Alti-Barometer Pro uses your iPhone’s or Watch’s sensor to automatically and continuously record your barometric pressure and altitude. Even while your iPhone is in standby or you're using other apps, Alti-Barometer will seamlessly process and record pressure data in the background. Using beautiful interactive graphs, our app shows you barometric pressure trends over hours and days to help you understand which way the weather may be headed. Our app supports a broad range ofl auto-updating widgets and Watch face complications. It also supports Apple’s Live Activities to let you see real-time pressure, altitude, and compass direction. And to make sure you don’t get caught off guard, the app’s Baro Alert capability automatically notifies you of large changes in barometric pressure. The Apple Watch is always a top priority for us, and the powerful Watch app can run completely independently from your iPhone and transforms your Watch into a true ABC (altimeter/barometer/compass) watch. And our Watch app includes a rich set of complications you can choose from to make your Watch face come alive.. Our BaroMap feature lets you see what’s happening around you by displaying pressure trends across the app’s global user community on an interactive map. And whenever you need a world-class high-precision altimeter, Alti-Barometer is ready. A true pressure-based altimeter, our app can keep track of even the smallest altitude changes with far greater precision than battery-draining GPS apps. In addition to altitude, Alti-Barometer displays vertical speed and keeps track of key stats such as total ascent and descent times and distances. And because it’s handy to know what direction you’re heading, Alti-Barometer displays a handy compass on the altimeter screens. The History feature automatically saves daily snapshots of your pressure and altitude data using Apple’s secure iCloud and lets you interactively explore historical data across weeks, months, or years. Want to see the pressure graph of that big storm last year? With our history capabilities, you can. We also made it easy to share a snapshots of baro or alto graphs through social media, email, or messaging with our one-tap share feature. Our exclusive real-time wind analyzer estimate local wind speed using only your device’s sensors - not internet required. Now you can know how hard the wind is blowing even in the middle of nowhere! Alti-Barometer also shows you weather conditions and forecasts using data from the global network of NOAA/ICAO weather stations - the same weather information that pilots use around the world to fly safely. It’s real weather from real weather stations. And our app has a full suite of weather condition and forecast notifications so you’re never surprised. And even the free version of our app is 100% ad-free to provide the best possible experience. If you need even more capabilities, the Premium Features upgrade unlocks iPhone widget support, CSV file data import and export, unlimited history, additional Watch functionality, extended recording time, extended altimeter run time, and much more. Although some features require internet connectivity, rest assured that Alti-Barometer can operate completely offline indefinitely and was designed to be a true wilderness and off-grid companion. So why all the features and capabilities that nobody else has? Because we’re weather nerds and outdoors enthusiasts, and we couldn’t find a real altimeter/barometer app that came anywhere close to our expectations. So we set out to build what we believe is now the world’s most advanced barometer/altimeter app on any platform, period. If you want the best, give our app a try. We hope you enjoy it as much as we do! Privacy policy: https://www.bogbridges.com/altibarometerproprivacy Terms of use: https://www.apple.com/legal/internet-services/itunes/dev/stdeula/
