Is there any personal financial app that's not a POS?

I have used Every Dollar, Mint and most recently Personal Capital apps. Paid all of them for their premium service if they offered one and a few other apps aswell.

All of them are trash. I cant keep a card or investment account linked to it for longer then like a week before I have to re-sync them all over again and that’s if they even sync.

Why use these apps of they cant even sync/track your stuff? It’s not like I’m asking them to sync with crazy no name investment firms or credit cards. There is no reason why I should be paying for a service that cant maintain an account link to my accounts. Most of all when that’s what you market your product as its primary function.
