What is Spaced Repetition (SRS) and why does it work?

Spaced repetition is a cognitive learning method based on the Ebbinghaus forgetting curve. Engram schedules review sessions right at the point when your brain is about to forget an expression, achieving maximum retention with minimal effort.

Is Engram free to use?

Yes! Engram provides a feature-complete free tier with core decks, swiping, dictation, and native audio. Upgrading to Engram Pro unlocks all card skins, custom deck building, widgets, and iCloud sync.

Will my progress sync across devices?

With iCloud enabled, your study progress syncs seamlessly across all iOS and iPadOS devices signed into the same Apple ID.

Is Engram suitable for IELTS, TOEFL, or business English?

Absolutely. Engram includes dedicated decks for IELTS, TOEFL, SAT, GRE, and business English with authentic example sentences and dictation practice.

MEMORY SCIENCE

Smart SRS Scheduling,
Beat the Forgetting Curve

Engram incorporates an enhanced Spaced Repetition System based on cognitive memory retention. As you swipe cards, the algorithm dynamically calculates your memory decay interval and schedules reviews precisely when your brain needs reinforcement.

SRS Long-Term Retention (>90% Memory Saved)

By scheduling micro-reviews on critical interval days (D1, D3, D7, D15, D30), decay is drastically slowed down, solidifying phrases into permanent long-term memory.

Retention Rate Over Time (%)Observation Period: 30 Days
