So I am new to this forum and I have just recently gotten my ipad 2 (after a long and exhausting search haha). I'm currently investing in the stock market and I use excel to keep track of everything. This also involves using lots of formulas that affect my numbers. E.g. When I change the price at which I bought a stock my profit will change. I am looking for an app that will respect those formulas, meaning whenever I change one number it'll change appropriately anything else affected by a formula. Hopefully I make sense haha. So anyone know of any apps like this? I'm willing to pay up to $40. Thanks guys!
