SitNGo Wizard probably does far more than I can tell you - but just the small amount of time I spent in it last night here is what I know so far.
It collects your hand histories and analyzes them for you. It will tell you which hands you played wrong and what you should have done instead. It gives you the ranges for that play as well.
For example if you folded and should have shoved it will tell you that and show you the hands you would shove with.
I had very few hands that I played incorrectly and most of them were marginal so it was okay.
I can hardly wait to get back in there today after I play some more sng's.
You can download it for free for 30 days so you have nothing to lose by trying it. And after that it only costs $45.
You can not have it open while playing though - so make sure it is closed and that you remember to close your poker sites before you launch it.
I think the sites are fine with it being used as a review of your hands - but not something you can use while you are playing as it would give you an unfair advantage over the other players.
Just a little advice on SNG Wizard : don't trust what SNG Wiz tell you at first because their default calling and raising ranges are a bit messy.
They now ask for feedback on this (basically by user allowing the software to auto-feedback the hands they put to SNG Wizard support) but last time I used it (which should be around july I think) you still have to make adjustments to get a good result.
Instead go through each hand where you pushed/called a push or fold to a push preflop (yeah forgot to mention for those unfamiliar with SNG Wiz : this piece of software is just about push/fold preflop situations but that's basically what you like to do with ICM tools
).
Then for each hand adjust calling and pushing ranges for your opponents the way you think it should reflect reality.
Then you will have some SNG Wiz advice to trust for.
I'll probably try to play a mix of MTT, SNG and 6 max cash this month depending of the time i got to play each day.
Probably going to 10-20's $ MTT and SNG and 50NL but i'll take a look at this thread daily.
Take care all and good luck at the tables.
