Brain Training Palace: Entora
N-Back, Recall & Mental Math
Free · In‑App Purchases · Designed for iPad. Not verified for macOS.
Honest, science-backed brain training. Train recall, focus, attention and processing speed across 9 modules — a different workout
every session. No ads, ever.
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.

Ratings & Reviews
- This app hasn’t received enough ratings or reviews to display an overview.
Four new exercises. Find your way through a maze whose map keeps turning. Catch a target sequence in a stream of digits. Judge which crowd is larger without counting. Hold two tasks at once.
Every exercise now says what is known about it — including one where the evidence is mixed, and we say so rather than leaving it out.
All existing exercises were rebuilt on one layout: a larger play area, clearer answers, and readable text on every colour. Two exercises that used to be premium are now free, and one of the new ones is free too.
You can also ask Siri for your brain score, your streak, or whether today's session is done.
