When I first read your comment I thought you were writing about Artha (due to the topic title) but rereading I realised you are referring to the HSBC app which is of course different.
With Artha it seems (unless I am missing something) that you can only see your spending over the last month which is less interesting and less useful…
To add an FD account you need to input the account password and memorable data, but if you background the app to copy these from your password manager, it clears the other entry!
Artha is pretty useless at the moment unless you exclusively use Amex cards.
I imagine when they add other Fin Techs such as Nutmeg, Moneyfarm etc they will do better. But at the moment, you can only add them as bookmarks. Which is utterly useless.
