iphone/ipod touch apps to edit excel data to determine bet?

[wix]

As I'm not that quick with positions of numbers on the wheel, I've came up with a spreadsheet which would determine what numbers to bet on based on my own system.

This spreadsheet is like any other spread sheet as it'll determine exactly how much I've won at each game, and how much I've exchanged, etc.

As I only go for real casinos, it'll be handy to have the spreadsheet ready in iphone.  All that is needed is to feed the spreadsheet on iphone with the previous spun numbers to determine my next bet.

The app needs to support these function:

Match
Vlookup
Count
and the usual maths operation, ie sum,etc

Has anyone come across Document2go or Officesuit? which is better?

I will be editing the data in offline mode,
