About

Read full description

BaroNote is a simple barometer and personal log. Check the current air pressure, see whether it is rising, steady, or falling, and save a quick private note about your mood and condition. In History, BaroNote places the available six-hour pressure movement beside your log without judging the cause or making a forecast. Features: - Current air pressure from the iPhone pressure sensor when available - Rising, steady, and falling trend display - Mood, condition, symptom tags, and optional notes - History with the available six-hour pressure movement - Optional Health link for matching condition and mood records - hPa, mb, inHg, and mmHg units - Home Screen and Lock Screen widgets - No account, tracking, ads, or server upload Health linking is optional and off by default. BaroNote writes headache and fatigue, plus mood on iOS 18 or later. It does not read Health data. Sleepiness, low focus, stiff shoulders, pressure, and notes are not written to Health. Your BaroNote records stay on this device. BaroNote is for personal logging only and does not provide medical advice, diagnosis, treatment, or forecasts.

Verdict

The call

The clearest difference is in-app purchases: BaroNote at none against DustMap's 4. BaroNote also leads on ads (none vs shown) and update cadence (every 2 days vs every 5 months). DustMap's advantage is device support (3 vs 1) and iOS requirement (15 vs 17.0). On price there is nothing between them.
