Apps for iPhone - Android - iPad - HTML5


An app built by DTT is guaranteed of a good quality. Our team works hard for a high valued result. We only deliver apps that we are proud of. So our focus is always on the quality. If you come to us to have an app developed, you can choose from different platforms: iPhoneiPadAndroidGames, and HTML5. Native or hybrid, everything is possible. Among our clients are well known companies. We developed Tick bite app for the RIVM, a breakdown assistance app for RSR and a webgame for Lotto’s most famous lottery ticket. 

The Tick bite app informs users about the dangers that poses tick to the human life and the Lyme disease. The app offers multiple functionalities to prevent tick bites, as well as vital information on how to remove ticks and how to check yourself. An example: users can immediately see where ticks are active at the moment. They also see the prediction of a tick activity for the next ten days. It is better to be forearmed, isn't it? This is why users can receive push notifications when ticks are active in their area. Its not easy for everybody to remove ticks themself. This is why the app also offers instructions how to do that. The instructions are e.g. a video or text with images. In the tick diary users can make their own rapport of the bites they had and what were the results of this bite. With this diary the user can go to a doctor when he needs help. So no need to be afraid anymore, this app comes to the rescue! 

If you choose DTT as your app developer you don't need to worry about anything, our motivated team will take everything out of your hands. They will advice and counsel you, for you to make the right choice. Since we are a full service app agency, you can come to us with any issue including concepting, positioning your brand, design, development and even promotion. We have passion for our work. This is why we can realize good projects of high quality. We don’t accept projects if we can’t be sure to deliver a good result. If our possibilities meet your desires, then the first step is to do a proper research. We gather the needed information for an amazing result. 

So what happens next? When the research is done, we continue with making a workflow. This workflow is a functional design of all the screens of the app. Because we find user friendliness important, this is already a very serious part of the workflow. So our critical view is guaranteed. Eventually we reach the state of a final workflow. This is the fundament of your app. This is our key to success.

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."
