The app called Apprivo is being sold directly to banks and building societies with National Counties being the first mutual to take up the app.
Customers will be able to access their accounts, access up to date product information, transfer money from one account to another and send outstanding information and documents including photos of wage slips and P60s.
Advisers will also be able to use the app to submit information on behalf of clients in the same way.
Barry Yager, director of iState Systems, said: “We really believe that Apprivo and mobile phone technology will permanently alter the way that financial institutions do business and the way that they interact with their customers.
“Apprivo enables banks and building societies to provide their customers with new, highly useable, highly competitive services.
“It means customers can now progress a mortgage, loan or savings account at the touch of a button on their mobile phones; intermediaries will have a new instant-access interface and it reduces the need for documents to be sent in the post enabling banks and building societies to receive them quicker and more accurately.”
