The goal of this project was to utilize the Screentime API (DeviceActivity, ManagedSettings, FamilyControls) to provide users with insights on the apps they use. With the announcement at WWDC22, individual authorization to set shields on apps is now possible, allowing users to have control over their own usage. In this application, authorization is invoked via the AuthorizationCenter in the FamilyControls App Service as soon as the application is launched.
We utilize the SwiftUI framework, which provides a modern and intuitive way to create a
visually pleasing user interface.
We make use of the Device Activity Report Extension to retrieve insights on an individual user's device activity. Each application on the user's device is represented by an ActivityToken, while each category is represented by a CategoryToken. Additionally, Web DomainTokens represent web domains. The insights obtained include:
- Number of notifications per applcation
- Number of pickups per application
- Category for a given application
- Screen time per applciation/category
- The time at which a user had their first device pickup of the day
The FamilyControls App Service allows us to utilize a FamilyActivityPicker, which displays a
list of all the applications, categories, and web domains on a user's device. Users can choose
any number of items from the list, and a viewModel is created to save those selections as a
FamilyActivitySelection. The saved selection enables us to set shields on the chosen items
and lift those shields as well.
The Device Activity Monitor enables us to lift a shield, allowing us to create multiple shield
time intervals instead of a singular option.
This extension allows us to create a custom shield with our logo and personalized message on it.
The Widget Extension allows us to create a custom widget for our application. According to Apple's
guidelines, the widget should provide glanceable information and stay up to date with your application.
Our widget shows whether the user is in restriction mode or not, and displays the time at which their
restriction mode will be lifted (if they are in restriction mode). To enable communication between the
extension and the main app, we created an app group, providing a line of communication between the
widget and the main app.
RiveRuntime enables us to implement an animated navigation bar for seamless navigation throughout our app.
Additionally, it provides a beautifully animated background for our onboarding screen. We chose Rive assets
over Lottie assets due to their smaller size.
We use SwiftUICharts to properly display the data gathered from the Device Activity Report. The charts
are animated, offer various color schemes, and adapt to light and dark mode. Users can interact with
the charts to explore the data.
