A-Truss3D Pro is a structural analysis and visualization app for 3D truss systems. Create, edit, calculate, and review truss models directly on iPad with an interactive 3D canvas, engineering units, material properties, load cases, and direct stiffness method results. Design trusses by defining nodes, members, supports, materials, and loads. Visualize geometry, member labels, load arrows, reactions, deformations, dimensions, and force states with clear 3D controls. Review calculated displacements, reactions, member forces, stiffness matrices, equilibrium checks, and summary reports in one workflow. Key Features • Interactive 3D truss and double-layer space truss modeling • Node, member, material, load, and support editing • Direct stiffness method calculation • Member force results for tension, compression, and zero-force members • Node displacement and reaction results • Deformation visualization • Stiffness matrix and equilibrium report views • Custom unit templates and precision settings • Sample truss catalog for quick starting points • PDF report generation and preview • Canvas display controls for labels, dimensions, loads, reactions, font, and scale A-Truss3D Pro is built for engineering students, educators, and structural professionals who need a focused tool for creating and checking 3D truss behavior.

About

Task Quadrant

Features
Read full description

We were inspired by the Eisenhower Method and created an app that helps you efficiently manage your tasks by organizing them based on urgency and importance. This approach allows you to quickly set priorities and avoid chaos and overload. The simple and intuitive interface makes planning easy and accessible. Flexible task management: You can quickly and efficiently change the quadrant of each task based on its priority, adapting your plan in real time. Integration with Calendar and Reminders: Tasks in the “Urgent and Not Important” category work with iPhone Reminders to notify you of timely but minor tasks. Tasks in the “Not Urgent and Important” category sync with your iPhone Calendar, helping you plan significant activities in advance. Intuitive interface: Task management doesn’t require complex setups. Just create a task and set its priority. If you’re new to the Eisenhower Matrix, this is a great way to learn how to prioritize tasks and manage your time effectively in both work and personal life. Stay focused on what truly matters and keep your priorities under control every day. Additional information: https://www.apple.com/legal/internet-services/itunes/dev/stdeula/
