Math practice for researchers.
Letting the model run the back-of-envelope check means you stop noticing when a reported effect size is simply implausible.
Is math practice useful for researchers?
Quantitative judgment in research is mostly fast sanity-checking: is that effect size plausible, does that p-value square with that sample, is the percentage even arithmetically possible. AI now does the figures and the stats narrative, so the estimation reflex, the one that flags a number that cannot be right before you read further, gets little exercise. Math practice in Senwitt is mental arithmetic, estimation, and order-of-magnitude reasoning, the rough-check instinct a researcher uses to catch a result that does not add up.
A math rep, for researchers
A short item asks you to estimate whether a stated quantity is in the right ballpark, no calculator, the way you would glance at a table and think that mean cannot be right given that range. You either feel the number is off or you do not. It is the reflex that makes you re-read a methods section instead of trusting a figure.
What math practice covers in Senwitt

- Pattern recognition
- Quick approximation

How the habit fits a researchers day
Run the math Set before a stats-heavy reading session or before you review a colleague's numbers. Seven minutes of estimation by hand wakes the part of you that questions a figure on sight, so when the AI-generated table looks clean you still feel the one cell that is quietly wrong before you cite it.
Questions researchers ask
- I do not do quantitative research, is this useful? Possibly less central for you, which is why reading and reasoning are the recommended skills for researchers. But estimation and number-sense help anyone evaluating quantitative claims in a paper. If your field is purely qualitative, you may weight math lower in your daily Set, and that is a supported choice.
- Is this real statistics practice? No. Senwitt practices mental arithmetic, estimation, and approximation, not statistical methods or analysis. It will not replace your stats training or your software. Think of it as the rough sanity-check instinct that runs before formal analysis, kept in regular use, rather than a course in statistics.
- Can the model not just check my numbers? It can, and often should. The point of the math Set is not to compete with that. It is to keep your own estimation reflex alive, so you notice when the model's clean output is wrong, which it sometimes is. The reps are a counterweight to fully outsourced number-checking.

Not brain training. Brain exercise.
Senwitt is a daily brain exercise app, not a brain training program. We do not claim to improve general cognition, prevent cognitive decline, or treat any condition. Independent scientific consensus — the 2014 Stanford Center on Longevity / Max Planck Institute statement signed by 70 neuroscientists, the 2016 Simons et al. review in Psychological Science in the Public Interest, and the FTC's 2016 settlement with Lumos Labs — has concluded that “brain training” claims are not supported by the evidence. Senwitt is built on a different premise: skills you actively practice get sharper; skills you stop practicing fade.
