## What is Brain Training Palace?

Entora is brain training for people who want to know WHAT they're training — and WHY.
  
  No "+5 IQ." No "get smarter overnight." Instead: 9 science-backed cognitive modules, a different exercise every session, each with an
  honest note on what the research actually shows.
  
  Perfect for students, language learners, aspiring mnemonists, and anyone who wants to actively train their mind instead of passively
  scrolling.
  
  — 9 SCIENCE-BACKED MODULES —
  
  - Method of Loci — the technique used by the world's top mnemonists. Three variants: words, numbers, cards (Dresler et al., 2017,
  Neuron).
  - Speed of Processing — UFOV, Schulte Table, 4-Choice Reaction Time (Edwards, 2017, ACTIVE trial).
  - Attention — Stroop, Eriksen Flanker, Number Stroop: three classic conflict paradigms.
  - Dual N-Back — Visual + Audio N-Back with adaptive difficulty (3-down/1-up staircase).
  - Visual Patterns — Corsi Block-Tapping (Cambridge CANTAB).
  - Flexibility — Trail Making A + B (Reitan, 1958).
  - Number Recall — Forward + Backward Digit Span (Wechsler) plus the Major System mnemonic (Bower, 1970).
  - Spaced Repetition — your own decks with FSRS-light scheduling and cloze cards.
  - Active Recall — cued recall per card, or a 3-minute free-recall brain-dump of a whole deck (Karpicke & Roediger, 2008).
  
  — WHAT MAKES ENTORA DIFFERENT —
  
  - A different variant every session, never monotonous (variability of practice — Schmidt & Bjork, 1992).
  - Honest science: each module shows what the research really says — including where transfer to everyday life is still disputed.
  - Streaks reward consistency, not performance — no performance anxiety.
  - A smart reminder learns your preferred training time, entirely on-device.
  - Zero ads. Fair, transparent pricing. One-tap cancel.
  
  — PREMIUM INCLUDES —

  Full training history and progress insights

  iCloud sync across all your devices
