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: iPhone, iPad, Android, Games, 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.
DTT has extensive experience in developing business apps for both public and in-house distribution. We have developed such apps as ING Marketing day app and BAM Inspiration solution.

So you can be sure about the fact that we will always keep you up to date. We are always available for your questions or comments, before, during and after the development process. We guarantee to provide the best support.
We would like to meet you to discuss your wishes and ideas. We will always be honest to you, that is our promise. If we don’t have faith in your idea, we will tell you.

This will help us tremendously during the worldwide spread of our new positioning Human Forward. Furniture, wall decorations, floors and other elements can be placed into the location with the tool. Simultaneously, a calculation is being made of the coinciding investment.
We have gotten to know DTT as very professional, creative, correct and extraordinarily fun.’’

"Speaking for both myself, Joost and the entire projecteam, I would like to thank DTT deeply for your efforts. We are thrilled with the end result!
When we approached you with the request to make penguins appear everywhere in the Netherlands through AR, we received an exceptional proposal. A very entertaining elaboration of our campaign to make the South Pole a protected marine reserve. Together we quickly came up with the name for the King Penguin app and fun occasions to use the app so everyone can search virtual penguins via AR in their own neighborhood. By combining this quest with information about the animals and their threatened environment at the South Pole, awareness is created in a playful way. And that's exactly what we wanted. Once again, compliments on how fast you brought this amazing app into the digital world. I experienced it as a very pleasant collaboration."

"DTT has helped us twice. First, DTT devised a prototype for an app and when this was well received, they made a fully dynamic version of the app. Our needs and requirements were not easy to fulfill, but during the pleasant co-operation we have come to a good design that satisfied both parties. In the implementation phase DTT came up with good proposals for the app, but also gave us good advice on how we could position our app within the organization. It is amazing how our complex scoring model was so easily implemented, so our non-technical colleagues can manage this through the back end."

"We wanted to create an additional training environment for medical students. On the basis of realistic medical cases, they can learn how to interpret heart and lung sounds. In collaboration with DTT we have developed Clinical Challenge app, so students can easily practice their knowledge.
DTT was a reliable partner; employees think along with you, quickly answer questions and provide qualitative results. Through a good rating system with highscores and attractive animations with sounds, it resulted in a good app. Students are excited about it and are more eager to learn."

"Very recognizable, the description from other organisations about the collaboration with the DTT team.
DTT supported our team during the development of the game concept to a fun and informative app, with which entrepreneurs can learn more about importing in a fun manner. By playing the import missions users will receive direct feedback of their own knowledge level. Via the attained score and ranking, they will challenge their friends to a competition.
DTT created a whole game in a short time. Short communication lines. Clear in expectation management. A lot of patience with our search for the maximum attainability within the proposition. Proficient in the translation of wishes and demands to a practicle solution."

Safety on and around the construction site is an important issue for BAM Utiliteitsbouw and Royal BAM Group. To emphasize this, BAM Utiliteitsbouw has introduced the "BAM builds safe" web app. In co-operation with DTT the web-app was worked on with enthusiasm and realised in a short amount of time. The design and the development of the web-app was a rush order. DTT has delivered a complete and fully operating solution. Our compliments to DTT and their proactive and flexible approach.

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!"

"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."

Ad van Luijt, chairman of the Build@School Foundation
"Since 2015 we are playing a construction game at schools to encourage students to choose for construction technology. This game in which a Lego house has to be built, was supervised by a few game leaders. As it was becoming a problem to find enough game leaders every time, the decision was made to change the game into a digital construction game.
This is how I came in contact with DTT in Amsterdam. After meeting with Jeffrey and his organization, we decided to let DTT build the game.
This has been done to great satisfaction of our Foundation "Build@School". The employees of DTT were always there to process questions and suggestions that we had. The game is being played for a year now and we intend to expand the game further. Of course we would like to do this again with the cooperation of DTT."

"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 .......!? "

"DTT has really done a great job by developing the first KNHS Dressage and riding tests app for iOS and Android. Despite the short development time (and thus high pressure on the project) DTT has taken the usability of the app into account and has given clear advice on functionality and design. Thanks to the pleasant and efficient co-operation, the app could be launched on schedule and within budget. This was well noticed: the app reached the number 1 position in the category 'best paid' in iTunes. The team of DTT is commited, enthusiastic, works fast and communicates clearly. An absolute must!"

The app is now live and our customers are very satisfied with it."

The experience we had with DTT as an app developer is very positive. They have a great ability to quickly and efficiently turn a joint idea into an actual working app. It is a proper challenge to develop a good concept with two independent housing cooperations in Amsterdam, Eigen Haard and The Alliance. With the commitment, expertise and pragmatic hands-on approach, DTT's work is beyond expectation. Through good, direct and precise communication we have created a great product in a very short time.

Since 2012 we have been doing business with DTT to develop our Parkinson Exercises Android app in different languages. We work from a non-profit foundation with charitable objectives and in the beginning we had a lot of budget-friendly solutions. After DTT has converted our first iOS app into Android app, they became our go-to developer for Android versions of our app in multiple languages. The latest French version has a more complex development challenge with an in-app purchase and code access system. DTT has quickly and efficiently implemented it. Employees are flexible, work good and fast and respond promptly to emails and phone calls. Overall, a good company with excellent employees.

As a student association, communicating to your members is very important. Therefore, an application would be very valuable for us.

The commitment to reach deadlines is commendable, work didn't stop even during evenings and nights and quality is simply beyond comparison. For me, DTT has proven to be a very knowledgeable and knowing company. All this gives me the confidence to pick up the phone and call them directly for the next assignment,"

We approached DTT for the development of an internal iPhone app, we knew exactly what we wanted and what the challenges were. Several other app developers promised that they could deliver this app as well, but DTT was the only company that showcased that they could develop this application with the help of a video. This gave us the proof that we we’re talking to the right company, and that is proven! Short reaction times, correct responses to questions and no fuss with minor changes. In short, we will certainly use their services more often.

We decided to build a Mobile application to provide our advertisers with an extra platform and to react on the current consumer demand. For this project we approached DTT. We are very satisfied with the short delivery time that was needed to finish the application. The level of communication was above expectations as well.
