Together with our clients, we get the most out of digital solutions.
Do you have an app idea you'd like to launch in the short term? Then a Flutter app might be the solution. Flutter is a hybrid app development platform developed by Google. With it, we can develop apps for both Android and iOS at lightning speed, without writing separate specific code for each platform.

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!"

Han van Egmond
Core Manager
"DTT happily surprised us by developing this app, Operation Pure. The game, like Pokémon GO, can be played with Augmented Reality in public spaces. The game is educational, you can play alone, but also with groups against each other. For example, you can add schools and or sports clubs in the app to compete with each other. We think it can make a great contribution to raising awareness of litter among youth. DTT helped us super with the development of the app. They think creatively, come up with solutions and are ready to answer our questions. Together we expressed our intention to further develop the app."

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."

Irma Evenhuis
Project coordinator
"We put a “dream scan” on paper with all our wishes and those of our users. Together with DTT, we translated this into a design, which was then built. DTT managed to translate our wishes into a beautiful tool. The new Canteen Scan is a visually modern, attractive and user-friendly web app."
