FREE VS PREMIUM Pressure reading, trends, and calibration are always free. Lock Screen widgets and the in-app barogram include a 7-day free trial. After the trial, unlock them forever with a one-time purchase. No subscription. REQUIREMENTS Requires an iPhone with a built-in barometric sensor. PRIVACY Pressure data is stored only on your device. No account required. Note: BaroWidget shows barometric pressure for informational purposes. It is not a weather forecast or medical device.
