Detailed Findings by Category¶

1. Security Assessment¶

Overall Security Score: 45/100 🔴 Critical Risk

Compliance Status:
- ❌ OWASP Mobile Top 10: 30% compliant (3 of 10)
- ❌ HIPAA (Health Data): Non-compliant (multiple violations)
- ❌ GDPR (EU Users): Partially compliant (missing consent, data encryption)
- ❌ PCI DSS (Payment Data): Non-compliant (payment data mishandling)

Vulnerability Breakdown:

Most Critical Vulnerabilities:

1. CRITICAL-001: Hardcoded API Credentials (CVSS 9.8)
   

   // Utils.java - Line 23
   public static String BaseURL = "https://api.psyter.com/api/";
   public static String ApiKey = "psyter_live_key_3a8f9b2c..."; // Exposed!
   

   
   Impact: Anyone can decompile APK and access production API with full permissions.
   Exploitation: Trivial (APK decompilation tools widely available)
   Remediation: Use BuildConfig or secure key storage

2. CRITICAL-002: Unencrypted Password Storage (CVSS 9.1)
   

   SharedPreferences.Editor editor = prefs.edit();
   editor.putString("password", userPassword); // Plaintext!
   editor.apply();
   

   
   Impact: Any app with root access or backup extraction can read passwords.
   Affected Users: 100% of users
   Remediation: Use EncryptedSharedPreferences

3. CRITICAL-005: Payment Data in URL Query Strings (CVSS 7.5)
   

   String url = PaymentURL + "?cardNumber=" + cardNumber + 
                "&cvv=" + cvv + "&expiry=" + expiry;
   

   
   Impact: Payment data logged in server logs, browser history, analytics.
   Compliance: PCI DSS violation
   Remediation: Use POST body with HTTPS

Total Security Remediation Required

2. Code Quality Assessment¶

Overall Code Quality Score: 52/100 🟡 Fair

Key Metrics:

Top Code Smells:

1. God Objects (5 files)
   - Utils.java - 2,031 lines, 150+ methods (networking, UI, validation, dates, images)
   - CollaborationMain.java - 3,000 lines (WebRTC, UI, signaling, permissions)
   - CalendarCustomView.java - 2,200 lines (rendering, events, calculations)
   - WeeklyScheduleFragment.java - 2,700 lines
   - BaseClientActivityMain.java - 1,400 lines

2. Exception Handling Anti-Pattern (100+ occurrences)
   

   } catch (Exception e) {
       e.printStackTrace(); // Only logs to console, no user feedback
   }
   

3. Code Duplication (15%)
   - 20+ adapter classes with 80% identical code
   - 300+ API calls with same boilerplate
   - 150+ Glide image loading blocks

4. Callback Hell
   - 5+ levels of nested callbacks in networking code
   - Hard to read, harder to debug
   - No error handling in nested callbacks

3. UX & Accessibility Assessment¶

Overall UX Score: 58/100 🟡 Fair
WCAG 2.1 AA Compliance: 35% 🔴 Fail

User Flow Issues:

Accessibility Violations:

• Legal Risk: ADA lawsuits in US, accessibility laws in EU
• Lost Users: ~15% of users have disabilities (WHO estimate)
• App Store Rejection: Apple/Google require basic accessibility

Error Messaging Quality:

• ✅ Good messages: 30% (“Invalid email format”)
• ⚠️ Vague messages: 40% (“Please try again”)
• ❌ Poor messages: 30% (“Something went wrong”, “Error occurred”)

4. Performance Assessment¶

Overall Performance Score: 55/100 🟡 Needs Improvement

Performance Bottlenecks:

Root Causes:

1. No Pagination - Loads 1,000+ providers in single API call
2. No Image Caching - Re-downloads images every time
3. Main Thread Blocking - Heavy JSON parsing, bitmap operations on UI thread
4. Memory Leaks - WebRTC resources not released, Activity context held in callbacks
5. Inefficient Layouts - Nested layouts cause overdraw

5. Architecture Assessment¶

Overall Architecture Score: 65/100 🟡 Moderate

Current Architecture: Hybrid MVC with Repository-like patterns

Strengths:
- ✅ Clear separation of Activities, Fragments, Adapters
- ✅ DataModels for API responses
- ✅ Custom views encapsulate logic
- ✅ WebSocket management centralized

Weaknesses:
- ❌ God objects violate Single Responsibility Principle
- ❌ Static Utils class creates tight coupling
- ❌ Mixed UI and business logic
- ❌ No dependency injection
- ❌ No clear data flow
- ❌ Hard to test (0% coverage)

Recommended Architecture: MVVM (Model-View-ViewModel)

5. Provider Reviews/Ratings - Users want to see feedback from others
6. Appointment Reminders - Reduce no-shows
7. In-App File Sharing - Homework requires external apps
8. Offline Mode - View past appointments without internet

7. Technical Debt Assessment¶

Debt Breakdown:

Debt Impact (Cost of Not Fixing):
- Security: Data breach risk, legal liability, reputation damage
- Code Quality: Slower development, more bugs, developer frustration
- UX: User churn, accessibility lawsuits
