Attention is a trainable mechanic. mindima gives you short drills for it and shows which sessions held.
Free to start. Play before you sign up.
The mechanics behind a deep-work block.
One short warm-up. Before the work, not instead of it.
Selective attention
Picking the signal out of the noise when a notification competes.
Sustained attention
Holding one target over minutes, not seconds.
Working memory
Holding the thread of an argument while you act on it.
Take a turn before you decide.
Ten measured tests, right here. No download, no sign-up.
Attention Filter
Not measured yetHow well you ignore the wrong answer when it is louder than the right one.
Selective attention under conflict, the Stroop effect. Reading is automatic, so the word interferes with naming the ink, and your score is how well you suppress the automatic answer.
Every score is placed on a reference distribution. Open Attention Filter on its own page or see all ten.
One session becomes a daily habit.
The charts show whether it is holding. Signals, not a scoreboard.
Streaks build the habit
Close the ring one day at a time.
Mastery marks real skill
Badges like Memory Master are weekly titles earned with accuracy, never bought.
Progress stays visible
Your charts show which sessions line up with your best focus and mood days.
Why these mechanics work is on the science page.
Fair questions.
When should I train, before deep work or during a break?
Use it as a warm-up: five minutes to settle selective and sustained attention before you start, rather than as a break in the middle.
