Math practice for journalists.
A reporter who pipes every figure to AI loses the gut check that catches the implausible number in a dataset.
Is math practice useful for journalists?
Data journalism and beat reporting both run on numbers a reporter is supposed to sanity-check before publishing. Increasingly the spreadsheet work and the percentage math go straight to an AI tool. The problem is the silent one: when you never estimate, you lose the gut feel that says this figure cannot be right before you have even worked it out. A press release claims a 400% rise; a quick mental estimate says that is impossible given the base. Senwitt math reps keep that fast, approximate number-sense in regular use.
A math rep, for journalists
A rep asks you to estimate, in your head, whether a claimed percentage change is plausible given two raw figures — no calculator. Then it has you check a quick ratio or per-capita rate. It is the exact reflex you need when a source hands you a stat and you have ninety seconds to decide whether it smells wrong before you quote it.

How the habit fits a journalists day
Run a math Set as a warm-up before you open a dataset or a budget document. Seven minutes of mental arithmetic and estimation gets your number-sense active, so when the first figure of the day lands you can size it up in your head rather than reaching for the calculator and trusting whatever it returns.
Questions journalists ask
- I am not a data journalist. Why would I need this? Because every reporter quotes numbers — turnout, budgets, percentages, polls — and a wrong one is a correction or worse. Estimation is the cheap defense: knowing roughly what the answer should be so an implausible figure jumps out. Senwitt keeps that quick mental check in practice for any beat.
- Does it cover statistics like margins of error? The reps focus on arithmetic, estimation, and numerical reasoning — the everyday number-sense behind sizing up a claim. They are not a stats course on confidence intervals. But the habit of approximating and reasoning about figures by hand is the foundation that makes a stats claim easier to interrogate.
- Will it make me better with numbers? We do not promise that. Senwitt is practice, not a claim about your numeracy. It keeps you doing quick mental math and estimation regularly instead of routing every figure through a tool. Whether your reporting gets a sturdier number-sense from it is your judgment to make.

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.
