By using this application your device will recognize the different cards with the images of packaging models produced by PCD Packaging, and by doing so you will visualize the 3D models of the packages on your screen, analyze them and interact with them from different angles. These cards will be given to you by a representative of the company at exhibitions or industry events or you will receive them in your email when you ask for them in the contact email of the PCD Packaging website.
MPP Viewer
Read full descriptionHide full description
Open supported Microsoft Project MPP schedules on iPhone and iPad without uploading project data or subscribing to a full authoring suite. GanttPeek is a focused, read-only viewer for people who receive plans and need the answer quickly. READ THE SCHEDULE - Browse and search the task hierarchy - Navigate a pinch-to-zoom Gantt timeline - Inspect dates, durations, hierarchy, and relationships when present - Review extracted resource names and basic assignments - Share a paginated PDF schedule report or task-table CSV PRIVATE BY DESIGN MPP files are processed locally on your device. GanttPeek has no account, advertising, analytics SDK, cloud parser, or activation server. It receives access only to a file you select and never writes back to the source MPP. EXPLORE SAFELY The fictional Harbor Studio Launch schedule is included with every install, so you can explore the interface and exports before opening a private file. FORMAT COMPATIBILITY The verified parser accepts the MPP8, MPP9, MPP12, and MPP14 binary families, including the shared Project 16.x / MPP14 family used by Project 2021, Project 2024, and the Microsoft 365 desktop client. Exact modern originating editions cannot be distinguished from that shared family. Password-protected files are not currently supported. Baselines, progress, constraints, notes, real calendar exceptions, custom fields, resource capacity and costs, source critical-path flags, and some assignment details are not currently extracted and are disclosed inside the app. GanttPeek is not a certified scheduling or contractual-verification system. GanttPeek is independently developed by Eutopix Labs and is not affiliated with, endorsed by, sponsored by, or certified by Microsoft.

Verdict
The clearest difference is update cadence: MPP Viewer at weekly against PCD's every 3 weeks. PCD's advantage is iOS requirement (9.0 vs 17.0). On price, ads, in-app purchases and device support there is nothing between them.
