This app is easier on a desktop or laptop, where you can draw and edit the truss directly on the board. On a phone that drawing isn't practical — so on mobile you build the truss with the buttons instead. It still works fully; it's just a little more tapping.

Tap Input Joints, then Assign Members from Joints, then Input Joint Loads — or let Scan auto-fill the truss from a photo (optional). When you're ready, tap Results to solve — or Detailed Solution for the full step-by-step.

Calculating forces will spend 10 Ebora Points. This single charge covers both the Results and the step-by-step Detailed Solution.

Quick check before you spend:

• Your joints and their supports (pin / roller) are right.
• Every member connects the correct two joints.
• Your joint loads (size and direction) match your figure.

You don't need to scan. You can input the joints, members, supports and loads yourself for free — scanning is an optional paid shortcut that types them in for you.

EboraBot uses AI to fill in your truss — the joints, members, supports and loads — so you don't have to type a big problem by hand. It inputs the truss for you; it does not solve it.

• Accuracy is about 95%. On a dense diagram it can misread a number, a load angle, a support, or which way a diagonal runs.
• You must visually check everything it fills in — compare the joints, members, supports and loads against your figure and fix anything wrong.
• Only after you've verified it do you press Calculate Forces to solve.
• Scanning and solving are charged separately in Ebora Points, so review carefully before you solve.
