SATs practice children actually want to do.
Tiger Shark turns Year 6 revision into something to look forward to — maths, grammar, spelling, reading and times-table games, a shark called Cosmo who cheers every right answer, and a progress report that tells you where to focus.
Made for Android phones and tablets. Built by a UK primary teacher to the national curriculum.
Everything Year 6 SATs is tested on
Five subjects, thousands of original questions, one friendly shark. Each quiz quietly learns what your child finds hard and serves more of it.
Arithmetic and reasoning with hands-on workspaces — set the clock, place the number, drag the angle.
Grammar and punctuation in real SATs question styles, every topic in the test framework.
Words read aloud in a clear British voice — a proper spoken spelling test, no adult needed.
Over 200 original passages — biography, science, fiction and poetry — with SATs-style questions.
Fast arcade games that target the facts each child finds hardest.
Meet Cosmo — and his room
Every correct answer earns a fish. Fish buy hats, glasses, things to hold and pets — and Cosmo wears them on the home screen, every day.
He's on the home screen, wearing whatever they chose
Cosmo greets your child by name, blinks, follows their finger, and surfaces to cheer each right answer in a quiz. What he's wearing — and who's swimming next to him — is up to them.
- Ten hats, five pairs of eyewear, seven things to hold
- Six pets: a porcupinefish, an electric eel, a walrus, a sea otter, a hermit crab and a humpback whale
- Each child on the device gets their own Cosmo
The shop on the island
Tap anything to try it on before buying. A few things are free from the first day, so there is always something to wear; the rest cost fish. Once something is owned, swapping is free for ever.
Prices are set so that a good day's practice — about twenty right answers — is about twenty fish. Nothing is bought with real money, and there is nothing to unlock with it either.
1 fishper correct answer
Across every quiz and game. The count sits on the home screen next to their name.
days in a row
One short session keeps it going. Missing a day resets it — which is the point.
Cosmo surfaces on a right answer
Wrong answers get a quiet "not quite" and the correct answer — no jingle, no penalty.
A report you can read in a minute
The progress page is written for adults: a score guide per subject, a fortnight of practice history, and every topic graded so you know where to spend revision time.
What it tells you
Score guides use the same 80–120 scale as the real SATs, with the same two bars:
Each topic is graded on evidence from recent practice:
A score only appears once there is enough evidence across enough topics to be fair, and it sharpens as more questions are answered. It is a guide from practice in the app — not a prediction, and not a SATs result.
The practice history shows which days were practised and in what, so "I did loads" and "I did one set on Tuesday" are easy to tell apart.
Built for families, not for data

Made to be read
Larger text, a high-contrast scheme and a reduced-motion option, one tap from the home screen. Several children can share a device, each with their own progress, fish and Cosmo.
