# django.core.exceptions.ImproperlyConfigured: Application labels aren't unique, duplicates: myapp

- **ID:** `python/django-app-not-registered`
- **Domain:** python
- **Category:** config_error
- **Verification:** ai_generated
- **Fix Rate:** 80%

## Root Cause

Two different apps with the same app_label are registered in INSTALLED_APPS.

## Version Compatibility

| Version | Status | Introduced | Deprecated |
|---------|--------|------------|------------|
| 3.x | active | — | — |

## Workarounds

1. **Change app_label in AppConfig** (95% success)
   ```
   class MyappConfig(AppConfig):
    name = 'myapp'
    label = 'myapp_unique'
   ```
2. **Remove duplicate app entry** (90% success)
   ```
   Remove one of the duplicate entries from INSTALLED_APPS.
   ```

## Dead Ends

- **Removing both apps** — Loses functionality. (70% fail)
- **Renaming app folder only** — app_label remains same. (90% fail)
