All these finance aggregation apps such as NerdWallet are horrible

Can't find one that doesn't have tons of flaws. My mortgage was recently sold to another bank. I changed the linked accounts in NerdWallet from the old one to the new one. Because there was a moment in time where the old account became $0 (because another bank bought it!), NerdWallet rewrote my history to subtract mortgage balance from previous years .... showing this fake net worth from previous years before a recent fake cliff. Another annoying and related thing about NerdWallet is that it only keeps data from the time when you installed the app. PersonalCapital is a better app in that regard, but it has different problems. Both suck. Is there anything better out there in the app market?
