Store description excerpt
CellWatch allows you to measure your mobile network's download speed, upload speed, and latency so that you can know where to find good Internet performance. Measurements can be submitted to the FCC as part of their official mobile broadband challenge process to prove that your carrier isn't providing good service in a specific location. All measurement data is sent to CellWatch's central database to help build a more accurate picture of what cellular coverage looks like throughout the United States. FEATURES - Measure download and upload speed (throughput) and latency. - Submit measurements to the FCC's mobile broadband challenge process, or only send them to CellWatch's central database. - View your past measurements on a map as individual points or grouped according to the hexagonal grid used by the FCC challenge process. - View your past measurements in a list. - Export your past measurements to a JSON file. - Available in both English and Spanish. PRIVACY CellWatch protects your privacy as much as possible while still creating a useful repository of cellular measurement data. All measurement data is sent to CellWatch's central database. This data is published publicly at most 4 times per year. The public data releases include generalized locations (within about 1/8 mile), generalized timestamps (in 4 hour buckets), an anonymized device identifier, and your device's manufacturer and model. Data is also collected by the Measurement Lab (M-Lab), a non-profit open source project, during the measurement process. This data includes your device's IP address, a timestamp, and the network measurement data. M-Lab does not collect location data or device details. If you choose to send mobile broadband challenge measurements to the FCC, they may share your data with your cellular provider and with the public. For more details, see the CellWatch privacy policy at https://sites.gatech.edu/cellwatch/android-app/app-privacy-policy/. TEAM CellWatch is created by researchers from the Georgia Institute of Technology; the University of California, Santa Barbara; and Northern Arizona University. Development is generously funded by the Rockefeller foundation.
