I went through about 10 budget apps trying to find one that would meet my needs, and this is definitely the one. I wanted to set budgets weekly, monthly, and by variable time periods which were a set limit from which my expenses were deducted.
This app provides deductible budgets, including a ROLLOVER feature between time periods for budgets (i.e. If you have money left over from one week, you can carry it over to the next week if you wanted to), has an OPTIONAL income budget (which is what I needed), and has a clean-looking interface with the upgrade for removal of ads for only $1. Generally easy to navigate and offers many different currencies (I needed PHP). You can actually search through your transactions, and the entry page for expenses allows (but does not require) a lot of details such as the exact date and TIME you made a purchase and notes about the purchase (which are included in the search function). You can also set notifications to remind you to update your budget :)
My only complaints about the product are minor:
Some of the button positioning and functions could be changed to make it easier, such as when you're adding an expense. I also wish the date control was not limited, but I'm assuming the date limits are to prevent accidental inaccurate records.
All in all, definitely a great app considering my needs and considering what few budget apps are available, especially with these features 👍🏽
This app also allows saving to Dropbox and iCloud!!
