Koodinorppa

Small dives, big skills

Free · Designed for iPad. Not verified for macOS.

Over 450 lessons, each opens with a short primer. A daily challenge, smart review, 16 achievements, and leagues from bronze to diamond. Start in under a minute. Five minutes a day. One dive at a time. Koodinorppa is a young Saimaa ringed seal — a rare freshwater seal found only in Finland — learning to code alongside you. A short lesson in the morning, the daily challenge in the evening, a streak that grows as long as you keep the rhythm. Small dives – big skills. WHAT YOU'LL LEARN • Swift – the language of iPhone, iPad and Apple Watch • HTML and CSS – the structure and style of every website • JavaScript – the same language that powers Discord, Figma and Spotify • Python – for AI, data science and the apps behind Instagram • Vibe coding – tell the AI what you want and turn it into working code Koodinorppa has over 450 lessons across five tracks – with new content added regularly. Every lesson opens with a short primer that explains the idea, then the exercises begin. If you get stuck, each task offers a hint that guides without giving away the answer. Question types include multiple choice, write code, line ordering, fill in the blank, and concept cards – no two lessons feel the same. WHY KOODINORPPA WORKS • The daily challenge rotates each morning – a fresh concept each day. Complete it for double XP • Smart review schedules practice automatically so knowledge sticks • The Practice Hub lets you earn hearts back by revisiting your mistakes • Your streak remembers: play every day and it grows. Skip a day and Koodinorppa naps until you return • Weekly tournament – compete for a global Top 100 finish • Leagues in cohorts of ten – bronze through diamond. Top three promote, bottom three relegate • 16 Game Center achievements – from your first lesson to a one-year streak • Progress syncs between iPhone and iPad via iCloud • Full VoiceOver, Dynamic Type and Reduce Motion support WHAT WE DON'T DO • No ads, no in-app purchases, no subscriptions • No tracking across ad networks • No accounts beyond your Apple ID • Never sell your data Koodinorppa is made by Koodisto Digital in Finland. By the shore of Lake Saimaa, with care. Sign in with Apple. Your first dive in under a minute.
