Weekly request: "We want a mobile app." First question: "Why?" If the answer is clear (as we explained in our article on when you need an app), let's get to work. This article is the roadmap from idea to launch.
Phase 1: Discovery — Week 1
Before any code, understand:
- Who's the user? Sales reps? Customers? Managers? Technicians?
- Problem you solve? Not every problem needs an app.
- Core features (MVP): 3-5 features max in v1.
- Platform: iOS, Android, or both?
- Budget and timeline.
Output: signed-off document with all the above.
Phase 2: Design — Weeks 2-3
UX Research
- Interviews with 3-5 actual users.
- Competitor analysis.
- User journey mapping.
Wireframes
Low-fidelity sketches for each screen. Verify:
- Logical flow.
- Minimal steps.
- Clear primary actions.
UI Design (High-Fidelity)
- Brand colors and fonts.
- Clear icons.
- Consistency across screens.
- RTL support for Arabic.
- iOS (Human Interface Guidelines) + Android (Material Design) compliance.
Output: Figma files ready for development.
Phase 3: Development — Weeks 3-6
Tech choice
- Native: Swift for iOS, Kotlin for Android. Best performance, highest cost.
- Cross-Platform: React Native or Flutter. One codebase, near-native performance.
- PWA: Advanced web app. Cheapest, but limited.
For 80% of business apps, Cross-Platform is optimal.
Backend & API
- REST API or GraphQL.
- Auth: JWT, OAuth, Google/Microsoft integration.
- Database: PostgreSQL, MongoDB, etc.
- File storage: S3, Cloudinary.
- Push notifications: Firebase Cloud Messaging (free).
Process
- Sprints (1 week each).
- Code review per feature.
- Unit tests for critical paths.
- CI/CD pipeline.
Phase 4: Testing — Weeks 6-7
Test types
- Functional: every feature works as expected.
- UI: on various screens (iPhone SE to Pro Max, Galaxy S24 to A series).
- Performance: load time, battery, memory.
- Security: OWASP Mobile Top 10.
- Compatibility: iOS and Android versions.
- Beta: with 5-10 real users.
Tools
- TestFlight (iOS) — internal + beta.
- Google Play Console (Android).
- Firebase Test Lab — automated testing on many devices.
- Sentry / Crashlytics — post-launch crash tracking.
Phase 5: Launch — Weeks 7-8
App Store (iOS)
- Apple Developer account ($99/year).
- App Store Connect upload.
- Screenshots (6.7", 6.5", 5.5").
- App Preview video (optional, +25% downloads).
- Description + keywords.
- Privacy policy URL.
- Age rating.
Apple review: 24-48 hours.
Google Play (Android)
- Google Play Developer account ($25 one-time).
- APK or AAB.
- Screenshots (phone + tablet).
- Feature graphic (1024×500).
- Description + translations.
- Privacy policy.
- Content rating questionnaire.
Google review: 24-72 hours.
Post-launch: maintenance
- Monthly updates: bug fixes + improvements.
- Quarterly: new features.
- Annual: compat with new iOS/Android versions.
- Monitoring: Crashlytics + Analytics + reviews.
- User support: respond to reviews.
Real cost
| Type | Cost | Duration |
|---|---|---|
| Simple MVP (PWA) | 30-60K EGP | 4-6 weeks |
| Cross-Platform app | 80-150K EGP | 6-10 weeks |
| Native (one platform) | 100-200K EGP | 8-12 weeks |
| Native (iOS + Android) | 180-350K EGP | 10-16 weeks |
| Enterprise complex | 300K+ EGP | 4-8 months |
Case study: sales rep app
Pharma client, 30 reps, needed an app for:
- View prices and inventory.
- Log orders.
- Track visits (GPS).
- Daily reports.
Tech: Flutter + Laravel backend.
Duration: 7 weeks. Cost: 120K EGP.
Results after 3 months:
- Order entry: 8 min → 2.5 min.
- Order errors: 8% → 1%.
- Daily orders per rep: 12 → 18.
FAQ
Q: Can I build it myself with no-code?
A: For very simple apps (Glide, Adalo), yes. For anything needing ERP/API integration, no-code won't cut it.
Q: Is App Store submission hard?
A: No, but guidelines are strict. 30% of apps get rejected first time (usually for small things like missing privacy policy).
Q: Annual maintenance cost?
A: 15-25% of development cost.
Bottom line
Mobile app development is an investment. Done right, ROI is clear within 6-12 months. Done wrong, you lose money and get no value.
Start with a small MVP, test with real users, then expand. Don't try to do everything from day one.
