What We Do


We love building mobile applications and web services. We have developed promotional apps to support brands, functional apps to ease lives and business-to-business services to increase process efficiency. Here are some of our recent projects.

Downdetector | iOS, Android

  • Platform: iOS, Android
  • Technology: xCode

The Downdetector service offers real-time status and uptime monitoring for hundreds of services, including telecommunication outages, online banking problems, websites that go down and apps that aren’t working.

Downdetector outage detection is based on a real-time analysis of user reports from multiple sources, including social media such as Twitter, the Downdetector website and reports filed through the app. The service monitors over 2,700 services in 25 countries.

Our assignment for this project was to re-build an existing multilingual iOS application improving the design and adding new features such as in-app purchases.

  • Platform: iOS, Android, SET-TOP BOX
  • Technology: xCode, Java, Airplay and Chromecast, JAVASCRIPT ON METROLOGICAL SDK

Impasto brings masterpieces from the finest museums directly to TV screens.

Now everyone can enhance his living room, office, lobby, restaurant or any other room with beautiful art: the app has over 100 000 masterpieces from the collections of the Rijksmuseum (the Netherlands) and J.Paul Getty Museum (USA).

We have built iOS and Android Chromecast and AirPlay enabled apps as well as a backend to host the images.

Nieuwsbite | iOS, Android, Web

  • PLATFORMS: iOS, Android, Web
  • Technology: xCode, Java, PHP, AngularJS

Nieuwsbite is a digital platform that brings news in an engaging way. It offers a simple and quick way to get involved with what’s happening in the Netherlands and around the world.

The YipiY editorial team (the publisher) selects 10 important news items per day, and offers users a chance to state their opinion about them. Once participants have voted, they will see the statistics of what the rest of the Netherlands thinks about the matter. Next to it users can share their votes via Facebook and Twitter.

A new article appears every two hours and a meter at the top keeps tracking the ‘news knowledge’ of the participant. There is also a coffee break – a funny video – that accompanies each article.

We have built iOS and Android apps, a front- and backend and a highly available infrastructure.

Bébéboek | iOS, Android

  • PLATFORMS: iOS, Android, CMS
  • Technology: XCode, Java, PHP

Superunie wished to draw more attention to the assortment of their Bonbébé baby products. The company went for an app as a log book where mothers could collect pictures of those precious moments.

In the Bébéboek app photos were stored, shared, edited and added to a photo album. Mothers could also keep records of their baby’s height and weight which were plotted in the growth graphics and added to a photo album. The last one was then sent as a PDF per e-mail and could be ordered for printing.

We have built iOS and Android apps, a highly available infrastructure and a notification and synchronization servers.
