Editing transactions on the iPhone is simple.
1. Tap on the Budget Item where you have tracked the transaction. If it is not tracked, it will show up on the bottom of the screen as an orange coin.
2. Tap on the transaction you want to edit. You can edit multiple elements such as the merchant name, the amount, the date, the check number, and the Budget Item it's assigned to.
3. Once you're done making changes, tap "Save" in the top right corner and you're all set.
