To use the Android app, your Android phone must have version Android 4.0.3 or later installed.
To use the iPhone app, your iPhone must have version iOS 7 or later installed.
The apps will only run manual tests, which means that users must initiate each test cycle (which includes download, upload, latency, packet loss, and jitter tests). Each execution of these tests can consume up to 7MB of data with the fastest mobile technologies. Rest assured, the app is configured by default not to use more than 100MB per month, and you can adjust this data cap up or down to suit your individual data plan. You will get a warning when you have exceeded your data cap.
