I've been running and using
HoneyMoney.io since 2011.
It's a manual tracking system, I feel that manual tracking leads to paying more attention to finances.
The best thing I like about it is that I use it as a financial journal.
For example, here's the breakdown of hotel costs during our 2015 road trip and total Amsterdam trip costs. Those transactions happened over multiple days and via different credit cards, cash, etc. It all did matter at the moment but then I simply combined all of them into one transaction per trip.
