Yapp

Yapp enables users to create personalized mobile applications for their events, gatherings and groups. Put simply, it is about designing and building iOS and Android apps.

It makes the most sense for businesses launching or rebuilding an app. They also list Mobile and Mobile Apps, so expect those to show up in the feature set. As a very small company team themselves (1 to 10 people), they tend to serve customers of a similar scale best. Small vendors mean quick answers and real influence on the roadmap, but check who covers support when someone is out.

Yapp is based in New York, New York and around since 2011. More on yapp.us.

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

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