I have no idea, but I'd assume the mobile app would be for use of the people receiving the money. Which would be a nice add if I were a content creator. But that's just a guess.
Edit: As for your notion that an app isn't necessary when there is a well-designed mobile site, I def agree. However, that's just not the case anymore, how else do you expect companies to so easily collect your personal data! /s
Edit2: Id wager some companies intentionally don't focus on having a nicely compatible mobile site. For example, my bank's website sucks when I visit from a mobile web browser, however their app is great. I believe this is their intention, in order for people to download their app. Which has obvious benefits for the company; in particular, the data collection
yeah agreed. I prefer to not have to use an app if I don't have too. Or unless there's some great benefit that the app has that the mobile site doesn't
Why on Earth would I need a mobile app to use this? What does it provide that a well-designed mobile site doesn't?
