I use Monzo, a new UK bank much like Revolut. It's awesome for breaking down your spending habits and allows you to save where you can afford to.

I couple that with the Moneybox app, which invests about £150pm for me into global index and property funds automatically.

I also dabble with investing (manually) in stocks & shares, and crypto markets.

I don't use any software to keep track of everything, I just keep a keen eye on the aforementioned services.
