# Neuraknow

> Neuraknow is a free spaced-repetition app for iOS and Android, built around the FSRS (Free Spaced Repetition Scheduler) algorithm. It helps people remember what they learn by scheduling reviews just before they would otherwise forget. All data stays on the user's device — no account, no cloud, no tracking, no ads.

Neuraknow is built by Abid Waqar, an independent developer. It is a personal project, built with Flutter, distributed free on the App Store and Google Play. The product is positioned as the lowest-friction way to apply spaced repetition daily, for people who want the science without the setup tax of configuring Anki.
