Opensignal is a freely accessible mobile application designed to provide users with comprehensive insights into their mobile connectivity and network signal performance, without the intrusion of advertisements. The application's core functionality revolves around conducting speed tests to accurately assess the quality of a user's mobile and Wi-Fi internet connections. These tests involve a series of evaluations, including a five-second download test, a five-second upload test, and a ping test, all of which contribute to a holistic understanding of the user's internet speed. Opensignal strategically employs common internet Content Delivery Network (CDN) servers to ensure the reliability and consistency of its speed test results. The final internet speed measurement is derived from the median range of the collected data samples, enhancing the accuracy and representativeness of the reported speed. Beyond basic speed testing, Opensignal offers a video playback test that delves into the intricacies of video streaming performance. This test simulates real-world video viewing scenarios by playing a 15-second video snippet and meticulously monitoring various parameters such as load time, buffering occurrences, and overall playback speed. By analyzing these factors in real-time, Opensignal provides users with a clear understanding of the expected video streaming experience on their network, distinguishing between High Definition (HD) and Standard Definition (SD) video quality. The application's connectivity and speed test coverage map further enriches the user experience by visually representing network coverage and speed data. This map utilizes data gathered from local users' speed tests and signal measurements to depict signal strength at a granular level, down to the street level. This feature empowers users to identify areas with optimal network coverage and the fastest internet speeds. Opensignal also aggregates network statistics for local network operators, enabling users to proactively assess coverage in advance of travel, evaluate internet and download speeds in remote locations, compare network performance against other providers in the vicinity, and make informed decisions about selecting the most suitable local SIM card. The cell tower compass is an additional tool provided by Opensignal, designed to assist users in identifying the direction from which the strongest network signal originates. This feature facilitates the use of broadband and signal boosting technologies by providing directional guidance. However, Opensignal acknowledges that the cell tower compass relies on aggregated data and may encounter accuracy limitations in certain areas, emphasizing the ongoing efforts to refine and enhance this feature. Furthermore, Opensignal diligently tracks and records the time users spend connected to different network technologies, including 3G, 4G, 5G, and Wi-Fi, as well as instances of no signal availability. This tracking enables users to monitor the consistency and quality of the service they receive from their network provider, facilitating informed decisions about their mobile plans and service usage. In cases where the provided service does not align with expectations, users can leverage the collected data and individual speed tests to effectively communicate connectivity and signal issues to their mobile network operator, fostering improved service quality and resolution of network-related problems.
Opensignal operates as an independent and transparent platform, offering unbiased insights into the mobile network experience. Its primary objective is to provide a reliable and objective data source that reflects the real-world experiences of users in terms of mobile network speeds, gaming performance, video streaming quality, and voice service reliability on a global scale. To achieve this, Opensignal collects anonymized data related to signal strength, network characteristics, location information, and other relevant device sensor data. Users retain control over their data sharing preferences and can opt out of data collection at any time through the application's settings. The data collected by Opensignal is shared with network operators and other stakeholders in the telecommunications industry to promote the advancement of mobile connectivity for all users. By providing valuable insights into network performance and user experiences, Opensignal contributes to the ongoing efforts to optimize network infrastructure, enhance service quality, and address connectivity challenges worldwide. The company encourages users to review its comprehensive Privacy Policy for detailed information about data collection practices, usage policies, and user rights. The Privacy Policy outlines the measures taken to protect user privacy and ensure data security. Opensignal is committed to complying with applicable data privacy regulations, including the California Consumer Privacy Act (CCPA).

This option is accessible through a dedicated link, empowering users to control the use of their data. Opensignal emphasizes the importance of transparency and user empowerment in its data handling practices. The application requires certain permissions to access device features and data necessary for its functionality. Specifically, Opensignal requests location permissions to display speed tests on a map and to contribute to network statistics and network coverage maps. Location data is used to provide context-aware insights into network performance and coverage. Additionally, Opensignal requests telephone permissions to gather more accurate data on devices with dual SIM capabilities. This information is used to improve the accuracy and reliability of network measurements. Opensignal is committed to using these permissions responsibly and transparently, ensuring that users are informed about the purpose and scope of data collection.
