```
I've checked those against the standard iOS limits:

Your metadata is currently safe for submission.
```

**Prompt:** 
```
Analyze the keyword density for this description: 'Best racing game with fast cars and nitro boosts.' using keywords ['racing', 'cars'].
```

```
Here is the keyword density for your description:

| Keyword | Count | Density |
| :--- | :--- | :--- |
| **racing** | 1 | 10% |
| **cars** | 1 | 10% |

Both keywords are well-balanced and shouldn't trigger any spam filters.
```

No, your short description is perfectly fine.
