DTT has an experienced team

DTT is an outstanding app development based in Amsterdam. One of our key advantages is our experience. We have developed a lot of successful apps for many platforms including iOS (iPhone & iPad), Android, HTML5 (web). The apps in our portfolio are all very different which show the divergence of our company. We have made simple news apps like the AjaxFanzone News app and the Voetbalprimeur news app, more complex apps like Doula Labor Coach app and the Tickbite Awareness app and some very exceptional apps like the iProvèn E-health app which is a real enrichment for the healthcare sector. 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.

After looking at your concept we will evaluate it, estimate the chances of success and come up with additions if necessary. We take your concept and merge it with everything our team knows about the app development business. We turn ideas into actual products. Once we all agree on a general direction, our team will sort out all the further details. During the whole development process we are giving advices concerning the development of your app. We are literally the whole development process communicating and collaborating with our customers. There are great benefits of this way of working.

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."
