Not really, I used to work at one of the main Facebook SPMDs so I'm saying that out of having seen the performance of mobile app campaigns on advertisers that spend $100k+ a day on fb. I don't see why you would be hated by your users? The ad makes it super clear that it's an app, it takes you straight to the app store where you can read reviews / description / screenshots and then you just install it. I think you are making the mistake of thinking that the average user is like you, most people will just want to get the app ASAP when they see an ad for something that seems useful; not having to navigate a website which doesn't have a mobile version (try budgetsimple.com in an android phone, it's impossible to use !)
