Start here: what is zero-based budgeting?
Zero-based budgeting means income minus planned spending, saving and debt payments equals zero: every pound or dollar is given a job before the month starts. Envelope budgeting is the same method with one named envelope for each category, so you can see what is left to spend.

Apps and alternatives: which budgeting app should I use?
Budgeting apps differ on three things that decide the choice: what they cost over several years, whether they need an internet connection or a bank login, and whether your data lives on your device or on a server. These pages compare them.
Your situation: how should I budget with my income?
How you are paid changes the first step. Weekly pay, monthly pay, an irregular income and a low income each need a slightly different setup, and so does money spread across several accounts. These guides give the steps with worked numbers.

Saving: sinking funds and an emergency fund
A sinking fund is money set aside a little at a time for a bill you know is coming, such as a car repair or an annual premium. An emergency fund covers the costs you cannot predict. In a zero-based budget both are categories that you fund before the month starts.
