The features

Every feature is here to stop one thing: re-typing Friday's misses.

Spellimus is built around a simple loop — listen, type, review, master. Everything below exists to make that loop kinder, smarter and more honest than a paper list.

Adaptive practice

The words they keep missing get the most attention — automatically.

Every attempt is scored on correctness, speed, and whether it took a hint. The engine quietly weights practice toward the words your child struggles with, and lets mastered words rest.

  • Per-word correct/incorrect, speed, hint use
  • Mastery threshold (3–5 correct, unaided) — tutor's call
  • Review mode pulls forward struggling words across all sources

Weekly list builder

Paste the list from school — or pull it straight from the curriculum library.

Teachers build a list once; parents can import by pasting, photographing the school newsletter, or scanning a QR code the teacher shared. 20-word cap keeps it reasonable.

  • Four import paths: paste, photo OCR, library, QR
  • Auto-detects UK/US year-level patterns
  • Schedule lists a term ahead; auto-rollover each Monday
Tutor dashboard

One glance, and you know what your kid actually struggled with.

No streak guilt. No dashboards full of vanity numbers. Just the words that need another look, and a single 'send a nudge' button for the days motivation dips.

  • Per-child word history with source tags
  • Weekly digest email — opt-in, one page, takes 20 seconds to read
  • 'Master last year's misses' objective with one click

Audio & voices

Hear it once, hear it slower, hear it in a sentence.

High-quality neural voices across UK and US English — or record your own. Familiar voices help, especially for younger readers and EAL students.

  • Six neural voices across UK/US English
  • Word, sentence, slow-mode, and phoneme-by-phoneme
  • Record-your-own — great for tricky names and homophones
Curriculum library

Real curricula, not a generic word soup.

Common lists organised into packs you can pull in or remix: UK Year 1–6, US Grades K–5 (Fry, Dolch), phonics stages, and topic packs teachers have built for their classes.

  • 200+ curated packs, all authored by practising teachers
  • Filter by age, region, phonics stage, or common error
  • Publish your own packs — optional, for teachers and tutors

Mobile · iOS & Android

The practice session was made for the back of a car.

Kids practise wherever they are — school bus, grandparents', couch. A session is six minutes. The native keyboard sits right under the spelling boxes.

  • Native iOS and Android — not a wrapped webview
  • Offline practice for 7 days. Syncs back when online.
  • No ads, no in-app purchases, parent PIN on settings
Groups & invites

One link. The whole class joins without a CSV in sight.

A group is a reusable audience — your child's Year 5 class, your Saturday tuition cohort, a homeschool co-op. Parents join via link or QR; teachers see attendance and progress on assigned lists.

  • Parent-led or teacher-led — both modes respected
  • Printable QR codes & PDF join sheets for parents' evening
  • Unlimited co-organisers (TAs, grandparents, tutors)

Weekly exam mode

A proper, silent end-of-week test. No hints, no do-overs.

Schools asked for it, so we built it. On exam day, kids do a 20-word run through with no retries, and the tutor sees a clean results page afterward — the same one you'd get from a paper test.

  • Silent mode: no hints, no second listen, no visual feedback
  • Auto-carries missed words forward to next week's practice
  • Printable results sheet — looks like a real class test
