Learn the game, not a textbook
Nobody becomes a fan by memorizing a rulebook. Onside teaches you what you need, in the order you'll actually need it.
Start with the basics
Each pillar opens with the essentials — offside in one sentence, who does what on the pitch, why everyone's singing. Free, always.
Ask anything
"Why did the ref do that?" "What's a brace?" Ask Onside answers privately on your device — the friend who explains without the eye-roll.
Follow your first season
Pick a club, learn the calendar, and walk into matchday — or the group chat — knowing exactly what's going on.
Five pillars. Zero gatekeeping.
The Rules
Offside, cards, penalties, VAR — every rule in plain language, with the "why" behind it. One sentence first, detail only if you want it.
The Positions
Who does what on the pitch, from goalkeeper to striker — and what a fullback, a winger, or a number 10 actually means when commentators say it.
The Tactics
Formations, pressing, counter-attacks, and what xG actually measures — enough to see the chess match inside the game, no coaching badge required.
The Culture
Chants, rivalries, scarves, how to pick a club, and how to survive the group chat. The unwritten stuff nobody explains — explained.
The Calendar
Leagues, cups, and how a season fits together — plus what's ahead: the Women's World Cup 2027 in Brazil, Euro 2028 across the UK & Ireland, and the World Cup 2030 in Spain, Portugal & Morocco.
Ask Onside
An on-device AI explainer for every "wait, what just happened?" — answered privately on your phone, in plain language, zero judgment.

Questions
I know nothing about football. Is this for me?
Yes — that's exactly who Onside is for. If you got into the game through the World Cup and you're about to follow your first full season, Onside starts from zero and never makes you feel behind. No dumb questions.
Is it only about the Premier League?
No. Onside explains the game itself — rules, positions, tactics, culture — which works for any league or tournament. The calendar pillar covers how leagues, cups, and international tournaments fit together, so you can follow whatever hooked you.
What can I ask the AI?
Anything about the game — "why was that offside?", "what's a false nine?", "how does relegation work?" Ask Onside runs on your device, so your questions stay private. Free includes 3 questions; Pro makes it unlimited.
Do I have to pick a club?
No — but it's more fun with one, and Onside helps you choose without the gatekeeping. A player you love, a city you feel connected to, a shirt you like: all legitimate reasons. "Wrong reasons" don't exist.
What does it cost?
Onside is free to start — the basics of all five pillars plus 3 AI questions. Onside Pro unlocks the deep dives across every pillar and unlimited Ask Onside, as an auto-renewable subscription through Apple.
Ask Onside answers are generated by on-device AI and, like all of Onside, offer general football education for new fans — a friendly explainer, not an official source. Rules and competition details can change; check official sources for anything that matters.
