Every system tells a story.
Answers are free now — any question your child asks, a machine will answer better every year. The hard part was never the answer. It is spotting that something is wrong in the first place, and that is the skill this app builds.

The part a machine will not do for them
Something is off
The missing part. The piece that does not belong. The step in the wrong order. Spotting it is the hard part — and the part no one teaches.
Find out why
Every case runs. Your child breaks it on purpose, watches the consequence unfold, then works out the mechanism.
Let them teach you
A technical note follows every solved case — the real mechanism, in language a child can repeat to someone else.
Then it comes home
A case does not end on the screen. Its last step is a conversation with you — and that is the step where the understanding actually forms.
Let's ask grown-ups
Every case ends with a question your child can now answer and you may not. Ask it at dinner, and let them explain.
Challenge a grown-up
They hand you a case they have already solved. You get no hints. Once you crack it, they explain why before you check the note together.
Your child's journey
Behind the grown-up gate: which kinds of fault they have practised, what they have learned about, and three questions to ask tonight. Worked out on the phone — no scores.
Four kinds of snag
Every mystery in the app is one of four. Once a child can tell them apart, the same method works on a batter that will not rise, a bicycle that slips its gear, a rumour, or a message someone forwarded.
Something the system needs is not there.
Every part is present — but one is not right.
Something sneaked in that does not belong.
All the right steps — in the wrong order.
One real case of each kind
Each is written up for grown-ups: what goes wrong, why it goes wrong, and how to talk it through with your child afterwards. All four are free to play.
What to put on a burn, and what makes it worse
Butter, toothpaste, ash and ice all make a burn worse, for the same reason.
⌖ ORDERA smell of gas: what to do, in order
Cooking gas has no smell of its own. What to do, in what order, and the one thing that must not happen.
⌖ MISSINGThe cooker that never whistles
Steam escaping round the lid and no whistle after thirty minutes points at one part.
⌖ EXTRAThe kindness that hurt the pond
Bread fills waterbirds without feeding them. How a small kindness, repeated, turns a pond green.
A real sky, earned one case at a time
Every case solved for the first time gives your child a real star — its true colour, how far away it really sits, and one true thing about it. The stars fill real constellations, drawn where they actually sit in the night sky. The last star of one draws the whole pattern, and the app says plainly that it is a good place to stop.
Earned and only earned. Nothing to buy, no coins, no streaks, and nothing is ever taken away.
Where should your child start?
Go by the class your child is in, not by how well they read. Nothing is locked — a child who finds one band easy can move up the same day, and you can fix the band in the Parents area if you would rather they stayed put.
👀 Explorer
Something needed is simply not there — and it can be seen. 28 free cases so far, the gentlest in the casebook.
Grade / Class 6–8🔍 Investigator

Grade / Class 9–12🕵️ Inspector
It works fine — until the load arrives. 13 free cases so far, faults that hide until they matter.
Under 5 years? Read this first — what actually helps before school age, and why we do not make screen apps for babies.
Safe by design
No account, no sign-in
Nothing to create, nothing to remember, nothing to leak. Progress lives on your own device.
No data collected
No analytics, no tracking, no third-party requests — even the fonts are bundled inside the app.
No links out, no chat
Nowhere inside the app for a stranger to reach your child. Every link on this website is for grown-ups.
Works fully offline
Download once on the train, play in the village. No connection needed after install.
Money behind a gate
Purchases sit behind a grown-up gate: a child can see a pack, but only a grown-up can buy it.
Reading for grown-ups
The nosebleed myth almost every child is taught
Tip the head back and the bleeding does not stop — it just goes somewhere you cannot see.
Birth to 5: what actually helps
The high-contrast science is real; the screen is the wrong way to deliver it. And why we will not build a baby app.
Newborn contrast patterns
Black-and-white patterns for the first six months. Paper, not screens — which is what the evidence actually supports.
Who makes this
Snag Academy is built by one family, with no investors who have a say in what goes into it. Every case about road safety, first aid, kindness, money sense and staying safe online is free. The paid packs go deeper into hands-on topics such as machines, camping and kitchen science.
