### 1/5 — Actualización esta horrible

*2023-09-25, version 5.2*

La actualización esta horrible no te da la barra para poner o quitar cosas, arruinaron la aplicacion

### 5/5 — Great app!

*2023-04-06, version 4.2.1*

Great app, very useful for quick SF/BM/deflected shape checks. Has a lot of other functionality too. Would highly recommend for students. Though, it would be great if the option to add a shear connection (pin) between members was implemented - currently it seems you can only use moment connections between members.

### 2/5 — A lot of bugs

*2022-04-01, version 3.7.1*

Every time you try something, it closes

### 1/5 — It is not working properly

*2022-01-20, version 3.7.1*

It closes suddenly. Please, give us support

### 3/5 — Media

*2021-04-09, version 3.6.9*

Se traba a veces y se cierra

### 1/5 — No funciona para estructura nueva

*2020-05-25, version 3.6.7*

No me permite dibujar nuevo pórtico se cuelga 
Solo puedo modificar los tres ejemplo que viene

### 1/5 — Don’t waste your money - doesn’t work

*2020-05-23*

Program does not allow input of members after establishing all nodes. Thumbs down big time!👎🏻👎🏻👎🏻

### 1/5 — Se cierra

*2020-05-16, version 3.6.7*

Pague por ella y he intentado usarla y se me cierra la he probado en dos celulares y no me ha dejado hacer un simple pórtico
No calcula cosas indeterminadas, hay mejores que no cuestan pésima!!!!! Pero pesima!!!!
Perdí 15.000 pesos

### 1/5 — App เด้ง

*2020-04-15, version 3.6.4*

แอพเด้งออกตลอด

### 1/5 — Problem

*2019-11-05*

Can’t pass from the second node.
