I'm tracking all my expenses and income through this app.
It doesnt have fancy (?) features like linking bank account, reading sms and getting the balance automagically and other shit.
Just plain and simple.
I use the below app. Simple UI and good features. Tracking all expenses especially with multiple bank accounts and cash expenses is cumbersome. I do manual entries weekly or whenever I'm free.

Although it's not exactly a budgeting app more of a expense tracker.
YNAB will always be a good buy but if you don't want to pay for a budgeting app you can go with a free expense tracker.
I use Daily Expenses 3 . Was recommended to me by my accountant brother.

UI is not so 2016 but it is good.
