Harjo Keizer
Advisor innovation healthcare and IT
"We got to know DTT as a nice club to work with, a proactive attitude and thinking along with the client are highly valued. At the start of the collaboration, we went deeper into strategy and concept with DTT, followed by the delivery of a creative strong design with strong gamification elements. Furthermore, their organizational strength and process-oriented approach made us move smoothly and steadily towards a beautiful final delivery."

Ernst Bohlmeijer
Professor of mental health promotion
"DTT has built two Progressive Web Apps for us for our positive psychological training of self-compassion and gratitude. With the beautiful designs we have been able to test the effectiveness of our training courses in scientific research. I have experienced DTT as a pleasant organization to work with in the development of our apps. They are good at thinking along and always adhere perfectly to the agreements. In addition, they respond adequately when necessary. I was happy with the result."

Joost Schriever
Global Director Marketing
"DTT has built us an application that allows us to digitally recreate and set up every Randstad office in the world. This is going to help us tremendously in the global rollout of our new positioning Human Forward. In the tool, furniture, floor covering, wall decoration and other elements can be dragged into the room. At the same time, it calculates the associated investment. We have come to know DTT as very professional, creative, correct and extremely pleasant."

Han van Egmond
Core Manager
"DTT happily surprised us by developing this app, Operation Pure. The game, like Pokémon GO, can be played with Augmented Reality in public spaces. The game is educational, you can play alone, but also with groups against each other. For example, you can add schools and or sports clubs in the app to compete with each other. We think it can make a great contribution to raising awareness of litter among youth. DTT helped us super with the development of the app. They think creatively, come up with solutions and are ready to answer our questions. Together we expressed our intention to further develop the app."
Frequently asked questions about community apps
What are the benefits of having a community app created?
A community app offers numerous benefits, including improved communication and engagement within a group. DTT develops community apps that easily connect members, share information and collaborate. These apps promote interaction through features such as forums, chats and event management. In addition, community apps provide valuable insights through data analytics, which helps improve services and increase member satisfaction. With a user-friendly interface and customized features, a community app creates a close-knit, active and well-informed community.
How can a community app increase my members' engagement?
A community app increases member engagement by facilitating easy communication and interaction. DTT develops apps with features such as forums, chats, and push notifications, giving members instant notification of updates and events. By engaging members through polls, discussions, and shared content, the app creates a sense of community and engagement. In addition, gamification elements and reward systems provide additional motivation for active participation. This keeps members more engaged and involved in the community.
What are the costs of developing a community app?
The cost of developing a community app varies depending on the functionalities, complexity and scope of the project. DTT adopts a transparent approach with modular budgets based on open calculation, making the costs per development technique clear. By working together in co-creation and focusing on core functionalities, DTT ensures cost-effective community app development.
How long does it take to develop a community app?
The development time for a community app depends on several factors, including the complexity of the features and the development process. On average, it takes 3 to 6 months, although there are exceptions.
At DTT, the development process is incremental, starting with concept development and strategy definition, followed by design, development, testing and optimization. By working in two-week sprints and focusing on key functionalities, a community app can be developed within a realistic time frame.
What is the development process for a community app at DTT?
The development process of a community app at DTT is structured and transparent. After a kick-off session to discuss objectives and desired functionalities, DTT goes through a process of concept development, design, development, testing and optimization. This process is supported by regular feedback moments, Agile methodology and use of tools such as JIRA for efficient communication and planning. Read more about our methodology here.
Can DTT integrate existing platforms into a new community app?
Yes, DTT can integrate existing platforms into a new community app. Using APIs and integration techniques, DTT can seamlessly link different systems and platforms. This allows organizations to retain existing systems while adding new functionality to their community app. DTT provides customized advice on the best integration solutions for specific needs and goals.
What are the possibilities for gamification in a community app?
Gamification in a community app offers several opportunities to increase engagement and interaction. Some examples include awarding points and badges for active participation, organizing contests and challenges, and providing leaderboards to compare member performance.
DTT tailors these gamification elements to the specific goals and needs of the community. This provides a suitable and appropriate form of gamification that increases member motivation and engagement, without losing sight of the community's primary goals.
What is the difference between a Minimum Viable Product and a fully developed community app?
A Minimum Viable Product (MVP) is a basic version of a digital solution with the essential functionalities needed to launch and gather feedback from users. A fully developed community app includes all desired functionalities and additional features added after feedback and iterations on the MVP.
DTT recommends an MVP approach to quickly launch a working version of the app, followed by iterative development to further improve the app based on user feedback
