Gravity Jack

Gravity Jack is a custom software development company offering mobile AR software for the iPhone, iPad, and Android operating systems. Put simply, it is about designing and building iOS and Android apps.

The natural audience is businesses launching or rebuilding an app. They also list Android, Augmented Reality, Computer Vision, iOS and Mobile, so expect those to show up in the feature set. They are a small team, 11 to 50 people, which usually shapes who they work with. You will probably talk to the people who build it, which is great until you need 24/7 support.

Gravity Jack is based in Liberty Lake, Washington. You can read more at gravityjack.com.
