Heavy head on a low-pressure day. But was it really the weather, or the short night and the third coffee? You cannot tell until you record it and look back.
Feel Log logs pressure drops, rain, sleep hours and steps automatically from Weather and Health, and lets you check off coffee, meals, supplements and habits in about 30 seconds a day. After a few weeks, you can see what your harder days tended to have in common, across every factor at once.
This app does not diagnose, treat, prevent, or show medical effects. It records subjective impressions only.

Ratings & Reviews
- This app hasn’t received enough ratings or reviews to display an overview.
Reports are easier to read at a glance. Factor-on vs. factor-off days now show as bars, factors common on harder days get ratio bars, and the calendar is filled with your feel colors with marks for pressure drops, rain and short sleep. The weekly tab opens with a 7-day chart, and Home shows on / off / delta as three numbers.
