Simple Letter Quest

LetterQuest turns handwriting practice into a joyful, guided adventure. With a finger or Apple Pencil, your child traces uppercase and lowercase letters β and once they've mastered the alphabet, simple three-letter words β while getting real, encouraging feedback on every stroke. HOW IT WORKS Each letter starts with a short animated demonstration showing exactly how it's formed, stroke by stroke. Then your child draws it themselves, guided by dotted stroke paths, numbered starting points, and clear baseline and height guides β the same visual cues real handwriting workbooks use. After every attempt, LetterQuest's four-signal scoring engine checks: β’ Stroke order & direction β did they start and move the right way? β’ Shape accuracy β does it look like the letter? β’ Proportions β does it sit correctly between the guide lines? β’ Smoothness β was it drawn steadily, not shaky or rushed? Instead of a single pass or fail grade, your child sees exactly what they did well and what to try next time, with warm, age-appropriate encouragement either way. A COMPLETE LEARNING PATH β’ 26 uppercase letters, then 26 lowercase letters, unlocked as your child progresses β’ Word practice mode with simple three-letter words (cat, dog, sun, and more) once the alphabet is complete β’ A Progress screen with achievement badges, best scores, and attempt history for every letter β’ Adjustable difficulty β Easy, Standard, or Challenge β so scoring can match your child's confidence as they grow β’ Optional alphabet packs β starting with Serbian Cyrillic β available as one-time purchases alongside the free English alphabet BUILT FOR FOCUS, NOT DISTRACTION There are no ads, no accounts, and no data collection of any kind. Every bit of progress stays private on your device. The English alphabet is free forever; additional alphabet packs are simple one-time purchases with no subscriptions. Sound effects and haptic feedback add delight and can be turned off individually in Settings if you prefer a quieter session. ACCESSIBLE BY DESIGN LetterQuest supports VoiceOver and Dynamic Type throughout, so children and parents using assistive technology or larger text sizes can use the app comfortably. Whether you're a parent supporting early handwriting at home or an educator looking for focused practice between lessons, LetterQuest gives children a patient, judgment-free space to build real handwriting confidence β one letter, one stroke, one word at a time. Designed for iPad and iPhone.
