The app works ... until you try to use it for found money then it becomes janky and a hassle. If your found money has an app, then you have to uninstall it because you can only get the investment money by using your browser, and not its app. But you have to uninstall the found money's app because when you tap the Order Now button in Acorns, it automatically opens the found money's app (all while telling you NOT to do it) and there doesn't seem to be a way to prevent that
