Mint.com (and the similar FinanceWorks, which some banks and credit unions provide it as a complementary product) is a great online tool by Intuit. It can automatically pull all the activity on your different financial services (e.g. savings, debit/credit accounts, investments, ...) and let you have a very efortless look into your finances. It also minimizes the chance you'll miss an erroneous charge or withdrawal on one of your accounts. Any cash transactions have to, of course, be entered manually. It has budgeting capabilities that are very basic but sufficient if you're already budget-minded.

YNAB is often recommended, it has grown into a much beefier product (from its humbler slightly-better-than-a-spreadsheet times) to a very robust tool. I have been told it does everything Mint does, but better (no idea how true that is). It moved from a fixed price to a yearly subscription, but people generally effing love it. I have yet to try it, because it doesn't offer anything I need over my current tools. The
old YNAB 4 ($60) has less features, but the price-tag is firm and one-time. You might want to google "YNAB 4 vs new" and see what the comparison is like.
[Free] MS Excel/Google Sheets/LibreOffice Calc. This requires manually inputting everything (like the old old YNAB), but that makes you spending-averse, and
very conscious about your expenses due to the inherent time commitment. This is great if you have more time than financial skills... Though then again you could spend the extra time saved with proper software watching budgeting/finance videos at Khan Academy or somesuch. There's great pre-made budget books for every spreadsheet software out there, just gotta search for them. I know Excel is not free, but the alternatives are... And it's an offline-only product anyway
