Practice the thinking you actually use.

What a session is for

• Memory and recall

  Short retrieval, encoding, and an evening check. Spacing is a simple 1, 3, 7, and 30 day ladder.

  Better recall of practiced material is not evidence of a general change in memory.

• Sustained focus

  A short contract, a few minutes of returning attention, and a distraction log.

  These are workflow practices. They are not a treatment for attention disorders, and they do not prove a general change in attention.

• Processing speed

  Sort, extract, and decide on fresh examples. Time is secondary to accuracy.

  A faster practiced task is not faster thinking in general. Do not average different clocks into one speed score.

• Executive function

  Capture, choose up to three priorities, and review what actually happened.

  This supports a workflow. It is not a neuropsychological executive-function test, and it does not label a condition.

• Overall sharpness

  Optional context check, a gentle reset, and one small cognitive loop. Nothing here is a diagnosis.

  Energy, sleep, and a short practice stay separate. The app will not combine them into a single score.

What this app will not tell you

• It does not diagnose a medical condition.
• It does not rank intelligence or compare you with other people.
• It does not treat a score on a repeated exercise as proof of a broader change in thinking.
• Gains on material you practiced are not the same thing as a change in everyday life. Those are tracked separately, and they stay observational.

Private by default

• You type your own notes. The app does not read your calendar, mail, or meeting transcripts.
• Answer keys and journal entries are encrypted in the database.
• Optional notes about sleep or energy are off unless you turn them on.
• You can export your entries or erase the account.

Evidence behind the design

• Improving Students' Learning With Effective Learning Techniques

  Practice testing and distributed practice were rated high utility for remembering material that was studied.

  Supports retrieval and spacing for the content being learned. It does not show that this app changes memory in general.

• Effectiveness of exercise for improving cognition, memory and executive function

  An umbrella review found modest average associations for exercise, with substantial heterogeneity.

  Activity is a foundation outside the 15-minute session. Effects vary, and this app does not prescribe exercise.

• WHO guidelines on physical activity and sedentary behaviour

  Adults are encouraged toward regular aerobic activity and strength work, as appropriate to their situation.

  Shown as general guidance. It is not an individualized exercise plan.

• CDC: About Sleep

  Adults 18 to 60 are generally advised to get at least seven hours of sleep.

  Sleep is optional to log. Missed targets are not treated as failures.

• Memory Problems, Forgetfulness, and Aging

  Memory problems have many contributors, and some are treatable. Persistent problems deserve a professional conversation.

  Used only for the non-diagnostic safety note. The app does not screen for disease.

• US POINTER lifestyle trial

  A structured lifestyle program was studied in older adults. Generalizing those results to a healthy adult in midlife is uncertain.

  Included so the age limit of that evidence stays visible. It is not a claim about this product.

• Cognitive Training: A Field in Search of a Phenomenon

  Reviews limited evidence that brain-training gains transfer to untrained abilities.

  Reason for labeling speed and game-like tasks as task-specific.

• Implementation intention and prospective memory

  If-then plans have a research base for remembering intended actions. Results depend on context.

  Used for executive-function if-then plans and prospective memory cues.
