I did this with a single sheet of engineering graph paper in the 1980s. Rows were spending categories and columns were months and annual summaries. I spreadsheeted it in the 1990s and clouded it in the 2010s. Simple and powerful if you can see it all on one page. Takes just minutes a month. Most the mobile apps I'ver seen use too small screenfulls. And I DONT TRUST THEM INTO MY WEB ACCOUNTS like Mint wants to do.
