Our citizen science apps

For more than ten years we have been creating (citizen-) science apps and platforms for universities, NGO's and other institutions. Here is our portfolio..

The Transit of Venus app

The Venus Transit app was an application that was specifically designed for the Transit of Venus event that occurred on June 5-6, 2012. The app was widely popular and received more than 130,000 downloads in the various app stores, making it one of the most successful citizen science apps at the time.

The app was created by Pocket Science and was used to measure the distance between the Sun and Earth with a high degree of precision. This was achieved by using thousands of volunteers who were able to capture images of the Transit from different locations around the world. These images were then analyzed by the app to calculate the distance between the Sun and Earth.

The Venus Transit app was a groundbreaking initiative as it allowed scientists to collect data from a large number of sources, which would have been impossible to achieve with traditional methods. Additionally, the app also served as an educational tool, allowing people to learn about the Transit of Venus and the science behind it.

The success of the Venus Transit app has inspired other citizen science projects, and it remains a prime example of how technology can be used to advance scientific research and engage the public in the scientific process.

We created the app for astronomers without borders and worked together with ESRI/NASA/Sky & Telescope

The Digital Diversity Wheel app and platform

For Oxfam we created the  Digital Diversity Wheel app. 

A tool designed to promote diversity in agriculture in drought-prone countries like Zimbabwe. The app was developed to support Farmer Field Schools, which are a type of community-based learning where farmers come together to learn about new farming techniques and share their experiences.

The app used a digital wheel to help farmers optimize their crop selection. The wheel allows farmers to select crops based on a variety of factors such as water requirements, resistance to pests, and market demand. By selecting a diverse set of crops, farmers can increase their chances of success even in challenging conditions like drought. The app also provides farmers with detailed information on how to plant, maintain, and harvest the selected crops.

The Digital Diversity Wheel app has been used in rural areas of Zimbabwe and Uganda, and it has helped farmers to improve their crop yields and income. The app has been well-received by farmers, who have reported that it has helped them to make more informed decisions about their crops.

Overall, the Digital Diversity Wheel app is an innovative tool that uses technology to promote sustainable agriculture in drought-prone countries and help farmers to build resilience to climate change.

Arcticmarch

Arctic March - RIVM

The Arctic March app was a special application that was developed in cooperation between the Dutch Environmental Agency (RIVM) and polar researcher Berenice Nootenboom. The app is designed to operate in extreme conditions, such as very low temperatures and in areas with no connectivity.

The app was used in combination with an iSPEX unit, which is a device that measures aerosols in the atmosphere. 

The Arctic March app was designed to be used in remote areas of the Arctic, where traditional methods of data collection may be difficult or impossible. The app's ability to operate in extreme conditions and its ability to collect and store data, even in areas with no connectivity, was a key factor in the success of the research project.

Broncho3

Medical apps

Broncho is an app developed for medical doctors and respiratory specialists at Amsterdam UMC. The app acts as a "traffic guide" through the airways, providing detailed information and images of the respiratory system to help doctors navigate and diagnose respiratory conditions. The app is designed to be used during bronchoscopies, a procedure used to examine the inside of the airways.

The Acute Patient app is another medical app developed for Slotervaartziekenhuis Research. This app is a reference tool that uses smart algorithms to quickly diagnose acute medical conditions. The app is designed to be used in emergency and critical care scenarios, providing doctors with information and guidance on how to diagnose and treat a wide range of conditions.


Labtracker is an innovative web-app developed for Maastricht University Medical Center. The app is designed to help medical professionals track and analyze variations in blood samples over time. It provides a user-friendly interface that allows doctors and lab technicians to easily view and compare test results, and identify any abnormal patterns or trends. We carried out the CE marking for Labtracker.
