Mobile users will provide personal data streams to more than 100 mobile apps and services a day by 2017, research firm Gartner has predicted.
Gartner found that by 2017, more than £46bn ($77bn) worth of apps will be downloaded, making apps one of the most popular computing tools across the globe.

Apps are often used to push brands towards customers to force engagement. This is especially true of free-to-download apps, which account for 92% of app downloads, as they often include advertising or in-app purchasing.
The current surge in wearable technology will also contribute to app downloads and app-transferred data due to wearable technology often lacking its own user interface. Gartner predicts that by 2017, wearable devices will make up 50% of total app interactions.
Brian Blau, research director at Gartner, said: "In the next three to four years, apps will no longer be simply confined to smartphones and tablets, but will impact a wider set of devices, from home appliances to cars and wearable devices.
"While wearable devices will not fully rely on, or be a slave to, mobile devices, it is a way for manufacturers to keep these devices small and efficient, therefore significantly reducing device costs in favour of using apps, which are more easily maintained and updated," he said.
"Apps are an obvious and convenient platform to enable great products and services to be developed."

App data is often used for cognizant computing, through which data collected about a user, including location, demographic and habits, can be used to adapt the performance of a service.
A recent survey by the Information Systems Audit and Control Association (Isaca) revealed that only 4% of UK consumers consider the makers of their mobile phone apps as the entity they most trust with their personal data
Gartner predicts that by 2015, cognizant computing will have grown to the extent that will fuel future technologies such as smart homes, with firms such as Google, Amazon and Facebook making a headstart in the market due to the large amount of data they already hold on consumers and the level of trust consumers have in them.
