Barometer.today
Barometer.today shows barometric pressure worldwide
UV has an index. Air quality has AQI. Pollen has counts. Someone is mandated to publish each of those, so the pages exist and they are decent. I have built sites on exactly that assumption before: uvi.today, airindex.today, pollen.today. In each case the data was already public and my job was presentation.
Air pressure has nothing. No agency owes you a barometric index, so the demand just sat there for years, landing on forecast pages that answer a different question.
That gap is barometer.today. It says in one sentence what pressure is doing where you are: rising or falling, how fast, when it turns. That is all. No dashboard, no advice, no interpretation of your headache.
Live now in nine languages, about 5,800 city pages, no ads and no cookies, running on my own hardware for about EUR 15 a month alongside the others.
Would like feedback on whether the front page reads clearly to someone who has never thought about pressure before.
About
Lots of people feel air pressure changes, but weather sites show pressure as one number in a table. I wanted a site that just says whether it is rising or falling, how fast, and when it turns.
