Is it really an app?
An app serves a purpose (e.g. making a reservation, checking finances, playing a game). If opening and swiping to close or taking up memory is an app, then this is qualifies. Outside of that, this is pretty much non-functional. Barclays would best served to scrap this trash and give it some high school STEM students as a project. They could make a better app then what is offered here. The colleagues deserve better!!
