At Tregony School, we use a new, free, smartphone app for parents called 'School Gateway'. 
You are able to pay for clubs, school dinners, wrap around care, school trips etc through this app. It is also used to keep you up to date with letters and important information.
It is now available for download for Apple (iOS 8 on the iPhone 4S or later, iPad, iPod Touch) and Android (4.0 / Ice Cream Sandwich or later) devices.
