Together with our clients, we get the most out of digital solutions.
A hybrid app can be used for various goals and concepts. Since a hybrid app can be exported to multiple platforms, this development technique is well-suited to serve a broad and diverse audience. As app developers, we are happy to help you determine if a hybrid application is the best fit for your objectives....

National campaign
Innovative campaigning with Augmented Reality
Greenpeace campaigns for the Antarctic Sea, the habitat of penguins. Together, we came up with the innovative concept behind King Penguin AR- in this serious game, you go in search of penguins in your neighbourhood. Here you learn more about the threat to their habitat and can sign the campaign, directly from the app. On April first, this serious game was launched nationally by Greenpeace, resulting in thousands of players and signatures.

Nathalie Zwagerman
Communications consultant Social Media
"DTT contributed to a hassle-free experience for our visitors during the Marine Days by developing the Marinedagen app. In a relatively short timeframe, a fantastic result was achieved. The application ensured that our visitors were properly informed before, during and after the Navy Days. We have come to know DTT as a reliable partner who thinks along in solutions despite the necessary challenges. They are available for questions 24/7. Al in all, a very pleasant cooperation. Thank you for that!"

Joost Schriever
Global Director Marketing
"DTT has built us an application that allows us to digitally recreate and set up every Randstad office in the world. This is going to help us tremendously in the global rollout of our new positioning Human Forward. In the tool, furniture, floor covering, wall decoration and other elements can be dragged into the room. At the same time, it calculates the associated investment. We have come to know DTT as very professional, creative, correct and extremely pleasant."

Marlies P. Schijven
CMIO Ministry of Health, Welfare and Sport.
"DTT has built the “hospital bed checker” for VWS, which allows us to give every healthcare provider a free view of available beds. This is going to help us tremendously also for after the corona crisis. DTT has really done this in record time, I am enormously impressed with the commitment and thinking along in turbulent times. Very professional, well tuned party. Absolutely the right choice!"

Aniek Breevoort
Productmanager
"Since early 2021, Netwerk Mediawijsheid has partnered with DTT for the serious game MediaMasters. In a very short lead time (6 months) DTT has developed a completely new version of MediaMasters including teacher portal, content management system, website and the game environment itself. They did this very competently with an eye for detail and planning. DTT is a party that is good at thinking along with what is needed, acts adequately and is very reliable. They also provide good service on the build and have a high response speed if assistance is needed. We are therefore very pleased with this cooperation."
