Professional barometer. You will be able to view the trend of atmospheric pressure in real time, thus forecasting the change in weather. Absolute precision through the parallel operation of different sensors, such as device pressure sensor, GPS sensor, and remote connection to weather stations near you. Re-propose a barometer with an analogue dial, available both with international measurement (hPa) and with Anglo-Saxon measurement (inHg), you can view the weather forecast, the temperature and the percentage of humidity in the air. Very interesting is also the possibility to take a photo with the superimposed weather data and some effects that can be activated in certain weather conditions and share them with the most famous social networks: facebook, whatsapp, instagram, email etc.

Free barometer & altimeter — real-time pressure, altitude, 10-day forecasts with migraine alerts, automatic history logging, and CSV export all in one app. The dashboard displays high-precision real-time measurement data, offering peace of mind for mountaineering enthusiasts and outdoor adventurers. It uses your device's built-in barometric pressure sensor, motion sensor, and GPS, allowing offline use. It also features real-time trend graphs, making it ideal for observing short-term changes during typhoon approaches, sudden downpours, stair/elevator ascents/descents, or driving uphill. The altimeter lets you simultaneously view readings from three sources—sensor, GPS, and QNH (sea-level corrected pressure)—plus a calibrated value matched to a known elevation such as a trailhead. Each altitude is displayed visually on an arch gauge, and you can tap each source to learn about its characteristics and accuracy. Since barometric pressure and altitude support various units, it can also be used for professional purposes by researchers and academic institutions. Additionally, for those sensitive to weather changes and suffering from migraines or weather-related illnesses, it provides graphs forecasting barometric pressure and weather for the next 10 days, along with medically grounded headache alert information updated every 6 hours. Its graphical, intuitive UI runs smoothly, making it a valuable tool for daily prevention and countermeasures. Furthermore, measured barometric pressure data is automatically stored within the app. It features a background measurement mode that enables measurements even when the app is in the background or asleep. You can view accumulated data and export it to CSV files. It also supports Live Activities in the background, allowing you to view real-time data on Dynamic Island or the lock screen. Beyond the main app, it also works with Apple Watch, letting you instantly check barometric pressure and altitude. An all-in-one, high-performance barometer app covering all present, future, and past information related to barometric pressure. The one-of-a-kind app you never knew you needed—that's "Torr"!! 【Features】 ・Dashboard  ・Barometer (Atmospheric pressure data via pressure sensor)  ・Altimeter — View altitudes from 4 sources on arch gauges   ・Sensor Altitude (absolute altitude from the barometric sensor)   ・GPS Altitude (elevation above sea level via satellite positioning)   ・QNH Altitude (sea-level corrected barometric altitude)   ・Calibrated Altitude (calibration matched to a known elevation) ・Pressure Forecast  ・Up to 10 days of nearby sea-level pressure values and weather forecasts  ・Pressure graph showing trends like rises and falls  ・6-hourly migraine/weather sensitivity alerts based on medical evidence ・History  ・Automatic data logging  ・Daily history export to CSV files  ・Background measurement mode ・Unit settings — 7 pressure units including Torr, hPa, kPa, mBar, psi, inHg, mmHg ・Color theme settings ・Torr Pro plan for ad-free experience ・Apple Watch compatibility ・Lock screen widget ・Live Activity 【Other】 Some devices may not have a barometric pressure sensor or motion sensor. Please note that in such cases, certain dashboard features may not be available. Location access and an internet connection are required to use the barometric pressure forecast. Location access is required for background measurement. Please submit requests or inquiries via reviews or the support URL.
