01
You open the app
Your first Cognilo puzzle starts straight away. No email, no password, no "tell us your goals" questionnaire. That isn't a trial screen; it is simply how the free tier works.
No form is the fastest way to a first puzzle.
Is there a brain training app without an account?
Yes: Cognilo starts your first puzzle with no sign-up and keeps your history on your device, while Lumosity's free play and the free version of The Mind Company's skills app both require an account, according to their own pages checked in November 2026. We make Cognilo, so weigh our word accordingly; every competitor fact below links to the competitor's own page.

Five rounds, about six minutes
The Daily 5 picks five short games for your level from six categories: memory, focus, logic, numbers, spatial and language. Each day plays five of the six and rotates, so all six come round across the week. It is untimed by default; Sprint adds a clock and Zen turns ratings off.
03
Where your results go
Nowhere, unless you opt into Game Center. The listing describes Cognilo as local-first: no account, no ads and no tracking, with history kept on your device. With no account to sync through, the JSON export is your backup when you change phones.
04
What still needs the internet
Buying or restoring Cognilo Pro, and optional Game Center leaderboards. Competition is off by default, so if you never switch it on, the daily puzzles stay offline.
05
What the others ask for
Lumosity's help center says free users can play 3 games a day "as long as you have an account with us" (Lumosity). The Mind Company lists the free version of its reading, writing and math app as requiring a free account (The Mind Company). Neither is unusual: an account is how many apps tie progress to a person rather than a phone. Cognilo ties it to the phone.
An account ties progress to you. No account keeps it on your phone. Pick the one you value.
No-account brain training: questions
Is there a brain training app that doesn't need an account?
Yes. Cognilo, which we make, starts your first puzzle with no sign-up and no questionnaire, and keeps your history on your device. Lumosity and The Mind Company's skills app both ask for an account to use their free versions, according to their own pages checked November 2026.
Can I play Lumosity without an account?
Not the free version, by Lumosity's own help page: "As a free user you can play 3 games per day as long as you have an account with us" (Lumosity help center).
Do other big brain apps need an account?
The ones we checked do. The Mind Company's reading, writing and math training app lists its free version as requiring a free account, with one three-game workout a day and a weekly featured game (The Mind Company, checked November 2026).
Where does Cognilo keep my results?
On your device. The listing describes Cognilo as local-first, with no account, no ads and no tracking, and lets you export your history as JSON at any time.
Does a no-account brain app work offline?
Cognilo does. Purchases, restoring purchases and optional Game Center leaderboards need a connection; competition is off by default.
Will brain games improve my memory?
Expect to get better at the games. The National Institute on Aging says there isn't enough evidence that commercial brain-training apps have the effects seen in research training programs (NIA, reviewed 2024). Cognilo's own ratings describe how you play its puzzles, not intelligence or health.
How to try it without giving anything away, in 3 steps
- Install and play. The first puzzle starts at once. If a paywall appears, Continue Free closes it without buying.
- Leave competition off. It is off by default; Game Center leaderboards are optional and are the only social feature.
- Export now and then. Cognilo lets you export your history as JSON at any time, which is your copy if you switch phones.
A design decision we made: ratings only move when several sessions agree, so one tired evening doesn't rewrite your profile. That matters more when there's no cloud account averaging things out across devices.
Who Cognilo is not for
If you play on an iPhone and an iPad and want one shared progress history, Cognilo's on-device history won't do that, and an account-based app is the likelier fit. If you want 40-plus games, Lumosity and The Mind Company's app both list more than Cognilo's eight puzzle types. If you want reading, writing and speaking practice in particular, The Mind Company's app is built around those skills. And if you want no screen at all, a paper puzzle book needs no account either.
