baro watches barometric pressure where you are and warns you about a drop that can turn into a migraine day — so you can plan your day around it.

a 48-hour pressure line with the rough stretches shaded — down to the hour, not just the vibe.
baro warns you hours before a rough window opens. alerts are scheduled on your phone, so they fire even offline.
tap how bad it is, done. optional cycle tracking, optional notes. no forms, no guilt if you miss a day.
the more you log, the better baro reads you — your thresholds, your worst hours, how your cycle stacks with the pressure.
migraines are hard — and we still understand them far too little. baro can't fix that overnight. but every rough day you see coming, and plan around, is a day the migraine doesn't win. that's baro's mission.



every day gets a colour, a shape and a word — it reads at a glance, and it still reads if you're colourblind.

steady pressure. live your life.

pressure's going up — mind how you feel if rises tend to get you.

a lil dip coming — nothing wild, just a heads-up.

a real dip — be soft with yourself, take it slow.

sharp drop incoming — take a break if you can.

big pressure drop — rest up and go easy on yourself. 🩵
rising is the odd one out — it's not a step on the drop ladder, it's pressure going the other way. some people feel rises too, so baro tracks them on their own axis.
the six levels aren't universal — baro calibrates its thresholds to a year of your area's own weather, so a "rough" day is rough for where you actually live.
as you log, baro works out which drop window hits you — the fast 3-hour dips or the slow 24-hour slides — your odds on drop days, and how your cycle stacks with the pressure.
insights come with real statistics — and they'll happily say "too early to tell" until your log has enough days to mean something.
“heads up — a big pressure drop starts around 9pm. maybe get ahead of it.”
“thanks for telling me. that's twelve days of pattern i can actually use.”
“clear skies for three days. nothing to brace for — go enjoy it.”
your headaches, cycles and notes live on your phone — backed up only to your private icloud, which nobody but you can read. not even us.
no email, no sign-up, no password to forget. open it and it works.
baro's server does one job: it turns coordinates into weather and risk. it never sees your name and never stores your logs.
no analytics, no ads, no third parties watching your health. the app never phones anyone but its own weather server.
