Spelling.School

For anyone who keeps missing the same words. You hear a word in a sentence, you type it, you press Enter. If you miss it, you see exactly which letters went wrong and the reason: a doubled s, -able or -ible, a silent letter. Then you type it again from memory, and the word comes back for review on a spaced-repetition schedule until you get it right every time.

There are no lists to make. The app finds the words you miss and keeps them. When you keep making the same kind of mistake, it names the pattern and gives you more words with it until the pattern stops happening.

A two-minute warm-up finds your level. Ten levels, from everyday words to competition words, with a meaning and an example sentence for every word, plus topic lists (spelling rules, IELTS and TOEFL, medical, legal, work) and your own words. No ads, no leaderboards, no lives.

Who it is for: English learners sitting IELTS or TOEFL, where a misspelled answer scores zero; adults who write at work and are tired of the red line; and children with a parent's family account.

Every account starts with 14 days of everything. After that, Free stays free forever: every review keeps coming, and you get 3 new words a day at your level. Pro is $15 a month or $95 a year and adds all ten levels, every list, and as many new words as you want. Local prices in several countries.
