1. Limited Features in Free Version: OKEN - CamScanner, PDF Scanner may offer a basic free version with essential functionalities. However, users might need to purchase a subscription or unlock specific features through in-app purchases, which could be a barrier for those seeking a comprehensive free scanning solution.
2. Intrusive Ads: The free iteration of OKEN - CamScanner might contain ads that can disrupt the user experience. These ads can be annoying, especially when users are trying to scan documents quickly, and may lead to accidental clicks, which is frustrating for users.
