PinSend is a tool designed for sharing text between devices using a simple PIN system, emphasizing ease of use and convenience. However, user feedback highlights several areas for improvement, particularly concerning security and functionality. Many users expressed concerns over the current PIN complexity and session management, suggesting that it needs to incorporate longer PINs, automatic session expiration, and the possibility of end-to-end encryption. There are also requests for better URL structuring for ease of access and the addition of QR code capabilities to streamline device connections. The lack of image sharing capability raises questions about its completeness as a sharing solution, and users are also curious about the business model underlying the service. Overall, while PinSend presents a neat solution for text sharing, enhancing security, incorporating features for multimedia, and clarifying its operational model could significantly improve its appeal and usability.
