Feature Highlights Dual‑display Barometer & Altimeter All‑in‑One ‑ Shows real‑time barometric pressure and altitude simultaneously, no need to switch between multiple apps. ‑ Dual pressure readout: raw sensor value from Apple Watch and ISA standard pressure calculated by altitude. Ripple background animation visualizes pressure level intuitively. ‑ Displays weather symbol alerts when rapid short‑term barometric changes suggest possible weather shifts (for reference only). ‑ Merges Watch‑built‑in altitude and GPS altitude. Fine pressure variations dynamically calibrate altitude for higher precision. ‑ Records pressure & altitude changes, visualized with numbers and scales. Long‑tap the change value to reset. ‑ Auto‑calibration triggers when deviation against system altitude becomes large, balancing overall accuracy and sensitivity to subtle variations. ‑ Tap pressure value to toggle units: hPa, inHg, mmHg. Altitude supports meters / feet. Rich Watch Face Complications ‑ Circular complications for pressure and altitude for quick glance. ‑ Stack‑able rectangular complication tracks 24‑hour pressure‑altitude trends with current readings. Keep it on watch face to enable continuous logging.
