It's a good hand warmer

Take your phone out of the case and set 99999 runs and watch the heat generate

Incorrect results and crashes

A problem size of 4096 reports 170 GFLOPS on an iPhone 5. 8192 causes a crash.

Nice- exactly what I was looking for

I'm consistently getting 112mflops average. Just wanted to see my CPU speed. I noticed I get higher mflops when using multiples of 8, like 256, 512, 768 etc. So I used all kinds of odd numbers and my A5 is pretty solid for being an A5.

I noticed the ads pause during test- this is the way a benchmark app should run.
