### 1/5 — The app used to work

*2020-09-14, version 3.0*

The earlier version used to work, this last version has the problem that only works with concentrated loads and that is it. Seriously no good any more, you can not use all the possibilities it should have. Maybe they fix it.

### 4/5 — Little confusion with the loads

*2015-04-12, version 1.6*

I have loved using this app on Engineering School, it helps a lot to verify my calculations.
But I had an inclined beam and I noticed that the app gets confused with the vertical and perpendicular loads, when I put a vertical load of 1kn/m in a 1 m horizontal span, it throws two vertical reactions of 0.67 kn, I think it´s transforming the load with some angle, but there is no angle. Please verify this, thanks for the app!

### 1/5 — Neads an update

*2014-09-28, version 1.2.1*

It doesn't work on iOS 8
