We connect citizens with scientists
using mobile technology and powerful data services
We are DDQ. We create and deliver innovative software for almost every mobile platform, everywhere. From the Arctics to Zimbabwe.
Smartphone based citizen science projects
DDQ develops true native citizen science applications with research partners worldwide. We know the capabilities of citizens using smartphones and its sensors. Our apps are featured on the BBC TV, CBS News, Nature and Scientific American.
Flexible back ends, data services and databases
We provide tailor made, flexible and fast smartphone back ends to facilitate mobile cloud computing, user notifications, storage and offline synchronisation for working in remote areas.
Public outreach and education
We share our citizen science knowledge, teach children how to code, talk at TedX and tell everyone about our exciting work.
