Why most reading apps fail language learners

Common tools weren't designed with language acquisition in mind.

The Problem

  • Forced memorization without context — words don't stick
  • Subscription lock-in — your data held hostage
  • Cloud-only storage — no offline access, no privacy

LinguistReader Solution

  • Only show what matters — words above your level
  • Context-rich learning — words remembered with sentences
  • Your progress, your data — local-first, export anytime
  • Full offline support — read anywhere, privacy guaranteed

The Science Behind It

Linguist Paul Nation's research shows that 98% vocabulary coverage is the threshold for fluent reading.

The i+1 hypothesis suggests that language acquisition occurs when learners are exposed to input slightly above their current level—comprehensible, yet challenging enough to drive growth.
