A free app for Android, by Alan Robinson.
This app is designed to help you find out if your SD card is a reliable one or if it is a fake. To do this, we use a number of tests that are designed to be accurate. We do this so you can rest assured that what is written to your SD card is indeed what is there. If the test shows that your SD card is unreliable, then you need to decide what to do next. You need to either repair or replace your SD card, and we have no other alternative but to give you some kind of a solution.
