Here is the app`s compatibility information: Compatible with iPad. Requires iOS 3.2.1 or later
Bottom Line: For more information about A-Truss HD check developer Sompop Pimsen`s website : http://

This would be a great application if it worked It provides no moments in members crashes frequently limited constraints has limited results I have no idea what this ap is good for if you can t constrain nodes or calculate moments     Does not work JsThoughts1

The app frequently crashes after trying to edit nodes and or truss members         Frustrating Citybound76

The section properties are in SI units with no way of changing them It would have been nice to know that beforehand Can I have a refund             Chunky Houdinic4

It doesn t work on iOS 8     Needs an update -Ashkan93-

This app is very buggy which is disappointing because it has a lot of potential It would also be nice if it had US wood and steel sections built in There are a lot of different truss profiles built in The app crashes at random times frequently This needs to be fixed for this app to be worth anything     Buggy NinjaoftheNasty

First it isn t supper stable but not so bad as to be terrible The calculations are good and that is definitely helpful when you are wanting a quick look However there are some glaring issues with this as a really useful tool for an engineer First and the biggest in my mind is the fact that the program doesn t account for the distributed load of the truss itself I designed a truss that shouldn t have been able to support itself but the program doesn t account for the weight of the truss materials and because of this it told me that it was just fine with a very small load which wasn t true This wouldn t be quite so bad if it allowed you to add distributed loads but all that you can do is add loads at each node This means that you have to run some load calculations by hand and then add approximate loads at each node for the weight of the truss itself Second is the lack of an undo Again this wouldn t be a big deal except that all changes are accept once you click out of a field This means that if you accidentally click in the wrong field and make a change there is no way to cancel or undo the change If they were to make these changes along with adding the capability to more easily make numerous versions of a single truss For instance adding the capability to make a copy of an existing truss as a starting point for a new truss This would easily be a four star program To get a five star they would have make these changes and address the many stability issues             Good but not great mknopp

Too much bla bla and not enough information about the app use Very difficult to edit the information It is not possible to get out of edit mode when using the calculator must use the iPad exit button since there s no way of returning to the working model A very poor program certenly not worth the 10 bucks         Not so hot Rabelom

The setup of a truss was fairly easy once you get the hang of the quirky approach required I have three hangups with this app First and this is the most serious You can t create a new truss by copying an existing truss and then modify it Trying different design variations of a concept is what structural design is all about Second the available units needs to include Kips and Kips sq in Third there does not seem to be any way to add section properties from another country than the South Africa default Without these capabilities A Truss is 9 99 toy rather than an engineering tool             A Truss HD Engineer B

The app has a lot of potential The trusses are great But the app crashes constantly while I am playing with the truss Please fix I would also like it if the nodes part acted as an excel and data could be input         Constantly crashes freddy53
