Plash App Beta feedback

Download package name and app name should be same. I downloaded NewsAppMagazine and was looking for that after installing. Didn’t find it.

The download should be from plash.in - not a random box.com link

Login screen

Don’t need the “login” word on top of textboxes. The bottom “Login” button is prominent enough call-to-action.

Remember or Remember Me instead of Remember password

Create account screen

Placeholder text should be subtle-r

The date controls in the DOB field are not working. Shows some category dropdown, not dates.

can’t un-specify gender (even though it’s not required)
