About

Fluency Lens

Features
Read full description

Fluency Lens gives parents a calm, repeatable way to capture an oral-reading snapshot, review every marked word themselves, and turn the result into a short next step. Guide a timed reading sample, confirm miscues and the final word manually, and review the full words-correct-per-minute calculation before saving. The first completed baseline, chronological history, first five-minute parent-led practice, and an optional recheck reminder remain available free. Fluency Lens Plus unlocks repeat checks, comparable WCPM and accuracy trends, up to four local reader profiles, and child-scoped progress PDF sharing. Original passages are included for Grades 1–5 starting points. Fluency Lens is a parent-guided practice utility. It does not record audio, diagnose a learning condition, or assign an official grade placement. Terms of Use (EULA): https://fluencylens.com/terms/ Privacy Policy: https://fluencylens.com/privacy/
