Review momentum (0-100) blends how fast the app collects ratings compared with other apps in its category (60%), whether that pace is speeding up (25%) and what recent raters give it (15%; recent stars well below lifetime pull it down). Ratings counts are read daily. A jump usually means a launch, a feature, ads or a new review prompt.
About Torr: Barometer Altimeter
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 headache alert information based on published research, 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"!!
