The app has been available in most parts of the UK since it launched in September last year.
It has now rolled out even further with Britons in Northern Ireland able to benefit from the perks for the first time.
Head of Sales Operations Lidl Northern Ireland Gordon Cruikshanks said: “We’re delighted to roll out the Lidl Plus app across Northern Ireland.
“As the region’s fastest-growing supermarket, we welcome more than 350,000 customers through our doors each week who visit us for our great quality, low price produce.
“Value is an incredibly important factor for customers which our own research confirms, with half of all consumers heavily guided by low prices, particularly given the financial pressures placed on families over the last 12 months.
“We’re thrilled to now offer our customers even more value and bring additional savings and incredible discounts across our wide range of quality products with Lidl Plus.
The app has also introduced a new feature called Plus prizes so there are even more savings to be had.
Through this, customers can spin a wheel when they shop in the hopes of winning even more.
The top prize is an impressive £20 off for customers to use on their next shop.
Users can also benefit from partner offers where they get discounts on other retailers.
