CellBreaker

CellBreaker allows to easily switch cell phone carriers. Put simply, it is about designing and building iOS and Android apps.

Who is it for? Mostly businesses launching or rebuilding an app. Related areas on their profile: Mobile and Mobile Apps. They are a small team, 11 to 50 people, which usually shapes who they work with. Small vendors mean quick answers and real influence on the roadmap, but check who covers support when someone is out.

CellBreaker is based in Durham, North Carolina and founded in 2007. You can read more at cellbreaker.com.

Before you commit, look at portfolio quality, app store experience, and maintenance terms. Get the renewal terms in writing before the first invoice.

If you have worked with CellBreaker, tell the next buyer what you paid and what surprised you. That is the part of this page we cannot write.
