- Platform
- Mobile app · Android-first · portrait
- Screens
- 11 screens + 1 unhappy path (12 frames)

Build order: Auth (screens 1–4) → nav tabs (5–8) → core flow (9–11) → unhappy path → link prototypes.
Problem & primary user
Personal safety during travel matters nationwide. US has Find My; Nigerian families use phone calls that stop if something goes wrong.
Primary user
"Precious, a 25-year-old banker in Port Harcourt who travels home late."
Geographic scope: National-level
Goals
User goal: Share live trip with a trusted contact until she marks arrived.
Business goal: Freemium family plans; corporate safety packages for shift workers.
Success: User starts trip and marks arrived safely.
Market context
- Question
- Answer
- Who pays
- Family subscription; corporate plans for shift workers.
- Why not WhatsApp
- Family calls every 30 minutes during travel. Stops if phone dies.
- Design focus
- Start trip, trusted contact sees progress, one-tap arrived. Not emergency services.
Competitors to check:
- Phone calls (default)
- WhatsApp live location (manual share)
- Find My (Apple ecosystem only)
Validate before you design
Interview 3–5 people who match your primary user. Update this brief if interviews contradict it. Do not start hi-fi until you complete the confirmation below.
- Validated user (name, age, city)
- Problem in one sentence
- One interview quote
- Success metric for your test
- Primary colour and tone
- One competitor you checked
Interview prompts
- "Walk me through the last time this happened."
- "What did you use instead? WhatsApp, paper, or nothing?"
- "What would make you trust this on a cheap Android phone?"
- "What would stop you from using this every week?"
Features & scope

Screens
Design every row in wireframe, high-fidelity UI, and prototype (where the flow applies).
| # | Layer | Screen | What to show |
|---|---|---|---|
| 1 | Auth | Splash Screen | App logo, name, and tagline for Safe Route Share. |
| 2 | Auth | Onboarding (1 screen) | Explain the app in one sentence. One Get Started button. |
| 3 | Auth | Sign Up Screen | Name, phone number, state, and PIN. No email required. |
| 4 | Auth | Sign In Screen | Phone number and PIN. Forgot PIN link. |
| 5 | App shell | Trip (tab) | Start Trip button, active trip map, or recent trip summary. Show bottom nav with Trip active. |
| 6 | App shell | Contacts (tab) | Trusted contacts list. Add contact button. Show bottom nav with Contacts active. |
| 7 | App shell | History (tab) | Past trips with date, destination, and arrived status. Show bottom nav with History active. |
| 8 | App shell | Profile (tab) | Name, phone, default contact, and safety disclaimer. Show bottom nav with Profile active. |
| 9 | Core flow | Trip · Live share | Map with moving pin and Need help button. Show bottom nav on post-sign-in screens. |
| 10 | Core flow | Trip · Arrived | Arrived safely message sent to contact. Show bottom nav on post-sign-in screens. |
| 11 | Core flow | Contact · Added | Trusted contact saved on Contacts tab. Show bottom nav on post-sign-in screens. |
Layers: Auth = 1–4 · App shell = 5–8 · Core flow = 9–11
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: Trip · Live share · Trip · Arrived · Contact · Added
Flow 3 · Navigation
Link every nav tab so examiners can tap each bottom nav item. Tabs: Trip · Contacts · History · 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):
GPS signal lost mid-trip. Show: Location paused. Last seen at [time]. Trip still active.
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
Deliverables
| # | Deliverable | What good looks like |
|---|---|---|
| 1 | Wireframes | Every screen in this brief, plus the unhappy path. Layout and labels clear. |
| 2 | High-fidelity UI | Same frames polished. You choose colour and type. Bottom nav on every post-sign-in screen. |
| 3 | Prototype | Four linked flows (entry, core task, navigation, unhappy path). Examiners can use the app without your voice-over. |
| 4 | AI prototype | Figma Make: at least 2 screens. Share link. |
| 5 | Case study (1 page) | Problem · User · Who pays · Competitors · Solution · One design decision |
| 6 | Presentation (6–8 slides) | Name · Problem · User · Solution · Key screens · Flow demo · One decision |
