the moon is pulling the atmosphere above you right now. the pressure change is tiny — about 1-2 hectopascals peak to peak. your phone can measure it. this tool needs days of logging to show you. check back.
most mid-to-high end android phones and iphones from iphone 6 onwards have a barometric pressure sensor. budget phones often do not. data is stored locally in your browser via indexeddb — nothing leaves the device.
