Spelling Test

Read full description

Practice for the next school spelling test with the words your child actually needs to learn. Add the class list, then let your child listen, write, replay and check at their own pace—without you reading every word aloud. NATURAL VOICES, LESS PARENT DICTATION Natural-sounding AI voices read your list aloud. Replay a tricky word whenever needed. Use paper and pencil with iPhone, or write in the app on iPad. Speech is AI-generated, not human recordings. UNDERSTAND WHAT YOU HEAR Optional context hints read a short meaning or example with the word. Practise in 12 languages; the interface follows your device language. Change the practice language manually when a short word is ambiguous. GIVE MISSED WORDS ANOTHER TRY Mark words you missed and keep them in the review list. Practise selected words again instead of repeating everything. Save school lists for the next homework session. LISTEN, WRITE, CHECK On iPhone, listen and write in an exercise book or on paper. Replay a word when needed, move to the next word when ready, and reveal the answer to check your work. On iPad, you can also write in the app with Apple Pencil or your finger; optional trace letters provide a guide. BRING YOUR SCHOOL WORDS Type a teacher’s word list or use photo scanning to bring words into practice. Check the recognised text before starting, and save custom lists to use again. Spelling homework should not have to wait until someone is free to read the words aloud. Spell-Up helps school-age students practise listening and writing independently, using the words they actually need for class. Designed for students and families building an independent homework routine—not a replacement for teaching or a guaranteed improvement in grades. Photo recognition and voice availability vary by language and device. Includes a limited trial; continued access requires a purchase. WORD LISTS FOR SCHOOL PRACTICE Bring the exact words assigned at school, save your own lists, or choose from the built-in collections. The English library includes Dolch sight words, Fry high-frequency words, grade-based spelling collections and themed lists. Practice is available in 12 languages, so students can also use word lists in another supported school language. Built-in levels and lists are practice resources, not official curriculum-matched textbook editions.
