Thank you for your interest in the iSPEX project! In this first stage of the project, we will limit our activities to the Netherlands. However, if all goes well, we hope to expand our activities to other European countries. In order to participate, you will need the following:

• An iPhone 4, or 4s. In the future, we hope to include different smartphone models, but we focus on one type of widely used smartphone for now.
• An iSPEX add-on
• The iSPEX app installed on your iPhone.

The iSPEX add-ons have only been distributed on a large scale in the Netherlands and are currently out of stock. If you want to be informed about further developments, follow us on twitter.
