Barometer Plus app measures air pressure and altitude using your device's built-in barometric pressure sensor. Because air pressure changes usually indicate a weather change, you can use this app to monitor and predict short-term weather variations. People suffering from migraine, headaches, or joint pain can monitor how barometric pressure impacts their mood. Fishermen can monitor the atmospheric pressure for right-time fishing. FEATURES: • The app contains a barometer and altimeter with a personalization graphic in classic analog style. It also displays the current temperature and humidity. • Display barometric pressure (sensor value) or mean sea level pressure (MSLP - value used in weather forecast services or stations). • Units support for pressure: mb, inHg, kPa, atm, Torr, psi, hPa, mmHg. Units for altitude: meter, feet. • Calibrate the barometer using altitude/location from the GPS. Calibrate the altimeter using the nearest airport information/METAR, or manually enter the QNH of the nearest airport. Offset sensor output value. • Measure the height (building/mountain/hiked/climbed) using the "Relative Altitude" feature (can be enabled in the app's Settings). • Notification about pressure change. "Notification custom rule" for you to define how and when the app sends notifications. Notify when air pressure changes indicate that extreme or worse weather may occur. • "Pressure Tracking" and "History Graph" require "Background App Refresh" or "Always Location Service" with "Exact update interval" (paid feature) enabled. • "My Area" allows you to define your frequent stay places, and the app tracks air pressure with location data. • Export history to CSV format and Today widget (paid features). • This app is the digital version compared with an aneroid or mercury barometer and can be adjusted to MSLP with additional features. CUSTOMIZABLE: You can change your barometer/altimeter appearance with: • Seven different housing colors. • Black, white or blue disk background. • Four different app backgrounds. • Three different types of needles. • Marker needle for easily monitor. • Dark or light Today widget theme. NOTES: • App only works on devices with a barometer sensor, such as iPhone 6/6s/7/8/X/11/12/13 (including Plus models), iPad Mini 4/Air 2/Pro, or later. • Weather icons on the dial: This only shows the air pressure trend like in an analog barometer. • Each time your device reboots, open the app for tracking with the "Exact update interval" feature work. • You may take the phone/tablet far away from computers, cables, and other magnetic sources to get accurate results.

About

Weather Alert

Features
Read full description

Weather Alert is a focused fire-weather monitoring app built for the Joe Rich area of the Central Okanagan, BC — designed to give residents, firefighters, and anyone who cares about wildfire risk a clear, real-time picture of the conditions that matter most. FIRE WEATHER ALERTS Get notified the moment conditions turn dangerous. Alerts are organized into three risk levels that escalate with the actual danger: • Low — high temperature alone • Medium — high temperature combined with low humidity (Hot & Dry Conditions) • High — high temperature, low humidity, and strong wind together (Fire Weather Warning) Only the single most severe match ever notifies you, so you're never bombarded with redundant alerts. TWO WEATHER STATIONS, YOUR CHOICE Choose which live station drives your alerts — the primary local sensor, or a neighboring station with its own wind sensor. View one at a time with a swipe, or both side-by-side at once. LIGHTNING ALERTS Get pushed a notification the moment a lightning strike is detected within a radius you choose (5, 10, 20, or 30 km) of the station, powered by the community Blitzortung.org lightning network. Runs entirely server-side, so alerts still arrive even when the app is closed or your phone is asleep. LIVE WIND MAP See current wind speed and direction at a glance, plus the regional wind pattern across the surrounding area — helpful context for understanding how fire risk might spread. 5-DAY FORECAST Current conditions and forecast, including UV index and air quality (PM2.5), so you have the full picture in one place. BACKGROUND ALERTS Every alert — fire weather or lightning — can reach you even when the app is closed, thanks to background push notifications. YOUR PRIVACY Weather Alert collects nothing. No accounts, no analytics, no tracking, no third-party SDKs. All your settings stay stored locally on your device, and notifications are delivered only through Apple's own push service. Nothing about you is ever collected or shared.

Verdict

The call

The clearest difference is in-app purchases: Weather Alert at none against Barometer Plus's 4. Weather Alert also leads on ads (none vs shown) and update cadence (every 9 days vs every 6 weeks). Barometer Plus's advantage is iOS requirement (13.0 vs 17.0). On price and device support there is nothing between them.
