MyTiqs
Ticketing & Event Management Application
Table of Contents
Executive Summary
MyTiqs v2.8.4 demonstrates strong event discovery and a polished QR ticketing experience, but critical issues in security and performance must be addressed before scaling to high-traffic events. The app suffers from exposed payment gateway credentials, excessive memory consumption during QR scanning, and a ticket purchase flow that loses over a third of potential buyers at registration. Immediate remediation of the 5 critical findings is strongly recommended before the next major event season.
Overall Scores
| Category | Score | Rating | Visual |
|---|---|---|---|
| Overall | 72/100 | Needs Work | |
| Performance | 68/100 | Critical | |
| UX / Design | 82/100 | Good | |
| Security | 58/100 | Critical | |
| Code Quality | 78/100 | Acceptable |
Key Highlights
- Excellent QR code scanning performance with real-time ticket validation under 0.3s
- Clean event categorization and discovery UX with intuitive filters and modern Flutter architecture
- Critical: Payment gateway API keys and Stripe test credentials exposed in client-side code — immediate action required
- Critical: App cold start time exceeds 4.2s on mid-range devices — at event venues with thousands of users, this causes severe entry bottlenecks
Performance Analysis
68/100| Metric | Current | Benchmark | Status |
|---|---|---|---|
| Cold Start Time | 4.2s | < 2s | Critical |
| Hot Start Time | 1.8s | < 1s | Warning |
| Frame Rate (avg) | 52 fps | 60 fps | Warning |
| Memory Usage (idle) | 245 MB | < 150 MB | Critical |
| Memory Usage (active) | 380 MB | < 250 MB | Critical |
| Network Payload (home) | 2.8 MB | < 500 KB | Critical |
| App Size (iOS) | 89 MB | < 50 MB | Warning |
| App Size (Android) | 72 MB | < 40 MB | Warning |
| Battery Drain (1hr) | 12% | < 5% | Warning |
| Crash Rate | 2.3% | < 1% | Warning |
2.1 Performance Recommendations
- 1.Implement lazy loading for event banners and venue images — current eager loading is the primary cause of the 2.8 MB event listing payload
- 2.Reduce cold start time by deferring non-critical SDK initialization (analytics, crash reporting) to post-first-frame — critical for venue entry scenarios
- 3.Profile and fix memory leaks in the QR scanner module — 380 MB active usage suggests camera stream not being properly disposed after scan
- 4.Enable Android App Bundle and iOS App Thinning to reduce download sizes by ~40% — essential for on-site installations at events
- 5.Optimize event list rendering with pagination — currently loading all 500+ events into memory at once, causing jank on scroll
UX & Design Review
82/1003.1 Onboarding Flow
GoodClean 3-step onboarding with skip option. Illustrations are engaging and load quickly. Consider adding progress indicators.
3.2 Search Experience
WarningEvent search lacks auto-suggestions, date-range filtering, and location-based sorting. Users must type complete event names. No "nearby events" feature despite location permissions being requested.
3.3 Ticket Purchase Flow
Critical5-step purchase flow is too long for impulse ticket buying. Registration form has 12 fields without auto-fill. No guest checkout option — 34% of users drop off at mandatory account creation.
3.4 Navigation
GoodBottom navigation is intuitive with clear iconography for Events, Tickets, Wallet, and Profile. Event categorization by type (concerts, sports, festivals) is well-organized. Back navigation works consistently.
3.5 Accessibility
WarningMissing alt text on 60% of event banners. Touch targets below 44px minimum on seat selection and filter chips. Color contrast ratio fails WCAG AA on the QR display and ticket detail screens.
3.6 Error States
WarningEmpty states show generic 'Something went wrong' without actionable guidance. No offline ticket access — critical for venues with poor connectivity. Previously purchased tickets should be cached locally for entry scanning.
Security Assessment
58/100Critical Vulnerabilities — Immediate Action Required
4.1.1 Hardcoded API Keys
Stripe payment gateway keys and Google Maps API credentials found in client-side source code. These can be extracted via APK decompilation. Risk: Unauthorized ticket purchases, fraudulent transactions, financial exposure.
4.1.2 Insecure Data Storage
User authentication tokens and QR ticket data stored in SharedPreferences/UserDefaults without encryption. Rooted/jailbroken devices can access plaintext tokens and duplicate tickets. Risk: Account takeover, ticket duplication fraud.
4.1.3 Missing Certificate Pinning
App accepts any valid SSL certificate without pinning. At crowded event venues with public WiFi, this is extremely dangerous. Risk: Payment data interception, ticket theft, credential harvesting at scale.
4.2 Security Summary
| Category | Issues Found | Severity | Status |
|---|---|---|---|
| Authentication | 2 | High | Needs Fix |
| Data Storage | 3 | Critical | Needs Fix |
| Network Security | 2 | High | Needs Fix |
| Input Validation | 1 | Medium | Warning |
| Permissions | 0 | — | Passed |

Architecture Observations
- 5.1Flutter project follows a reasonable folder structure but lacks clear separation between data, domain, and presentation layers
- 5.2State management mixes Provider and setState() — recommend standardizing on Riverpod or BLoC for consistency
- 5.3API service layer has no abstraction — direct HTTP calls for ticket, event, and payment APIs scattered across 23 files
- 5.4No dependency injection framework — QR scanner, payment, and auth services instantiated directly, creating tight coupling
- 5.5Local ticket database migrations not versioned — risky for ticket data integrity during app updates
