Sunsuper Superfund Manager is an iPhone app designed to help Australians manage their superannuation investments and details via their mobile devices. The app provides fast and simple access to your super savings accounts, allowing you to view your super balance with just one touch. You can easily change your personal details, view and nominate preferred beneficiaries, and manage your investments with ease.

One of the app's standout features is its ability to help you stay with Australian Retirement Trust if you change jobs. You can generate a pre-filled form and email it to yourself or your new employer, and get quick access to key information that will assist your new employer in paying your super. Moreover, you can now join Australian Retirement Trust from the app, and get quick access to Rewards for exclusive discounts and offers.

Overall, Sunsuper Superfund Manager is a useful app for anyone looking to manage their super savings accounts on the go. However, you will need to be registered for Member Online before you can access the app. If you're not registered, you can easily do so via the website or by calling the customer service number.
