Key Recorder configuration window with two configured observation events. — Example configuration with two events. Screenshot of the earlier interface.

From observation to CSV, in three steps.

Choose one to seven events
Map your physical keys to the moments you need to observe: a dispenser, a lever, a choice, a response.
Record the duration
Hold a configured key while the event occurs. Live values make the observation easy to follow.
Take the CSV with you
Export interval-based durations that open cleanly in a spreadsheet, R, Python or your existing lab workflow.

The data stays legible.

A good observation ends with a file you can understand. Every row is an interval. Every value is a duration in seconds. Nothing is hidden behind a proprietary dashboard.

From keyboard signal to usable CSV.
