A method performed through execution of a set of mobile applications for monitoring use of a hygiene product worn by a wearer, which set of mobile applications is formed of a first mobile application and at least a second mobile application, the method comprises the steps of providing information related to the hygiene product based on the voiding behaviour of the product-wearer, and obtaining, by means of the at least a second mobile application, information that is relevant to the voiding behaviour of a wearer, and transmitting the obtained information to a database, wherein the method further comprises the following steps performed through execution of the first mobile application in a mobile device comprising a display for displaying information to a user: - retrieving, from the database shared by a plurality of different mobile applications (A1-A4), stored information that is relevant to the voiding behaviour of the wearer, obtained by means of at least the second mobile application being different than said first mobile application, - obtaining, through said first mobile application, voiding-related information on the actual voiding behaviour of the product-wearer, - comparing the voiding-related information with the information retrieved from the database, - predicting a future voiding behaviour of the product-wearer based on said comparison, and - providing the product-related information related to a change of the hygiene product on the display of the mobile device based on said predicted future voiding behaviour, wherein said first and second mobile applications are different mobile applications selected from a group of mobile applications (A1-A4) consisting of: - a mobile application for obtaining information relevant to the voiding behaviour of a user or voiding-related information on the actual voiding behaviour of the product-wearer by analysing movements of the user, registered by means of a movement sensing device of the mobile device; - a mobile application for obtaining information relevant to the voiding behaviour of a user or voiding-related information on the actual voiding behaviour of the product-wearer through manual input on a mobile device of at least information related to intakes of fluid and/or solid edible material by the user, and information related to voiding of urine and/or faeces by the user; - a mobile application for obtaining information relevant to the voiding behaviour of a user or voiding-related information on the actual voiding behaviour of the product-wearer by analysing images of used absorbent products, captured by an image capturing device of a mobile device, and - a mobile application for obtaining information relevant to the voiding behaviour of a user or voiding-related information on the actual voiding behaviour of the product-wearer by analysing signals received from an odour sensor device capable of detecting chemicals indicative of a presence of urine and/or faeces. - retrieving, from the database shared by a plurality of different mobile applications (A1-A4), stored information that is relevant to the voiding behaviour of the wearer, obtained by means of at least the second mobile application being different than said first mobile application, - obtaining, through said first mobile application, voiding-related information on the actual voiding behaviour of the product-wearer, - comparing the voiding-related information with the information retrieved from the database, - predicting a future voiding behaviour of the product-wearer based on said comparison, and - providing the product-related information related to a change of the hygiene product on the display of the mobile device based on said predicted future voiding behaviour, - a mobile application for obtaining information relevant to the voiding behaviour of a user or voiding-related information on the actual voiding behaviour of the product-wearer by analysing movements of the user, registered by means of a movement sensing device of the mobile device; - a mobile application for obtaining information relevant to the voiding behaviour of a user or voiding-related information on the actual voiding behaviour of the product-wearer through manual input on a mobile device of at least information related to intakes of fluid and/or solid edible material by the user, and information related to voiding of urine and/or faeces by the user; - a mobile application for obtaining information relevant to the voiding behaviour of a user or voiding-related information on the actual voiding behaviour of the product-wearer by analysing images of used absorbent products, captured by an image capturing device of a mobile device, and - a mobile application for obtaining information relevant to the voiding behaviour of a user or voiding-related information on the actual voiding behaviour of the product-wearer by analysing signals received from an odour sensor device capable of detecting chemicals indicative of a presence of urine and/or faeces.
