I recommend that you get a native English speaker to go over the things your write. For example, this:
Get the Enpass now
Whatever your device maybe, we have an Enpass for you.
Is not the way a native speaker would write it. It should be
Get Enpass Now.
Whatever your device may be, we have an Enpass for you.
or better:
Get Enpass, Now!
Whichever devices you have, we have a version of Enpass for you.
I love Enpass, but when I see mistakes like this, I start to worry about the app.
I hope that helps you.
