Tiger Shark turns KS2 SATs revision into games children look forward to. It adapts as your child plays, so questions get harder when they're ready and ease off when something's tricky. Short SATs-style tests in maths, English grammar, spelling and reading, plus times-table games, with instant feedback and a shark called Cosmo cheering every right answer.
Free. Made for Android phones and tablets.
Five subjects, thousands of original questions, one friendly shark.

Arithmetic and reasoning that learns your child's strengths and weaknesses, quietly serving more of what needs practice.

Grammar and punctuation in real SATs styles — and the more your child plays, the better it targets their tricky spots.

The app reads each word aloud in a clear British voice — a proper spoken spelling test, no adult needed — and adapts to the words your child finds hardest.

Hundreds of original passages: Ada Lovelace, Amelia Earhart, black holes, dinosaurs, Ancient Greece, glowing sea creatures — plus stories and poems.

Six fast arcade games that quietly target the facts each child finds hardest.
Every child arrives at Year 6 with different gaps. Tiger Shark finds them without anyone having to say so out loud.
No placement test, no quiz about what they can already do. The app simply asks the question a Year 6 child is expected to answer, and watches what happens.
Struggle with the Year 6 fractions question and the Year 5 one comes next — then Year 4, then Year 3, until the ground is firm. Nothing announces it. There is no "you got this wrong" screen and no level to be demoted from.
Once a topic is secure the app stops asking and moves the effort somewhere it is needed. A topic your child finds hard comes round several times more often than one they have already mastered.
34 skills are laddered this way across maths, from Year 3 to Year 6 — fractions, place value, measures, geometry and the rest.
Questions are generated fresh each time, not drawn from a fixed list — so the numbers below are floors, not ceilings.
Install once, revise anywhere — no connection needed, ever.
Nothing your child does ever leaves the device. That's the whole privacy policy, really.
Every question written to the national curriculum, the way it's actually taught in class.
The progress page turns practice into a simple picture: what's mastered, what needs work.
