Picture yourself as a project manager at Tesla. How would you go about creating the Tesla app for the Apple Watch?

This question aims to evaluate your capacity to create a product that fits within the limitations of a smaller platform (in this case, the Apple Watch) while ensuring that the essential features and functionalities of the primary product (the Tesla car) remain accessible. It's about grasping the user experience to adapt functionalities into a more compact and convenient interface. Here’s a suggested approach: Identify the core features of the Tesla app, such as charging, autopilot, scheduling, and temperature control. Examine the restrictions and capabilities of the Apple Watch—it is compact, touch-operated, wearable, and constantly available to the user. Determine which features would be the most critical or beneficial to have readily accessible on your wrist. Consider the user experience—how can these features be retrieved quickly and effortlessly?

To begin with, I would pinpoint the features that are most frequently utilized in the Tesla app. Likely candidates include charging information, essential vehicle statistics like battery range, and the status of the door locks. Considering the limited screen size of the Apple Watch, it is important to strategically prioritize features and minimize the number of clicks required for a user-friendly experience. The main display could showcase key car status information such as power, range, and whether the doors are locked or unlocked, as these are likely to be the most accessed details. By swiping left, users could access a charging controls screen that enables them to start, stop, schedule charging, or set charging limits. Additionally, the Apple Watch's Force Touch feature could be employed for features that are used less frequently, such as valet mode or adjusting the cabin temperature. To enhance user interaction, haptic feedback could be implemented for notifications, such as when charging is complete, when the car is unlocked, or when the cabin temperature reaches the desired setting. This would serve a dual purpose: keeping the user informed while also capturing their immediate attention.

When designing the Tesla App for the Apple Watch, the key strategy would be to reduce the number of actions a user needs to take on a daily basis. The main display could provide a quick overview of essential metrics, such as battery charge level, remaining estimated range, and the car's lock status. A simple tap on this screen could lock or unlock the vehicle. To make use of vertical space, we could implement a scrolling feature that allows users to scroll down to access and manage additional functions like climate controls, enabling heat or A/C before entering the car. For more advanced features, a Force Touch could reveal options for controlling the lights or activating valet mode. Additionally, integrating Siri would enable voice commands, which is particularly beneficial for hands-free operation. Another possible feature could be the integration of Apple Maps within the Tesla Watch app, helping users locate their car in a parking lot or reminding them where it is parked in an unfamiliar area.
