What We're Building

Trackener aims at revolutionising equine care with data and technology.
For the moment, daily horse care relies principally on visual assessment and gut feeling, which is very limited. Horse owners and carers are doing their best to take care of the horses but the horses still experience health problems.

Thanks to Trackener Life device worn by the horses 24/7, horse owners and carers can get unprecedented insights on the mobile app about the horses’ free activity, sleep and anxiety, and about the exercise sessions, and get real-time alerts in case of critical problem.
Our device gathers data about all the horse’s movement, activity, location and heart rate. All these data are sent automatically to our cloud and analysed immediately. Trackener Life device can be placed within our ergonomically designed lycra horse bib, comfortable on the horse in the stable and in the field, and on a girth strap for when the horse is being ridden.
