Important and versatile calculator for Compressionists

You can call me . . . no you can't!

Absolutely important and useful app for anyone who does compression for any purpose. The ability to entire the variables so one can target a bitrate, file size, pixel resolution and bits per pixel makes this an all in one versatile utility. I can now do my compression on my desktop and just open my iPhone or iPad to figure out what I need to enter to hit my compression target.
