Once upon a time all the alerts on the iPhone sounded the same "bleep bleep". With Calalarm we introduced a couple of unique features for a calendar app: own sounds for notifications, nagging alerts and a snooze function. "Can't live without it", our many customers who daily use this app say.

There were also customers who loved the design and user friendliness of Calalarm but did not necessarily need the extra alarm function. For those we developed Supercal.

It was a simple request: if we were able to build an app that could insert holidays into the calendar. It was important that you could decide beforehand which holidays you wanted to add, and after inserting holidays in the calendar you should also be able to remove them. We designed an elegant user-friendly UI and at the end of 2010 we launched the Feestdagen NL app.

It immediately became a hit, within a week we reached #1 position in the Netherlands paid apps. We then developed various holidays apps for other countries and became market leaders in this area.

Cutting-edge image processing. Clictric is able to seamlessly attach two or more group photos from a series.

For the optimal user experience we replaced the traditional photo-editing procedures with layers by an ultra-light UI: a slider bar that enables users to preview their result, in real time! Clictric was a huge success at the Appy Hour of SIGGRAPH 2017.

The NOTO Summary app enables the doctor to make a summary of the conversation with the patient. NOTO Summary already had a first version of this app and asked Devart to build extra features for the recording function. We designed and built a super user-friendly recording module so that doctors can fully concentrate on the texts they record.

FaceMix tests how well you can remember faces. And to what features in a face you pay attention.

FaceMix uses pictures from your photo library or lets you take new photos. The faces are split into six parts and shuffled to form a completely new face, that you have to remember and rebuild. Reconstructing is not as easy as you think. And it's fascinating to see what changing a pair of eyes can do to a face.
