Downloading an app directly without using app stores

Here is an email I sent to ALT:

"Unsolicited, I received an app for my business from appsme.com

The beauty is that it AUTOMATICALLY loads the app, without needing to go to apple store or anyone else's store..

in my case to load the app you go to:

theremedialmassageguy.appsme.com

You then ADD TO HOMESCREEN to put the icon on the desktop of the phone.

I then use a redirect from a domain name to hide the appsme part:

theremedialmassageguy.com

If you had a link on the pericoach website, perhaps only accessible if they login after buying the pericoach, to download the app without needing to go to any store, it would simplify the process and these one percenters all boost sales by making the purchase experience a little easier....
