One tap logs it on the pressure curve. Stays on this device — not medical advice.
After a few logs, MyGlass will tell you whether they sit on falling pressure.
MyGlass reads the built-in barometer when the browser offers a pressure sensor. Otherwise GPS plus nearby weather still give station pressure, altitude, history, and forecast — and the last readings keep working offline.
