Smart Budget 2 is even smarter:
• instant start
• more powerful analysis
• full text search
• data sync using iCloud
• using sheets as shopping lists for projects (using planned operations with no date set)
• storing all day-to-day operations on single sheet
• deleting sheets and accounts, moving operations between sheets and accounts
• hiding unused accounts
• decimal arithmetics (no more rounding errors)
• context-sensitive help
• new design

It also keeps features that made Smart Budget 1 popular:
• data sync between devices using different Apple IDs for iCloud, or not using iCloud at all
• fast switching between multiple databases
• drawing of stylish category icons with your finger
• powerful multi-currency
• export to spreadsheet applications
• fast to learn

Some improvements did not get into version 2.0, but we are working on version 2.1 already.
