Everyday web apps
A browser app can manage a ledger, schedule, quiz or checklist. Choose local or shared data deliberately.
Follow the steps
- Choose the task: track expenses, collect requests, answer a quiz or maintain a checklist.
- Ask for input fields, validation, useful output and the correct storage scope.
- Enter a known example, reload and verify that the intended records remain.
Check your result
One browser’s local storage is not a shared database. Test with a second authorized session when records must be shared.
