Suggestions to Smarty

I want to suggest the app has the ability to have biometric login for the smarty Mobile app alot of the other mobile providers have that feature built built in. It certainly would make my life alot easier considering the smarty app keeps logging itself out all the time by itself or if you don't regularly open the app which is very annoying as you have to remember your password all the time just to view it which I know is for security reasons but still it is a feature I would like to see smarty Mobile put into the app which is biometric login
