please optimize the app for 11” widescreen format and release an update ASAP.

FYI, the new iPad 10.9” is also widescreen and may have similar issue. Also, your other apps may have similar issues with widescreens.

2. It badly needs drag and drop boxes across columns in the layout screen. Currently, it seems deleting and re-adding the boxes is the only way to reorganize.

3. Category is not available for some boxes.

Great app, will give 5 stars on resolving these issues.
