## Most critical reviews (3 lowest-rated)

### 5/5 — Amazing addition to my construction company

*2026-06-06*

Great app for contractors truly saves time

### 5/5 — Must have app for remodeling and building contractors.

*2026-05-16*

This app completely transformed my workflow. Besides its 3d and estimate tools It keeps leads, plans, project profits, and all in-and-out finances perfectly organized in one single place. It’s literally an office in your pocket, and having all my records safely saved forever is exactly what I needed. Highly recommend to any contractor trying to scale.

### 5/5 — Very useful app

*2026-04-05*

I’m a contractor, I’ve been making estimates for 10 years, I used to make everything by myself, sometimes takes me about one entire day to have a estimate ready, with this app, just take me minutes. Have a lot of options that you also can customize, their customer service is also 5 stars. I highly recommend this app.
