2. Sydney Travel Guide
It’s nice to know that some of the best city guide apps are free. Triposo’s app allows you to plan your trip around Sydney in advance. It allows you to see the places that you may visit, and plan a route through the city. You can also download your maps so that you can store them on your phone as you wish. There are reviews of places to see and visit, and it contains some really interesting historical and background information about the city.
