I like that it allows me to check my account balance, make transfers from one bank or credit card accounts into another without having all of those transactions reflected in multiple statements at once! It is not as user friendly for customers with less experience using their smartphone than myself (I do have some).
The interface could be simplified/customized so more users would feel comfortable navigating through its features easily - there are many unnecessary steps between basic login functionality such as username & password inputting and viewing your current balances etc., which can get overwhelming quickly when you first log-in after logging out previously. Also, sometimes they will only let you add funds up until certain amounts before requiring additional payment methods / information if necessary. This has been helpful because this helps us avoid giving our clients too much money upfront since we don't want them paying any fees unless absolutely needed.
