Because people are stupid. We had a new client whose employees were asking for an app to access their payroll. I told the manager we didn’t have one but our website was optimized for mobile. Also told her I can show them how to put a shortcut on their home screen.

“They’re just not going to be able to handle that. If they can’t download from the app store they’re helpless.”

“But they’ll have an icon to click, just like an app.”

She just shook her head. I ended up wrapping the site in an app and putting it in the Play Store.
