Here are three potential topics of discussion for the Hi app and a question for each: 1. **Route Planning** What are your expectations for the app's route navigation and whether it lives up to your expectations? 2. **Offline Maps** Are you concerned about the app's use of online data versus offline maps, and how it affects your navigation experience? 3. **User Interface** How do you think the app's design and user interface compare to other navigation apps you've used, making it more or less user-friendly?
