Train what you can actually measure.
Five minutes a day of short games that adapt to you. Every game tells you how strong the evidence behind it is, and a monthly check-up shows whether anything really changed.
Free. No ads. Works offline. The daily challenge needs no account.
What five minutes looks like
Each day you get three games, picked so every skill comes up at least once every three days and your weakest skill comes up most.
0:00
Flash
Catch where the dot flashed. It gets faster as you do.
1:30
Math Sprint
Sixty seconds of mental arithmetic at your level.
3:00
Color Clash
Name the ink, not the word.
4:45
Done for today
No streak to protect. Come back tomorrow, or don't. It'll adapt either way.
Twenty-one games in seven areas, labeled honestly
Getting better at a game mostly makes you better at that game. So instead of promising a sharper brain, each game says plainly what the research supports.
Flash
Speed
Modeled on the speed-of-processing task from the ACTIVE trial, the best-studied brain training there is.
Speed Match
Speed
A quick same-or-different call. You'll get faster at it; whether that carries over elsewhere is unclear.
Odd One Out
Speed
Visual search, a basic part of processing speed. You'll scan faster in games like this; everyday effects aren't proven.
N-Back
Memory
You'll get better at holding things in mind on tasks like this. Wider benefits are debated.
Recall
Memory
Holding a pattern in mind for a moment. Gains mostly stay with similar memory tasks.
Pairs
Memory
Remembering what was where, the kind of memory you use every day. You'll get better at this game; wider memory gains are unproven.
Color Clash
Attention
Trains you to ignore a strong distraction. Improvements mostly stay with similar tasks.
Arrows
Attention
The classic flanker task from attention research. Trains ignoring nearby distractions; benefits stay close to the task.
Watch
Attention
Modeled on the SART, a lab test of sustained attention. You'll get better at not tapping on autopilot; benefits beyond the task are unclear.
Drift
Flexibility
Switching between two rules is a well-studied skill. You'll get quicker at switching; wider effects are debated.
Switch
Flexibility
Task switching, as studied in labs. Practice cuts the cost of switching on tasks like this one.
Sort
Flexibility
Based on the Wisconsin Card Sort, a classic test of flexible thinking. Practice helps you catch rule changes in this game; wider benefits are unproven.
Sequence
Problem Solving
No good evidence it trains anything beyond puzzles. It's here because variety keeps the habit fun.
Balance
Problem Solving
A logic puzzle. Fun and a little taxing, with no evidence it trains anything wider.
Tower
Problem Solving
Based on the Tower of London, a standard test of planning. Practice makes puzzles like it easier; broader effects aren't established.
Math Sprint
Math
Practice mental arithmetic and you get faster at mental arithmetic. Simple, and useful at the checkout.
Bigger
Math
Quick number sense with real arithmetic. Practice makes everyday comparisons faster.
More Dots
Math
Trains the gut sense for quantity that math builds on. Practice sharpens it; whether that improves math skills is debated.
Rotate
Spatial
Mental rotation is one of the best-studied spatial skills, and practice reliably makes it faster. Whether that carries over to other tasks is less clear.
Fold
Spatial
Paper folding is a classic test of spatial visualization. Practice helps with puzzles like it; there's no evidence it does more.
Route
Spatial
Keeping track of where you are and which way you face, in your head. Good practice for that, with no evidence it improves real-world navigation.
Built differently on purpose
| Topic | MindHone | A typical brain-training app |
|---|---|---|
| Ads | None, ever | Video ads between games |
| Daily pressure | “4 of 7 days this week” | Streaks you can lose, push notifications |
| Claims | Straight talk about what each game does | “Boost your IQ” |
| Progress | A monthly check-up at fixed difficulty | Points that only go up |
| Offline | Every game works offline | Needs a connection |
| Accessibility | Larger text, color-blind palettes, reduced motion, keyboard play | Small type, fixed colors |
Questions
Is it free?
Yes. Every game, the daily session and the check-up are free. No ads, no trial that turns into a subscription.
Will it make me smarter?
Probably not in the general sense, and we don't claim it will. You'll get measurably better at the skills you train. One of them, processing speed, has unusually strong evidence for everyday benefits, mostly in adults over 65.
How long does it take?
About five minutes a day. Three short games, then you're done. Rest days are fine.
I'm not fast. Is this for me?
Yes. Every game starts easy and adapts to you, so the pace follows your level, not anyone else's.
What do you do with my data?
We store your email, name and game results to show your progress. Nothing is sold or shared. Download it or delete your account from Settings at any time.
Start with a three-minute check-up.
It sets your starting point. Then five minutes a day, and in a month you can compare check-ups and see what actually changed.
