Thermal comfort is that particular state of mind that expresses satisfaction with the surrounding environment. With Thermo Hygrometer we offer you the best tool with an optimal algorithm specialy created for the index THI (Thermohygrometric Index) that allows you to have an eye on these two factors, humidity and temperature, for a better life. Thermo Hygrometer gives you the outside temperature and humidity values ​​in real-time with forecast for the next 10 days. See also the hourly chart of temperature and humidity for 10 days. Its unique design has been created to offer maximum visual index THI simplicity. [ Features ] • Real-time Hygrothermal Index and forecasts for the next 10 days • Hourly outside temperature and humidity and chart for 10 days • The best algorithm specialy created for the index THI • Weather conditions • Outside temperature indicator • External moisture indicator • Indicator latest data update • Temperature expressend in Celsius, Fahrenheit and Kelvin • Your GPS location is used to calculate the index THI • Save favorite locations (unlimited) • Intuitive Graphics • Ease to use [ Thermohygrometric Index Meaning] The Thermohygrometric Index (THI) is an index that aims to roughly calculate the Thom Index (heat discomfort) directly with temperature and relative humidity, thus excluding from the calculation the temperature the wet bulb. The THI, unlike the index of Thom, is an index which goes directly to a climate classification, rather than to a biometeoclimatica classification system, starting from specific hygrothermal values. It is valid both for extremely hot weather phases, as for very cold periods. With temperatures above 46°C, even with changes in relative humidity, the index always identifies the extreme class. The following table shows the temperature threshold with its bio-climatic categories or, rather, climatic. In this index (as for other indices taken into account) is not taken into account wind factor. [ Compatibility ] • Devices: all iPhone, iPad and iPod. • iOS: 9.3 or later.

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.

Verdict

The call

The clearest difference is update cadence: Barometer on‑Wrist at every 2 weeks against Thermo Hygrometer's every 7 months. Barometer on‑Wrist also leads on price ($0.99 vs $1.99). Thermo Hygrometer's advantage is iOS requirement (9.3 vs 26.0). On ads, in-app purchases and device support there is nothing between them.
