I also just use a spreadsheet. I don't trust apps to connect all my accounts--especially since a lot of my assets are offline. I also like the spreadsheet because on a monthly basis I track my net worth in dollars, bitcoin, and median and average home sales prices in the US--so I can see how many average and median priced homes my net worth can afford. Since these values are all in the sheet, I can also easily have it calculate each of my holdings in Bitcoin or house terms.
