Qapital is an app that helps users achieve financial goals via setting rules on themselves.
There are some fun rules that could be set. For example, round up very purchase to the nearest $2 and save the difference. Or Spend less than $30 at Fresh & Co during a single week and save the difference. Basically the cool thing is that it lets users see the money they save immediately after they follow the rules.
Its business model is similar to Digit that is to generate revenue via creating a saving account for users and keeping the money saved by users.
In addition, like Mint, it requires the online banking user name and password. The user interface is nice and simple, which is important for financial apps.
