We use this to track allowance and savings for three kids, plus discretionary funds for the parents. Two iphones have edit control, while the kids ipads only show their individual accounts. It syncs via dropbox and uses very little space.
The sync function had gotten slow for us after 8 months. Their support group told us exactly how to correct this, and syncing is back to a couple seconds. Very happy!
