Smartphone-use coaching and parental controls
A service for parents to review smartphone habits and device status and receive usage-time coaching. I developed the Flutter app and GraphQL server and implemented subscription payments.
Screens
Usage and device status together
Parents can review usage time, app and website restrictions, battery status and location. I connected Google Maps and used GraphQL for communication between the app and server.
App and server development
I connected the parent app’s features to their server-side data handling, including safe-zone departure alerts and subscriptions for service access.
Keeping subscription state connected
Service access must agree across the store, app and server. When payment issues occurred, I examined the client and server flows together.
