SparkSave helps children and young people understand how money works — and build habits that last a lifetime. Lumi guides every lesson. He explains one idea at a time, with everyday examples, and a quiz at the end helps it stick. There are 120 lessons across four tracks that grow with your child. A track for every stage - Under 7 — what money is, saving, waiting and choosing. Fully narrated, for children who can't read yet. - 7-10 — budgeting, comparing prices, advertising and in-game purchases. - 11-15 — interest, inflation, bank accounts, online safety and first steps in investing. - 16+ — pay, tax, credit, renting and retirement, based on Portuguese rules. Dream Bank Your child picks a real goal with you: a bike, a day out, a book. You set the tasks to get there — helping at home, finishing lessons, scoring well on a quiz — and a progress bar shows how close the dream is. The final say is always yours. Lumi and his accessories Every lesson completed earns coins to unlock accessories for Lumi, who then wears them throughout the app. Coins are virtual and never involve real money. For parents - Parents menu protected by a code - Choose the age group and the Dream Bank tasks - Under 7 lessons available offline - Portuguese and English - Optional account, to back up progress and continue on another device Privacy No ads and no in-app purchases. We collect as little as possible: your child's name stays on the device only. SparkSave is educational and does not provide financial advice.
