Ortomania
An offline mobile app that helps children in grades 4–6 master Polish spelling through short exercises, rules explained in a child’s words and smart repetition.
- Nearly 600 words across 10 spelling categories, each verified against a Polish dictionary
- Works fully offline with no accounts, ads or tracking — progress never leaves the device
- One codebase for iOS and Android, with a light and a dark theme
01The challenge
Polish spelling (ó or u, rz or ż, ch or h, nasal vowels and soft consonants) is one of the hardest parts of primary school. Worksheets drill words without explaining why a spelling is right, and most learning apps add ads, accounts and tracking that parents don’t want around a ten-year-old. We wanted short, calm practice that teaches the rule behind each mistake and works anywhere, even without internet.
02What we built
Every exercise shows a word with one gap and two or three letter tiles, and only one answer makes a real word. A wrong answer immediately shows the spelling rule in a child’s words, together with a related form that proves it (stół → stoły), and the word comes back at the end of the session. A spaced-repetition schedule brings back the words a child struggles with and shows mastered ones less often, while the Progress tab shows what the child already knows and which rules to revisit. All content ships with the app and was checked against a Polish dictionary. There are no accounts, ads or analytics, and every link that leaves the app sits behind a parental gate.
