I use Tiller to track my finances in a spreadsheet.
I have more accounts than their net-worth template can handle without semi-recurring modification. The template uses complex enough formulas to make it more than a minor inconvenience.
I make efforts to minimize the number of accounts I have, but I still have a brokerage account, IRA, ROTH IRA, Wife's IRA, Wife's ROTH IRA, HSA, 401k, old 401k ($0 balance, but showing for historical purposes), and a few real estate investments. My wife is starting a new job, which means a new 401k, and something else to break.
