I use ledger myself, but the issue I always run into is my wife is much less likely to keep track of what she buys and let me know so I can record it. Where that gets especially tricky is when she goes someplace and leaves a tip. Resolving tips is a real pain in the butt, especially since it comes through in the checking account at the original price and is then later processed at the tip-included price. Matching those up is a real bear.
