Is Keep Lucid actually free?

Truly Free
How free95/100
Value7/10
How these scores work
Free Score (0–100) follows a fixed rubric: cards up front, auto-billing, hard time cutoffs, withheld core features, and paying with your data or attention all deduct points. 90–100 truly free · 70–89 free forever · 45–69 squeezed · 15–44 trial mechanics · under 15 fake or gone. Value (0–10) is editorial: real-world worth of the free offering measured against its paid equivalent. Full rubric on the methodology page.

Yes. Daily games and tools for brain health, each tied to what the dementia research actually found — a speed-of-processing test, blood pressure and hearing tools, movement, and the fourteen modifiable risk factors. No account, no card, no paid tier.

What it’s worth

The commercial brain-training apps charge monthly for the same exercises and claim considerably more than the evidence supports.

What you get free

  • Fifteen games and daily tools, none locked
  • A speed-of-processing test, the trained task with the strongest evidence
  • Tools for the modifiable risk factors — blood pressure, hearing, movement
  • A reading feed of current research, each story opening on its publisher
  • No account, so nothing to hand over and nothing stored about you

In practice: the brain-health exercises with evidence behind them, free, with no account and nothing collected.

Drawbacks

  • Brain training is not a treatment, and no app should be read as one
  • No account means no sync — progress lives on the device you used
  • A small project, not a clinical programme

Also paywalled

  • Nothing. There is no paid tier.

The catch

The catch is in what this kind of thing can honestly claim rather than in what it costs. Speed-of-processing training is the one form of computerised brain training with trial evidence behind it for dementia risk; most of the category has none. The tools here are built around the published risk factors instead of around a score going up, which is the right way round and still not a medical intervention.

The smart play

  • The speed test is the part with research behind it — start there
  • The risk-factor tools matter more than the games; hearing and blood pressure are the big two
  • Install it from the browser if you want it on a phone — there is no app store step

Why the fourteen risk factors
The Lancet Commission on dementia prevention identifies a set of modifiable risk factors — hearing loss, high blood pressure, physical inactivity and others — that together account for a substantial share of dementia risk. Building tools around those rather than around puzzle scores is the difference between following the evidence and following the market.
Brain training, honestly
Most of this category sells the idea that practising a game makes you generally sharper, and the evidence for that transfer is weak. The exception is speed-of-processing training, where trial results have been more encouraging. A site that will not say so plainly is selling you something.

Checked: October 2026 · Verdict: Truly Free — no card, no account wall, no meaningful catch. use it and go.
