Mobile app developer 

Special about DTT is it’s multi-disciplinary team. Employees of DTT are specialized in: marketing, communication, design and developing the final product: the app. With this team we are experienced as an allround mobile app developer. We develop apps for employees and corporate clients, apps aimed for consumers and game development. This process starts with a concept and ends with the live release of the app in the App Store (iOS) or the Google Play Store (Android). Please check our portfolio for our previous projects. Besides apps, it’s possible to let DTT develop your website. DTT is a flexible and pro-active partner.

Mobile apps for your employees and corporate clients

DTT develops apps for your employees. There are multiple opportunities for apps for your employees. For example, but not limited to: share ideas, have discussions or ask questions. Maybe you would like to post short corporate news? Should everyone read this news or only a select group of employees? An agenda with activities or deadlines in your company? Using E-learning in your own app? The possibilities are endless. With a customized app, your employees always have access to the right information.

Mobile apps for consumers

DTT has developed the RIVM Tick bite awareness app for RIVM, the Fox Sports Camera app and an app for the Valtifest festival. These apps are developed with different objectives, audiences and revenue models. All of this is possible at DTT.

Companies often don’t really know what possibilities their app has. An app is a great way to build a strong relationship with the client. Further on, an app is suitable for supporting other activities from your company. DTT researches what your audience expects from the app and what possibilities they like to see in the app. Using those insights, we develop the right strategy for your app. The strategy is aimed for announcing your app at the audience, to suffice the audience’s expectations and to engage the audience with the app.


Games can be integrated in afore-mentioned solutions. It’s also a possibility to develop a separate game. Games can be developed with different objectives. For example, with an educational aspect, or for amusement. Besides that, games can be integrated in your social media-activities, your online- and offline campagnes or events. A game is a great solution to create more interactivity between you and the consumer.

Web solutions

Apart from app development, we are specialised in web development. We develop websites with a modern design and the latest developments. It’s important the website is user friendly and the user is directed to the right place. DTT takes care of an implementation with Google Analytics. This way, it’s possible to analyse what visitors do, where they are and how they react. This allows for continuous website optimization. We can also help you improving the findability of your website in search engines.

Testimonials from our clients



Desirée Beaujean, Head of Development and Implementation Department

"The RIVM (National Institute for Public Health and Environment) had the "Tick bite" app launched in April 2014. This app was initially developed for Android. With this app people can check what ticks are and how to correctly remove them (even without internet connection!). Starting from July 2014 the app will be available for IOS also.

In the beginning we have spoken with a number of potential executors and we chose for DTT. What struck us was that from the very start DTT was very involved in the issue and the development of the app. The rates were reasonable and certainly played a role in choosing DTT. During our collaboration, we got to know Jeffrey and Dirk better. We emailed and called eachother so often, we even noticed the urge to contact them when it wasn't necessary. I think that says enough!

In short, DTT has been a great partner to develop an app. They are reliable and always up for a joke. Great job!"



Johan G. Gelderblom, Director Finance, Administrative Organisation and Information Technology

"We were looking for a specialist, that could guarantee speed, transparency and quality of service and product and think along with the client! DTT has managed well to deliver the first project, a sales app for our international branches.

We decided to give our second project, a web portal for our international customers, to DTT as well. I am curious whether DTT will manage to succeed here. After all, as they say "You're only as good as your last game", so you have to prove yourself over and over again!

Project 3 (a second Sales app) and project 4 (a complete new website) are still on the drawing board, so .......!? "
