Barometric Pressure Offline

The app reads the device’s built‑in pressure and altitude sensors to calculate sea‑level pressure and altitude directly on the phone, storing all data locally. It presents a live reading, a 7‑day graph, and a history view with notes, while allowing export of the recorded values in CSV or JSON formats. Users can add widgets to the lock or home screen for quick access and set alerts that trigger when pressure changes rapidly.

It is aimed at people who need offline atmospheric information, such as outdoor enthusiasts, sailors, hikers, and individuals monitoring health conditions that may be influenced by barometric shifts, including migraines, asthma, or arthritis. The software does not require an internet connection, accounts, or external servers; all processing and storage occur on the device.

Distinctive aspects include offline operation, configurable pressure‑change alerts, and the ability to annotate and export data without relying on cloud services. The focus is on a minimal, sensor‑driven experience that provides actionable pressure trends and altitude information for personal weather awareness and body‑symptom tracking.
