For what? Clicking a “pay this person $5 a month” button? Maybe commenting on a post or watching a video? I don’t see how the platform could affect that in any significant way.
Any sort of audio/video control for sure, which is a substantial portion of patreon content. Also, if you want to support offline content, it's nearly impossible to do it in a browser.
The app is better for viewing the content you paid for. Patreon is not just for subscribing to creators. They also deliver content. This isn't hard to understand.
