Count every key you press.

One number — keys pressed — sounds trivial until it runs for months. A heavy day is well past 50,000 keystrokes. Counted continuously, that volume stops being trivia and becomes a record of how you actually work, broken down by the things that vary: which key, which app, which keyboard.

Per key, per app, per keyboard

The same hands behave differently depending on context. You hammer the arrow keys in a spreadsheet and barely touch them in a chat window; your count climbs three times faster in your editor than in your inbox. Splitting the total by app shows where your day really goes, and splitting it by keyboard tells you whether the external board you bought is pulling its weight. The shape of the total is the statistic that matters, not the total itself.

From a count to a map

Counting answers how much. The next question is where. Tally every press by key and the flat number becomes a heatmap — space and E glowing dark, your pinkies barely registering, the keys you fumble tinted red. Same data, read spatially: the count is the raw material, the map is what you read.

Counts that, never what

This only works because the scope is narrow on purpose. Pulse records that a key was pressed and when — never the letter, the word or the password behind it. The count is real; the content never leaves your fingers. Everything stays in a local database on your Mac, which is what lets it run all day without watching what you write.
