Androidworld

Android World is the largest Android Community. In practice that means designing and building iOS and Android apps.

The natural audience is businesses launching or rebuilding an app. Alongside the main category they mention Communities. 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.

Androidworld is based in Nederland, Texas. More on androidworld.nl.

Things worth asking about: portfolio quality, app store experience, and maintenance terms. Ask for a trial on your own data, not a canned demo.
