same here! using iCash since 2003, but really would like to have in addition iCash on iOS ...
It doesn't need to be a copy of iCash. All I need is an app on the mobile that allows me to type in the expenses that I have on the go and the ability to sync it to iCash once I get home. Overview and Transactions would be fine for me. On the iPhone or iPad I don't need Queries, Reports, Budgets or Statistics.
