Do Brain Training Apps Work? What the Evidence Supports
An honest read on brain training claims: what practice reliably improves, what it does not transfer to, and what regulators have said about the marketing.

The brain-training industry made a large promise — that playing games would make you broadly smarter — and the evidence did not support it. What the evidence does support is narrower and more useful: you get better at the thing you practise, and that improvement transfers only weakly, if at all, to tasks that look different.
That is not a reason to stop practising. It is a reason to practise deliberately. If you want to be faster at arithmetic, drill arithmetic. If you want to hold more in working memory during a task, train that task. The honest framing makes the activity more useful, not less, because it points you at practice that matches the thing you actually want to improve.
These articles cover routine design, session length, difficulty progression, how to read a score history without fooling yourself, and what the major studies and regulatory findings actually said.
The cornerstone article covers the far-transfer problem and the regulatory action taken against overclaiming. It sets the expectations everything else here assumes.
Short and frequent beats long and occasional, mostly because it survives contact with a normal week. The routine articles cover what that looks like in practice.
Early score gains are largely task familiarity. The progress-tracking articles cover how to tell learning from warm-up.
An honest read on brain training claims: what practice reliably improves, what it does not transfer to, and what regulators have said about the marketing.
The four dials that decide whether a timed drill is usable: an untimed alternative, adjustable reveal speed, a difficulty floor, and no single-sense dependency.
Speed and accuracy trade against each other, so training them in the wrong order makes you fast at a method that does not work. Here is the order and the test.
What systematic reviews actually found about computerised brain training in later life, and the four design features that decide whether a drill is usable.
How two or three people share a brain game that has no multiplayer: pass-the-device turns, matched difficulty, and the one genuinely shared artefact.
A capability comparison built only from each publisher's own pages, read 21 September 2026 (ours re-read 2 October) — including where ours is the wrong choice.
A ten-minute practice route for adults with no spare time: one timed sprint, one accuracy set, one technique and one memory round, plus the honest limits.
Nine claims people repeat about brain games, each answered briefly with what the evidence actually says and what a practice app does and does not do.
A selection rule with a number attached, plus what a difficulty label physically changes in an arithmetic drill and in a memory round.
How a date-seeded daily challenge works, why everyone gets the same one, what a once-a-day cap is protecting, and where the format stops being useful.
Deliberate practice needs a specific target, immediate feedback, difficulty just above your level, and correction. Here is how that maps onto a short drill.
Five to fifteen minutes covers most practice sessions. Here is the evidence on dose, why long sessions stop paying, and how to build one from short drills.
Most practice records flatter you. Hold the mode and difficulty fixed, read accuracy before score, use the median time, and run one cold check each week.
Blocked practice groups one problem type together; interleaved practice mixes them. Mixing usually feels worse during the session and tests better afterwards.
What offline means for a practice app specifically: whether streaks, personal bests and adaptive difficulty survive without a connection, and what stops.
Answer times are skewed, so the average is pulled up by a single long think. Here is what mean, median, fastest and consistency each tell you about a session.
A short drill used as a start ritual, not a cognitive enhancer: why the hard part is beginning, and what five minutes of arithmetic is actually doing.
Paywalls here usually gate catalogue access, session choice and reports rather than a different kind of exercise. No prices, just the structure to check.
A flat practice score has four common causes, and they need different fixes. Here is how to read your own accuracy and timing record to tell them apart.
Why short daily practice beats long occasional sessions, how to design a minimum you can always hit, and what streaks are actually good and bad at.
