Current pressure and trends
See the current reading, 3/12/24/72-hour ranges, and sample source; unsampled intervals stay visible as gaps.
One quick log
Record a headache, joint discomfort, sleep note, or custom observation with a 0–10 intensity and local pressure snapshot.
Pressure–Feeling Atlas
Review your own entries, sample counts, and pressure changes by time range without turning an observation into a diagnosis or causal claim.
Calibration and hikes
Use known altitude, station QNH, or manual QNH, then track relative ascent, descent, peak, and duration in a local hike log.
Local CSV / PDF
Export samples, entries, and the relationship report by range, with source, sample-count, and demo-data provenance.
Widget and Watch
Check the latest local sample from the lock screen, Widget, or Watch with direction and update time.
Who it is for
From one glance to your own timeline
Want to see pressure change?
Open the app for a current reading and trend from local samples—no account or cloud history required.
Want to log a personal observation?
Save what you noticed, then keep the time window and sample count visible in the neutral report.
Need altitude context before a climb?
Choose a calibration method, confirm the result, and start a relative hike log from an explicit zero point.
Offline or no barometer?
The app explains the limitation; logging, reports, and local export remain useful, and demo data is clearly marked.
Common questions
Data, privacy, and limits
Does BaroLog diagnose headaches?
No. It organizes your own observations beside local pressure samples; it does not diagnose, treat, predict, or claim causation.
Is location or WeatherKit required?
No. Optional station context can be skipped; local pressure and logging remain available when location or network is unavailable.
Does data leave the app?
The current version has no developer server, account, advertising, tracking, or cloud history. Exports leave the app only when you choose the system share sheet.
Is demo data real health history?
No. Store and test examples use synthetic or sanitized records and are labeled as demonstration data in the app.
