Burner: Second Phone Number positions itself as a privacy-focused communication tool that enables users to create temporary, disposable phone numbers. Developed by Ad Hoc Labs, Inc, the application addresses growing concerns about personal information exposure in digital interactions. With a 4.3-star rating on Android platforms, the app serves users who require temporary communication channels without compromising their primary contact details. The core functionality revolves around generating virtual numbers with selectable area codes, enabling unlimited SMS messaging and voice calls through Wi-Fi or mobile data connections. The 'burn' feature allows immediate number disposal, providing users with control over their digital footprint. The application operates independently from the user's primary carrier number, creating a separate communication channel that can be activated or terminated at will. User experience centers around a straightforward interface that facilitates quick number generation and management. The design prioritizes functionality over aesthetic complexity, with clear options for creating new numbers, accessing message history, and managing existing lines. Real-world usage patterns indicate frequent application in online marketplace transactions, dating scenarios, and temporary business communications where users prefer not to share permanent contact information. User feedback reveals consistent appreciation for the privacy protection aspects, though some operational inconsistencies have been reported. The review from D Gro on June 11, 2025, demonstrates initial technical issues followed by satisfactory resolution: 'Was working great and then was not... they fixed everything and it works perfect now.' Another user, Midget Mash, noted on August 14, 2025, how the app provided 'peace of mind in catching a lying spouse so that my personal number is not advertised,' highlighting its utility in sensitive personal situations. The application demonstrates significant strength in providing immediate privacy solutions but faces limitations regarding long-term reliability and customer support responsiveness. While the core functionality meets basic privacy needs effectively, users requiring consistent communication channels might encounter occasional service interruptions. The ideal use case involves short-term interactions where maintaining personal number confidentiality outweighs the need for permanent contact solutions.
