I've been using Account Tracker by Graham Haley for years. I've ventured out looking for better apps and they just don't exist. I'm not 100% sure about syncing between Mac and iOS but account traxking and budgeting are locked down and backup through iCloud and Dropbox and baked in.
The ability to create your own account categories with separate balances displayed is the one option that I have so much trouble finding elsewhere.
