Developing apps in Holland


DTT is one of the outstanding app developers in Holland. One of our key advantages is our experience. We have developed more than 100 apps for different platforms, including iOS, Android, HTML5 and hybrid apps. We have made simple news apps like AjaxFanzone News app and Voetbalprimeur news app, more complex apps like Scoupy app and Doula Labor Coach app and such complicated and profound apps like OSR Starfinder with Augmented Reality and crossplatform game PokerConnect app.  We can develop apps of any level of complexity with any functionality. Apart from functionality we take into serious account user experience and attractive design. 

What differentiates us from our competitors is our strategy towards the clients. We think along with the client, support their ideas and advise them on the matters. Do you have a concept or idea of your app? That's great! But what to do next? How to make your app a success? All these questions better to entrust to a professional, such as DTT. We will help you in devising a technical plan, we will consult you on most difficult questions and we will assist you in forming your idea into a solid concept. It is very important to decide what do you want concrete and how do you want it to fucntion. We will explain the pluses and minuses of each OS and will help you in choosing the right platform for your app - native or hybrid. Furthermore we will provide you with support in promoting your app on the market and in the appropriate positioning of the app. We know exactly how to make your app a success story in media or inside your company.

The strong side of our company is our team. It is not just a loosely chosen number of employees. First of all we carefully select the most promising workers, we put an emphasis on their skills. Their knowledge is what matters. We have senior developers and we have students who also learn new things and dare to try themselves in less serious projects. We strive to raise them to a level of professionals and nourish their dedication to the company. Secondly - we sustain a healthy atmosphere in the company by organising social events, providing employess with time for entertainment and supporting them in their troubles. We try to find an individual approach to each member of our team and make them feel comfortable during their work time. We consider it a very important part of our work and do our best for a company image.

Testimonials from our clients


ING Bank

Stephan Swerissen, Formula Manager Sparen en Beleggen

"We would like to emphasize:

  • Young, enthusiastic, technical and professional employees
  • Quick feedback + Good communication via phone / email 
  • Good at executing a concrete idea"

De Lotto

Fiona Mirrer, Coordinator Marketing Communication

"For our most popular and best-known lottery scratch-card, December Calendar, we came up with the idea to develop a fun game that you can play both on the PC and on your phone. For this, we started looking for a multimedia partner and found DTT. Despite the short timetable, DTT has made a super game: the December Calendar game. This game, starring the penguins from the December Calendar 2014  lottery scratchcards, is based on an existing game and is intended as a free fun bonus. You can't win (money) prizes, but you can get the highest score! Communication was smooth, clear and fast and we could always turn to DTT if we had questions. DTT also thought actively with us on how we could generate more downloads and gave us good advice where necessary. In short, DTT has been an excellent partner. We will certainly continue working with DTT in future."
