What Is LetterFlow?
LetterFlow is a handwriting practice tool designed for children who are learning to form letters correctly. It is grounded in evidence-based handwriting instruction and provides structured, research-backed practice in a fun and engaging format.
The app is ideal for occupational therapy sessions, handwriting intervention programs, classroom practice, tutoring, and at-home use. It works on any desktop or laptop computer and requires no download or installation.
How This Handwriting App Works
LetterFlow guides children through three progressive levels of handwriting practice:
- Watch and Learn — The child watches an animated demonstration of correct letter formation with spoken stroke cues guiding every movement.
- Trace — The child traces the letter with fading guidance over multiple repetitions, building the muscle memory needed for independent handwriting.
- Free Write — The child writes the letter independently. The app checks letter size and placement in real time and gives immediate feedback.

The Research Behind LetterFlow
LetterFlow is built on evidence-based handwriting instruction principles. Research consistently shows that explicit, multisensory handwriting instruction — combining visual models, verbal cues, and physical practice — produces the strongest outcomes for children learning to write. LetterFlow brings all three of those elements together in a single, easy-to-use tool.
