B2B start-up
Exercise classes at 70+ nurseries
Jim Movebooks offers a unique gym class for children: with colourful characters, exercise and play come together. When the Amsterdam studio closed its doors in early 2020, DTT helped transform the Jim Movebooks concept into a scalable B2B solution. In less than 12 months, this Amsterdam start-up rapidly grew to 70+ connected nurseries.
Loyalty app
Belgium's largest garden center, now also as an app
Garden center Famiflora, for garden, deco and animal, is a household name in Belgium. To serve its loyal customers even better, we worked with Famiflora to create its own loyalty app. For every euro spent, users save two Famiflora loyalty points. They can redeem these for discount coupons or other fun rewards. Furthermore, the app offers convenient features while shopping, such as a barcode scanner. The loyalty app solution enables Famiflora to gather valuable insights and further enrich the shopping experience for its most loyal customers.

"Our beautiful Hebban Books App was built by DTT in Amsterdam. A partnership we are still super happy with."
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."
Andries Takke
Director Takke Breukelen B.V.
"We at RTRI are incredibly satisfied with the app developed by DTT. Everything has been thought of. Moreover, a very complex caching mechanism was used, because a lot of data is loaded into the app (over time). A clever piece of work, in which we experienced a very fine cooperation."
Mustafa Demirayak
Project lead
"After working with DTT for 2 years, the end result was very positive. DTT is still working on the new developments for our company app. The new app helps our employees work faster, more efficiently and effectively. Great to see that everything within our company is completely automated, thanks to the thinking team at DTT. Doing Things Together."
Community and gamification
The fair word game - a hit in the app stores
WordCrex puts a unique twist on Scrabble: namely, everyone plays with the same letters. This multiplayer game is wildly popular with a growing community of regular players. Our partnership with WordCrex kicked off in 2022 with a code review and effective optimizations. This resulted in great results and milestones, including 300,000 downloads.

Frequently asked questions about creating iOS apps
What does it cost to have an iOS app made?
The cost of an iOS app depends on the specifications, the desired functionality and the scope of the project. A basic app is usually more affordable than an app with complex functionalities. Contact us for a tailor-made quote.
How long does it take to develop an iOS app?
Developing an iOS app takes between 2 and 6 months on average, depending on several factors. The size of the app, the complexity of the functionalities and the available resources play an important role. By working well together and setting priorities, we ensure that the development process runs efficiently and appropriately.
Can my iOS app be extended later with new features?
Yes, we build your app so that it can be extended in the future. This makes it possible to add new features without having to rebuild the base.
Do I have full control over my iOS app after delivery?
Absolutely. After delivery, you get full access to your app and its source code, without vendor lock-in. This means you can fully manage, modify and further develop the app as you wish.
Will my iOS app be placed on the App Store?
Yes, we guide you through the whole process, including submitting your app to the Apple App Store. We make sure your app complies with Apple's guidelines and is ready for publication.
