Prototype flows
Link these in Figma. Examiners should click through without your voice-over.
Flow 1 · App entry
Flow 2 · Core task (all three features)
Core flow screens: Compare · Results · Provider detail · Corridor saved
Flow 3 · Navigation
Link every nav tab so examiners can tap each bottom nav item. Tabs: Compare · Saved · Learn · Profile
Flow 4 · Unhappy path
Trigger the unhappy path edge case and link to that screen.
Unhappy path
Design this as its own screen state (frame 12):
User enters amount below provider minimum. Show: Minimum send is ₦X equivalent for this provider.
Link in Flow 4.
Design system
- Colour
- You choose. Keep it simple and readable.
- Type
- You choose. Keep body text easy to read on a phone.
- Tone
- Design for your user, not for a tech audience.
Reuse on every screen:
- Primary button (active and disabled states)
- Input field (empty, filled, and error states)
- Card or list item used across the app
- Navigation bar with correct labels and icons
- Empty state: what the screen looks like with no data
Submit & defense
