Fact: finances are not straightforward. Banks have significantly improved their user interfaces and beautiful apps like Mint [1] have made managing money less painful, but calculating how much you can spend without going broke is a little bit of a science.

If you're the type that cares less about pie charts and more about what exactly you can spend today, this week, and this month, then Level Money is right up your alley. The app is free for iOS [2] and just launched for Android devices [3].

It took less than five minutes for the finance app to link to my savings, checking, and credit card accounts. Level Money can pair with most major banks, including Bank of America, Chase, Citibank, PNC Bank, and Wells Fargo, as well as a handful of credit unions.

After analyzing income, bills, and money saved, Level Money calculates a spendable amount and translates this to a daily, weekly, and monthly spending limit. These numbers are presented in a clear and elegant way. If they seem off, tap on the circle to reveal the math behind the amount.

As you make purchases throughout the day, the app notes the activity and automatically subtracts it from your daily limit. The number that you see when you open the app is the current amount you can spend, in real time. Unfortunately, you cannot add purchases made by cash — Level Money can only detect credit or debit card transactions. It will see when you've withdrawn money from an ATM, but it will not allow you to add a description to that withdrawal.
