DTT: mobile app builder Amsterdam


Since our company is based in Amsterdam, we have gained a lot of international experience. In the past, we have created apps for non-Dutch companies too. We are able to create apps oriented on the international market. Doula, one of our international apps has been downloaded in more than 110 countries.

What will be the process of creating an app or a website? The first phase of creating an app or website consists of creating a rough version of the project. During this phase, other team members will do more research about the market and target audience. We will show you this rough version of the project and discuss the choices we have made (based on our research). We are pleased to hear your comments and feedback. With your feedback, we are able to change the rough version of the project to your liking. After this phase, it is time to create the final product.

Do you have any questions, requests or comments? We will be delighted to help you. You are free to contact us by telephone or email. You are also welcome to visit us in our Amsterdam office at any time. Our team has one simple goal - creating the perfect app or website for you or your company. Mobile app developer DTT is the right company for you.

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."
