"Our task had an absurd deadline, scope-creep all over the place and a fixed price. DTT made it happen. With these stressful conditions, DTT has made a product we are extremely pleased with. 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,"

"Together with DTT we have developed a native iOS and Android app for our b2b customers. With this app they can respond to assignments that individuals have placed on our Kluscontact.nl platform. We developed an API ourselves that communicates with the app.
At DTT they always fulfil their promises. Beforehand they clearly informed and advised us about various options related to native or non-native app. They also took into consideration all interactions and potential complexities that come with these options. The app is now live and our customers are very satisfied with it."

Patrick Özer, Senior Manager Forensic Technology
"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."
Karin Kramer, Online Communications adviser
"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!"

Mary Dankbaar, Program manager E-Learning
"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."

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. Recommended.

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.

We have talked to a number of software developers and chose DTT. What distinguishes DTT from other developers is that they are very involved in the work they are doing and they give an honest opinion when necessary. This continued throughout the whole development process. Issues and questions were rapidly processed. After few discussions, meetings and email communication DTT has made a road map for the development of our business idea for the web, tablet and smartphones. Phase 1 of our responsive website was delivered on time, within budget. We found DTT to be a sincere, creative and collaborative partner who treats its clients in a very friendly and personal way!

"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."

"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 .......!? "
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!"

We were looking for a suitable partner for developing an app and soon found out about DTT. After the first phone call we got a clear picture about the various ways to develop an app and the pros and cons of these options. The offer was clear and good in terms of pricing.

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.

Roos de Jong, Board Member
As a student association, communicating to your members is very important. Therefore, an application would be very valuable for us. DTT had carefully discussed the possibilities and use of the application with us. Jeffrey was very helpful, and I always received answers to my questions and demands. We, as medical faculty association of Nijmegen, are very proud of our application!
Thomas Detailleur, Owner
After some brainstorming on our app idea we had to find a suitable partner to develop it. We searched in google and came across DTT. I sent an e-mail to Jeffrey van Dijk with some discussion points and to my surprise I got a response from him within 15 minutes! It was on a Sunday! That was a positive note from the very beginning. During our co-operation the feedback was always very fast, the problems and questions were treated in a quickly. We found DTT to be a sincere, creative and collaborative partner who treats her clients in a friendly and personal way!

Danny Geveling, Owner
DTT went to the fullest extent to creat a good app. I appreciated their sincerity and professionalism highly. Questions are answered quickly, and I had the feeling of a complete engagement in the project. The "What you Doing?" app is our first app, and I can say without a doubt that we wouldn't have succeeded without DTT. DTT is not afraid to take responsibility and has helped me enormously with everything concerning the app. From creating it to putting it on the app market. To finish with a good slogan, I can say one thing. "Choose DTT because DTT does and thinks along with you!

My young company has experienced a noticeable progress after the delivery of the well designed site. We achieved a high-quality result! Judging from the positive reactions from the customers, we can be proud of our work. Our co-operation resulted in a catchy website and it's a pleasure to the eyes! The number of visitors regularly go over 100 per day. We also see this in the number of new clients who visit our garage. Comparing with the old website, the new one is a noticeable difference. It was more than a worthy investment.

Berry Morre, Owner
A reorganization and an outdated website made us decide to develop a new website. My business partner Reduan, of Knibbe Lettering, told me about his positive experience with DTT. After the first appointment with Jeffrey van Dijk from DTT, we quickly got the ball rolling. DTT has taken care of all the work. The design, copywriting and project management - all this was handled by DTT. In short, I am very satisfied with the preparation and service level from DTT. I get positive reactions to the new website almost every day. The new website is also well visible on my iPad; this is a valuable support during conversations with prospects and clients.

Michele Stigter, Owner
Jeffrey and his team picked up the project when a previous developer backed out of the project because the development of this iPad required a tremendous amount of work. The DTT team provided me with a good support in the development of my concept. It is an app for elementary school children, which combines many elements together. It offers children the curriculum of primary school in a visual form. An excellent co-operation and a good result!
Ben Patelski, Owner

Bart Willemse, Owner
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.
Reduan Bakkali, Owner
Knibbe is a long-held professional company in producing letterings, signs and all forms of visual communication. Of course, we couldn't do without a website that would vividly demonstrate what we do and who we are. For this challenge, we have asked DTT to create a website that would be easily found on the internet and the visitors could find what they need. DTT has expertly, quickly and professionally completed this task. I think that DTT is distinguished by its speed, good feedback and especially the way of thinking during the process. We are extremely pleased with the end product. Our site is constantly developing, since we have realized that web environment never stands still.
Henk de Vreugd, General Manager

4Sight develops Virtual Reality for the urban planning industry. Thus we support and advise governments and developers in marketing their plans. With visualizations you can create more understanding, trust and support for the property development and infrastructure projects. We have asked DTT to extend our pallet of visualization products by an iPad application for infrastructure projects. Besides the very pleasant and open collaboration, DTT offers a quality product, with fast delivery terms at a very competitive rate. Multiple suppliers are able to deliver quality, but next to that, commitment and customer orientation in favor of the client is a second nature for DTT!
Arnold Gruppen, Owner
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. In fact, they chased us more, than we needed to chase them to finish this project :) The result is very pleasing. Next to that, the after sales service was just great.
