## Overflow.io Reviews
  ### 1. Good UI, but presentation on mobile doesn't work properly

**Rating:** 0.5/5.0 stars

**Reviewed by:** Shady A. | Full Stack Developer, Small-Business (50 or fewer emp.)

**Reviewed Date:** May 20, 2023

**What do you like best about Overflow.io?**

The UI and flow of work are very good and user-friendly. It was very easy and quick to setup my first project. I would definitely recommend this to a friend if it wasn't for the critical issue I faced when presenting.

**What do you dislike about Overflow.io?**

I eventually threw the project away and stopped using the service because I could not make presentation on mobile fit device width. Which was very disappointing for me. Also support was not responsive or helpful.

**What problems is Overflow.io solving and how is that benefiting you?**

It allows you to easily create flows/wireframes for existing screens to present your work to client/stakeholders.
