## What is Polyrium?

Binarium - Be Smart is a premium offline spaced repetition app that helps you memorize information for a long period of time with minimal effort. The app is based on the proven SM-2 algorithm, which calculates the ideal time to review each book, so you spend less time studying and remember more. Cards can be organized into packs and sub-packs, quickly combined, duplicated, archived and customized to suit your personal learning system. 

Binarium supports multiple study modes: Standard, Sprint, Typing, Cram and a calm bedtime review for evening review without overloading. The easy-to-use editor lets you manually create books, bulk import text from the clipboard, use cloze deletion, and use cue templates for deeper learning. Detailed statistics show retention curves, a 30-day repeat forecast, streaks, records and overall progress. The algorithm can be flexibly customized through intensity presets, repetition limits, reminders, themes and interface settings. The text-to-speech function built into the device reads books aloud in a natural voice, making it particularly convenient for hands-free practice and language learning.

Binarium - Be Smart turns daily repetition into a calm habit that gradually accumulates into real knowledge.
