App development policy in DTT:


Apps become extremely popular in our world of digital information and wide use of smartphones. To have an app for your business can facilitate a lof of business processes in your company, attract additional clients, stimulate interest in your products or services, improve internal communication. App also sheds a positive light on your image and creates a positive attitude in the reputation of the company. We don't think there is a need to continue praising all the advantages of having an app for your business, because we think that the best proove for it are our works. For a whole list of the apps that we developed - check our portfolio.

The process of app development requires professional approach and serious commitment. That's why we advise you to bring your app ideas and thoughts to DTT and entrust us the rest. Our team knows exactly what to do to make your app idea into a sucessful app in the app store. We have already developed more than 100 apps from simple news apps to apps with Augmented Reality and complex internal solutions. 

Our policy purports open communication and compete transparency during the whole development process. The first step towards your app actualization is making important decisions such as type of application. It can be a hybrid or native application, to understand the difference between those 2 types, please read the following article. Then - the platform, will it be a multiplatform app or just an app for a single platform. Recently we have developed a Poker Connect Game - a cross platform game that can be played from Android and iOS devices simultaneously. This is a very smart and inventive decision! Thus we can adapt to your needs and create an application suitable for your goals. 

One of the pronciples of our work is - creating a steady solid relationship with the client. We don't aim for quick wins, our reputation and client satisfaction are of major importance. That's why we take only those tasks that are in our competency. Of course our team always strives to broaden their knowledge and improve professional skills. We have creative designers, goal-oriented developers, diligent project managers and cooperative market managers. With combined efforts we can make your app a success story.

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."
