The easy and fastest way to analyze the 2D-Truss problem right on your iPhone & iPod Touch. Featuring: • Standard Truss Templates: with the standard truss template (18 types of truss for initial version) , you can easily create and config your truss as required. • "Custom Truss"; If the built-in standard truss template doesn't match your requirement, "Custom" your own Truss is also easy to create due to the Node & Element generating features. • Unit Flexibility: very flexible in Units system, you can choose any units at your convenience without the requirement to restart the application and the unit system is saved per your truss's project. For example you use m. as node coordinations while you choose mm. for the deflection of the nodes or you can even choose in. or ft. for nodes's deflection (if you really need). • Buit-in material sections library where you can adjust any material's properties with no effect to other truss project. The options to create your own material library will be available for the next update. • PDF Reporting: All result information of your truss are shown in PDF and also you can email this result. ## Key features - Standard truss templates (18 types) - Custom truss creation - Flexible unit system - Built-in material library - PDF reporting and email export ## Recent user reviews (10 of 20) All indexed reviews: https://appshunter.io/ios/app/a-truss/id412684176/reviews.md ### 1/5 — WRONG CALCULATIONS!!! *2025-09-03* The App looks very nice and interactive but the calculations are not accurate and there is not even a feedback option to tell the developer what’s going wrong. This clearly indicated to me that they just developed an app, put it on App Store, and job done. Not caring what happens. ### 1/5 — Don’t use this app *2024-10-15* Not working properly, I want my money back ### 1/5 — Crashes (refund wanted) *2017-10-31* The app looks great but as soon as i add a vector the app crashes. I would like a refund. ### 1/5 — Crashes *2017-03-15, version 3.2* The app is handy but it crashes every now and then making it useless. Dont ever purchase this app. ### 1/5 — Demand refund *2017-03-01* Make and app and make it right before y'all falsely advertise. DO NOT GET. SCAM AND WILL CRASH ### 1/5 — WASTE OF MONEY *2016-11-22, version 3.0* DO NOT DOWNLOAD. This app does nothing but crash and is a complete waste of £3.99. You should give people their money back!! ### 1/5 — Dank *2016-10-19* Crashed literally 2 minutes after i used it. Can't use any custom templates. Only the default templates work. ### 1/5 — Crashes!!! *2016-09-22, version 3.0* Keeps crashing as I draw a node, very annoyed and not worth a second look... ### 5/5 — Muy buena app *2016-06-08* Faltan corregir algunos errores pero en general funciona muy bien ### 1/5 — App crashes *2016-03-21* The app shuts down when trying to build a custom truss. Waste of $5! 😒 ## Frequently asked questions about A ### What is A-Truss? A-Truss is a mobile application designed for analyzing 2D truss problems.
