Thunder Benchmark

This application puts your Android device under a heavy stress and measures the exact amount of flaw in it's performance.
Tests include multi-layer 2D effects using the device GPU as well as various mathematical algorithms which are artificially creating abnormal levels of stress for a short duration. Another test manages to fill in large amounts of data into the RAM in order to test the memory's actual speed.
The current release is absolutely free and does not require an internet connection.
