Greenpeace: To raise awareness about protecting the Southern Ocean, the habitat of penguins, we created the King Pinguïn AR-app.
Randstad: A Progressive Web App, allowing 36,000 employees worldwide to share their stories and ideas about the Human Forward Approach in various forms, such as: videos, images, and text notes.
By working closely with our clients, we have built expertise across different industries. We have experience in developing:
When developing an app, everything revolves around the user experience. We start with a functional design. This shows all screens, functionalities, and illustrates how the user navigates. At DTT, we strive for top quality and a design that stands out. Discover in which industries we have applied this as well.
Apps come in various forms and sizes. Each app is designed to meet specific needs, using different techniques. Native apps are specifically developed for one operating system, such as iOS or Android. This ensures optimal performance and full access to all device features.
Web apps, on the other hand, are platform-independent and run in the browser, making them easily accessible without installation. Hybrid apps combine the advantages of both: you build one solution that can be deployed on multiple platforms, such as iOS and Android, web, and desktop.
Additionally, there are also Progressive Web Apps (PWAs), which use web technologies to provide an app-like experience, with offline access and push notifications.
The choice of app type and the techniques used depends on the objectives, target audience, and required functionality of the app. Explore the possibilities!
With native iOS apps you make a smart choice for long-term success. Because the apps are specifically developed for Apple devices, they perform optimally and have access to all features of the iPhone, iPad, and Apple Watch. This is crucial for apps that make intensive use of hardware, such as the camera or sensors. Additionally, Apple’s closed ecosystem offers extra security and reliability, which is important for users.
With native Android apps you are assured of a future-proof solution. Since the app is specifically developed for the Android operating system, you benefit from maximum performance. The app has full access to all the smartphone's features, which is essential for apps that use complex extensions. Furthermore, Android offers massive growth opportunities as it has the largest user base globally.
Our approach brings your idea to a compelling app. Step by step, we work together towards an effective solution that really helps you. Solidly designed and future-proof. This way, you stay at the forefront and are assured that your solution will still be running smoothly in a few years.
Concept and strategy: our collaboration begins with a kick-off session where we zoom in on the desired solution and objectives.
Research and design: In co-creation, we combine our knowledge and experience, working together on a solution that aligns with the established goals.
Estimation and planning: we make the investment concrete with a budget based on an open calculation. This helps us create a successful and strong first version within the desired budget.
Start development: Once the budget is approved, development begins. We work together towards the first milestone: a successful launch.

The time it takes for your app to go live in the App Store can vary, depending on various factors. Generally, at DTT, it takes about 2 to 6 months to build an app, depending on the complexity and specifications of the project. After the development phase is complete, a testing and approval process follows, both internally and with Apple (for iOS) and Google (for Android). Submitting to the App Store itself can take anywhere from a few days to weeks, depending on how quickly Apple or Google approves the app. This process can be influenced by the quality of the app, adherence to the App Store guidelines, and any revisions needed after feedback from Apple or Google. In summary, the total timeline can range from a few months for development and a couple of weeks for approval, after which your app will be available to users in the App Store.
Annual maintenance costs are typically around 10-20% of the development budget. Various factors influence maintenance costs, such as the scope of the solution, platforms (iOS, Android, Web), any integrations with other systems, and the level of (proactive) support required.
