### 1/5 — Misleading

*2025-12-15*

Terrible app, terrible to navigate, not at all what I thought it’d be and there’s no way to figure that out until you commit to paying for it.

### 1/5 — Garbage

*2025-07-17*

Worst calculating app ever made! You will need another calculator to convert all your measurements. You can not put in fractions. And you basically need all your information that are trying to achieve to possibly get a solution that isn't needed. Terrible app. Do not download.

### 1/5 — Asked for payment after typing in one number

*2024-10-31*

Would not advise to even try downloading unless you want to pay money for the app

### 1/5 — Not great

*2024-10-10*

Very basic , not worth the money.

### 1/5 — App Needs work

*2024-04-06*

This app needs work. Need to be able to change all feeds. Trying to find proper ridge height to pitch of roof and app keep's telling the wrong joint length. I don’t need it to keep adjusting my figures. I know what pitch I need just trying to find what ridge height I need. 
Don’t pay for this app it useless.

### 1/5 — Waste of time

*2023-07-25*

Not a free app so don’t bother downloading unless you wanna pay
