There is no downloadable calculator for Omaha that i am aware of. But you can use some on other websites. Can't post the links here, but a Google search will find them.

Try Omaha Indicator, dont know if its any good, tracker and calculator. PT3 now does a HUD and tracker. But as shokaku points out if you google there are lots of free calculators around.
If you want a calculator to see if you were good or bad in a hand after the fact just google omaha calculator.This are often the only way to tell if you were good or bad in a 3 or 4 way pot all in preflop. Especially if you go onto high low.
If your meaning an omaha preflop hand guide it really is not that important compared to holdem. As a hand preflop will quickly change. AAxx is not the monster that some people assume. Especially not with stacks that are at all reasonably deep.
If you mean on the fly while you play then i would advise you simply learn to "count your outs" and analyze the board to see what the nuts are. Each card you think that would give you the nuts is about a 2% chance of hitting. Open ender gives you 8 outs at 16%. Open ender on a flush draw board drops you down to 6 outs and 12%. Something like 789x on a 6Tx board gives you 9 outs and 18%. 78Tx on a 69x board will give you 13 outs and be roughly 26% with one card to come.
Im not exactly sure if any of these things answer your question. But i hope they help anyways.
Type on google and you will find an PLO equilator Just play an over pair + nutflushdraw or better agressive postflopand it si just such a fishy game PLO. NL is drying out.
