Mobile App Design Basic 5 — Questions and Answers
Question 1: What is 'user flow' in mobile app design?
- The speed at which data moves through the app
- A visual map of the steps a user takes to complete a specific task within the app (Correct answer)
- The number of users currently using the app simultaneously
- An analytics report showing user drop-off rates
Correct answer: A visual map of the steps a user takes to complete a specific task within the app
A user flow diagrams the path a user follows from entry point through all screens to achieve a goal, like completing a purchase.
Question 2: Which of the following is a key characteristic of a 'native' mobile app?
- It runs inside a web browser on the device
- It is built with platform-specific languages and APIs, offering full access to device hardware (Correct answer)
- It uses a single codebase deployed to all platforms
- It does not require installation from an app store
Correct answer: It is built with platform-specific languages and APIs, offering full access to device hardware
Native apps are built using platform-specific tools (Swift/Objective-C for iOS, Kotlin/Java for Android) and have direct access to all device features.
Question 3: What does 'card-based UI' help designers achieve in mobile apps?
- Displaying payment information securely
- Grouping related pieces of information into visually distinct, scannable containers (Correct answer)
- Creating flashcard-style quiz interactions
- Organizing app navigation into swipeable sections
Correct answer: Grouping related pieces of information into visually distinct, scannable containers
Cards act as containers that group related content and actions, making complex information easy to scan and interact with.
Question 4: What is the purpose of 'user personas' in the mobile app design process?
- Defining the app's brand personality and voice
- Creating fictional representations of target users to guide design decisions (Correct answer)
- Building user accounts for beta testing
- Documenting the app's technical requirements
Correct answer: Creating fictional representations of target users to guide design decisions
Personas are archetypal user profiles based on research that help designers empathize with and design for real user needs and behaviors.
Question 5: In mobile typography, what is the recommended minimum font size for body text to maintain legibility?
- 8sp
- 11sp (Correct answer)
- 16sp
- 24sp
Correct answer: 11sp
Most mobile design guidelines recommend a minimum of 11sp–12sp for body text to ensure comfortable reading without requiring zoom.
Question 6: What is 'gestural navigation' in modern mobile app design?
- Using voice commands to navigate the app
- Controlling app navigation through swipe and gesture inputs rather than physical buttons or on-screen nav bars (Correct answer)
- A feature that guides users with animated arrows
- Accessibility navigation designed for gesture-impaired users
Correct answer: Controlling app navigation through swipe and gesture inputs rather than physical buttons or on-screen nav bars
Gestural navigation replaces traditional hardware buttons with swipe gestures, as seen in iOS and Android's gesture-based navigation modes.
Question 7: What is the main advantage of using a 'tab bar' over a 'hamburger menu' in mobile app navigation?
- Tab bars save more screen space for content
- Tab bars keep all navigation options visible, reducing the discoverability problem of hidden menus (Correct answer)
- Tab bars support more navigation destinations than hamburger menus
- Tab bars are easier to implement technically
Correct answer: Tab bars keep all navigation options visible, reducing the discoverability problem of hidden menus
Because tab bar options are always visible, users are more likely to discover and use all navigation sections compared to items hidden behind a hamburger icon.
