Simple Login has been abandoned for 4 years now. The apps are extremely outdated. Addy.io (the competition of SL) has been taking strides in development during the past few months. Their apps are very modern, feature rich. SL can't even replace capital letters by small letters and gives errors all the time when creating aliases. Mostly autofill doesn't work as we have to click and edit the auto filled email or it doesn't register on most websites. It just visually populates the field but doesn't really type anything unless you edit it.
