Baro
migraine diary that never sees your data
Baro is a 100% on-device migraine diary. Log an attack in one tap, and let on-device statistics surface your real triggers — short sleep, falling pressure, humidity — each shown with its evidence. No account, no SDKs. The App Store privacy label reads "Data Not Collected."

Hey Product Hunt 👋 I built Baro after years of being told my migraines were "probably the weather" — with no real way to prove it. Baro is a migraine diary with one hard rule: your data never leaves your phone. No account, no analytics, no third-party SDKs. The App Store privacy label reads Data Not Collected on every row — and because there are zero SDKs, that's verifiable, not just a promise. How it works: • Log an attack in one tap when it hits — even mid-migraine, in a dark, low-glare mode. • Baro freezes the context — sleep, heart rate, barometric pressure, humidity — from Apple Health & Apple Weather, all on-device. • On-device statistics (not a black-box model) surface your real patterns: "3× more likely after nights under 6h — 14 of 22 attacks." Every insight shows its evidence. • A daily forecast flags when today's conditions line up with your past attacks — before one starts. • One tap creates a clean PDF for your neurologist. Logging is free forever. Pro adds the patterns, forecast and doctor report (14-day trial, or a one-time Lifetime for the subscription-averse). iPhone + Apple Watch + widgets + Lock Screen, in 10 languages. Baro is a self-tracking tool, not a medical device — insights are associations, never a diagnosis. I'd love your feedback, especially on the privacy model and whether the insights feel trustworthy. AMA! 🙏
