The current app, configured for a two-event observation.For researchers who need a reliable signal, not another complicated system.
↓WHY KEY RECORDER
Small surface. Serious signal.
02
Record the duration
Hold a configured key while the event occurs. Live values make the observation easy to follow.
03
Take the CSV with you
Export interval-based durations that open cleanly in a spreadsheet, R, Python or your existing lab workflow.
USE CASES
Built for the moments you need to measure.
01
A clear tool for controlled behavioral observation.
Mark when two events happen, keep the measurement local, and leave the interpretation in your own research workflow.
Read the use case ↗02From keyboard signal to usable CSV.
Key Recorder produces a small, legible file that can move directly into a spreadsheet, R, Python or a lab archive.
Read the use case ↗A REAL PROTOCOL
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.
