A city simulation game meets an expense tracking app: As the Mayor of Fortune City, keep your citizens happy by recording your day-to-day spending in order to create a growing, prosperous city. Users record their spending in categories such as food, transport, entertainment, and shopping. As they use the app, they can construct buildings and transportation, assign jobs to each citizen, complete missions throughout the city, and do more activities to help Fortune City thrive. The app also provides easy-to-read charts to help users see where their money goes on a weekly, monthly, and seasonal basis. Users can also set goals and earn awards for achieving them. For tutorials on how to use the app, readers should click "Support" at the top of the page and navigate to the "New Mayor Crash Course" section. The app is free in the App Store and Google Play Store, with optional in-app purchases and a premium subscription to unlock extra features such as detailed expense tracking and analyses.
