Indoor Humidity Tracker
Log and chart humidity readings over time
Tracking humidity over time is far more useful than a single reading. Log your temperature and humidity, watch the trend on the chart, and export your data to CSV. Everything stays in your browser — nothing is uploaded.

How to read the results
Look for patterns: humidity that climbs overnight, spikes after bathing or cooking, or stays high in one room. A reading drifting above roughly 60% for sustained periods points towards ventilation and moisture-source improvements.
