### 1/5 — Hips only

*2025-09-04*

Only hip roofs ???

### 1/5 — very basic and difficult to use

*2024-08-25*

i had a trial version of this and is was not very intuative, it didnt give me options to change the type of roof i wanted.  the web app didnt work on my mac either so i had to try to use it on my phone.

i build roofs for a living and thought this might give me a head start before getting to the job however it is needs much alot of improvement to justify paying for it.

### 1/5 — Does NOT save your work

*2024-03-02*

This app is not worth the time! And they charge you immediately and make you create an account before even checking out the app. I highly recommend to stay away from this app until they make it user-friendly. Extremely limited tools.
