Our 7-Step Mobile App Process
1. Discovery & Strategy (Week 1) — Goals, target users, MVP scope, success metrics. Competitive teardown. Technical feasibility. Output: signed PRD + architecture blueprint.
2. UX Research & Wireframing (Week 1-2) — Journey maps, low-fi wireframes, interactive Figma prototypes
3. UI Design & Design System (Week 2-3) — Hi-fi Figma, motion specs, design tokens, dev-ready handoff
4. Architecture & Backend Setup (Week 2-4) — API design, database schema, auth (OAuth 2.0, biometrics, SSO), cloud IaC, CI/CD pipeline
5. Sprint-Based Development (Week 3-10) — Two-week sprints, demos each sprint, code review on every PR, beta builds via TestFlight / Firebase App Distribution
6. Mobile-Specific QA (Week 8-11) — Real-device matrix (BrowserStack / AWS Device Farm), OWASP Mobile Top 10 audit, performance profiling (Instruments + Android Profiler), accessibility (WCAG 2.1 AA, VoiceOver, TalkBack)
7. App Store Submission & Launch (Week 10-12) — App Store Connect / Google Play Console submission, privacy nutrition labels, App Store Optimization (ASO), soft launch in pilot regions, crash monitoring (Sentry / Crashlytics), full rollout
Engagement Models for Mobile Projects
- Fixed-Price App Build — Best for MVPs and well-scoped first-release apps. Locked scope + timeline + price. Milestone payments.
- Dedicated Mobile Team — Best for ongoing product evolution post-launch. iOS dev + Android dev + cross-platform dev + QA + designer + PM as a unit. Monthly billing.
- Hybrid (Fixed for v1, Dedicated for v2+) — Most popular among funded mobile startups. Lock in the launch, scale the team for the roadmap.
Mobile-Specific QA & Testing
- Real-device testing — BrowserStack and AWS Device Farm for 50+ device/OS combinations
- Automated tests — XCTest / XCUITest (iOS), Espresso / JUnit (Android), Detox / Maestro (React Native), Flutter integration tests
- Crash analytics — Sentry, Crashlytics, Bugsnag with pre-launch crash thresholds
- Performance profiling — Instruments (iOS), Android Profiler, frame-rate testing for 60fps/120fps targets
- Battery & memory tests — Profile per session class (idle, background, foreground active)
- Network resilience — Offline-first testing, slow-network simulation (3G/2G), captive portal handling
- Security audit — OWASP Mobile Top 10, jailbreak/root detection, certificate pinning, secure keystore
- Accessibility — VoiceOver (iOS), TalkBack (Android), Dynamic Type support, color contrast (WCAG 2.1 AA)
- App Store pre-flight — Privacy manifest validation, App Privacy details review, age rating verification
Mobile Deployment & Release Cycles
- CI/CD pipelines — GitHub Actions, Bitrise, Codemagic, App Center for mobile-specific builds
- Build artifacts — Signed IPA + APK / AAB with versioning, ProGuard / R8 obfuscation for Android, App Thinning for iOS
