The developers have a great idea with this app, its very intuitive, looks and feels great, but it crashes after adding a second bill. Some values show up as NaN when you use decimals in US currency, not sure about others, and on iPhone after adding a second bill the future months do not show up anymore. I have this installed on both my iPhone 5S and iPad Air running iOS 7.0.6 on both.
I could definitely see myself using this app once the bugs are fixed, and I would give this app 5 stars. Especially for the price.
Even though there are bugs with this version I would still recommend the app to anyone wanting to manage their budget.
