MTRACK Affretes is a Track & Trace application developed by STEF IT Groupe STEF for sub-contractors' drivers. The app has been updated with new features that allow users to manage pickups, deliveries, and stops. Drivers can now record three real-time schedules - arrival, start, and end of delivery - and take a photo of their global transportation document at the end of the delivery. The app provides immediate feedback to the STEF system.

The new update enables drivers to manage pickups, a feature that was not available earlier, and also allows them to view and consult processed stops. MTRACK Affretes is a free app available on the Android platform and falls under the Travel & Navigation category, specifically Maps & GPS. The privacy policy of the app is available on the STEF website.
