Available to Santander customers and non-customers on iOS and Android, the ISA app also allows consumers to find out more about the products and rates available to them ahead of the UK ISA deadline on 5 April 2015.
With the new clean user interface, consumers can view information about ISAs, compare interest rates, and find out the interest rate they can earn through a calculator.
They can use the bright and bold countdown clock to keep track of how far off the ISA deadline is to ensure they maximise their ISA allowance.
The app also consists of details of Santander’s ISA product range allowing customers to open new accounts, upgrade existing ones and make transfers into ISAs.
Monitise’s latest app draws on its design and development capabilities and delivers a simple mobile banking solution.
Santander Savings head Helen Bierton said: "The app will help people to maximise their tax efficient savings and make the most of their hard-earned cash.
"With this year’s ISA deadline fast approaching, now is the time for savers to look to make use of their ISA allowances to ensure they take advantage of the tax-free interest available to them."
Monitise Content president Alistair Crane said: "Mobile is a major factor in a consumer’s choice of brand, and how they feel towards them.
"With Santander putting digital at the heart of its strategy, we are working with the bank to invent services which create new ways of doing things for the benefit of consumers everywhere."
