More than 8,000 chefs and other hospitality professionals have downloaded the app through the iTunes store, and will receive a notification on their Apple device when the update is ready.

Managing director John Pinder said: “Like all app providers, we have to adapt when Apple updates its software, but we’re acting quickly to ensure the GP app is fully compatible and displays effectively on the larger screens of the new iPhones.

“With so many chefs and restaurant managers now using the GP calculator app routinely to manage margins and calculate menu prices, ensuring that it stays up-to-date is essential.”

The updated app is expected to be available in the App Store with iOS 8 User Interface updates in early October.

The GP App is the first digital product to receive the Craft Guild of Chefs endorsement, and allows users to manage their menu costs using one of three calculations: by keying  in the cost of ingredients and target percentage GP,  users are given the correct price to charge on the menu; entering the menu price and required margin gives the target cost price for ingredients; and keying in the cost of ingredients and selling price of a dish gives a readout of the gross profit being made.
