Simple I find this app useful. I do wish more explanation was given about the benchmark while using it. My phone is an LG G Flex 2: specs alone are not be the "be all" concerning benchmarks, even though my LG should "on paper" run over 60fps, giving me a much higher score over a Samsung Galaxy S4: I do believe that people on the top 50(not all) are using custom Roms. A great benchmarking Application overall; I recommend it to any seeking a worthy benchmark.
Does nothing I load the app and all it does is circle around a growing bonsai. Tried it about 6 times and does nothing.
Offscreen test You need one.
OK Nice, but not very usefull
Reliable, professional and awesome mobile benchmark for performance gurus.
