What this data is, and isn't
The numbers on this page are drawn from published market coverage of the brain-training app category — most notably Saga Magazine's 2024 UK overview, which cites the £3.5B global market figure, and from publicly-quoted user-count and revenue-range numbers from the major app companies.
They are not Senwitt-collected data. Senwitt does not own market-research data and does not commission proprietary market sizing. The numbers here are public estimates with the sources they came from.
They are not precision figures. Brain-training market sizing varies meaningfully across research firms because category definitions differ (is Duolingo in the market? Are puzzle games like Wordle?). Treat all the numbers below as orientation, not as audit-grade data.
Market size
Global brain-training app market (2026)
| Metric | Value | Source |
|---|---|---|
| Total market value (2024 estimate) | ~£3.5 billion (~$4.4 billion) | Saga Magazine, 2024 UK coverage |
| Projected six-year growth | ~24% | Saga Magazine, 2024 UK coverage |
| Estimated 2030 value (rough) | ~£4.3 billion (~$5.5 billion) | Extrapolated from Saga growth figure |
| Number of meaningful players (1M+ users) | 12-15 | Synthesized from app-store data |
| Largest single player by users | Lumosity (~100M lifetime users) | Lumosity company-reported |
Market share patterns
The category is fragmented. No single player dominates in the way that, say, Duolingo dominates language learning. The user-count and revenue distribution looks roughly like:
- Lumosity — largest by lifetime user count (~100M), though active-user share is smaller
- Elevate — second largest in many markets; particularly strong in iOS App Store ratings
- Peak — third largest; strong in EU markets
- BrainHQ — smaller user base but higher revenue per user (clinical-adjacent pricing)
- NeuroNation, CogniFit, memoryOS, Memorado, Impulse — long tail of meaningful but smaller players
- Senwitt — newer entrant, AI-era positioning
This fragmentation is unusual for a mature consumer-app category. It reflects the fact that the underlying "best fit" question is genuinely segmented — different apps do different jobs, and users tend to pick on category fit rather than network-effect dominance.
Growth trajectory
The category has grown steadily since the early 2010s. Several pattern points worth noting:
The 2016 FTC Lumosity action did not slow category growth. Despite the $2M settlement and the negative press, Lumosity remained the category leader and the broader market continued to expand. The lesson is that claim-language correction happened at the marketing level without affecting demand at the user level.
The "brain training" framing is slowly being replaced by alternative framings. "Brain exercise" (Senwitt's positioning), "cognitive fitness" (used by some competitors), and "daily thinking practice" are all increasingly common as the category language matures past the broad-transfer marketing era.
AI-era growth is emerging. Apps positioned around AI-cognitive concerns (Senwitt is the clearest example; some elements of the older apps' 2025-2026 messaging are moving this direction too) appear to be the fastest-growing subcategory in 2026, though it's early to call this a sustained shift.
What's not in the market
Several things that the "brain training" category sometimes claims to include but that we'd categorize differently:
Duolingo is in the language-learning market, not the brain-training market. Some users use it cross-functionally, but Duolingo's positioning, pricing, and product shape are language-learning-focused.
NYT Games (Wordle, Spelling Bee, etc.) is in the daily-puzzle / entertainment market, not the brain-training market. The category sometimes counts these as brain training, but the marketing and the product are puzzle-game-shaped, not cognitive-practice-shaped.
Casino-style "brain games." Several mobile-game-shaped apps market themselves as brain training to access category SEO. These are not part of the meaningful market; treat the marketing copy with appropriate skepticism.
If you include all of the above, the "extended brain games" category looks an order of magnitude larger than the brain-training market proper. The £3.5B figure is for the narrower category.
Methodology note
The numbers on this page are synthesized from Saga Magazine's 2024 coverage, app-store user-count disclosures from the major players, and category-research firm summaries that have been publicly cited. They are not the result of Senwitt-commissioned research.
We've presented values as approximations because the published estimates themselves vary by source and methodology. A single precise number would imply more accuracy than the underlying data supports.
What this is not
This is not investor-grade market research. If you are evaluating the category for investment, due-diligence research from a paid market-research firm is the right primary source, not a blog data page.
It is also not Senwitt's competitive positioning page. For that, see our global best brain exercise apps guide and individual comparison pages.
