Alti-Barometer Pro is in a class by itself.

Why?

Because "barometer" apps that make you manually take new readings can't give you the most important function of a real barometer: automatically and accurately tracking pressure and trends at precise time intervals. And basic altitude apps that convert raw air pressure data to altitude data without accounting for weather-related pressure changes can be off by hundreds of feet as the weather changes.

Alti-Barometer Pro rewrites the rules for mobile barometers and altimeters with two unique capabilities:

- Instead of making you do all the work, Alti-Barometer Pro automatically and continuously logs and analyses pressure data in the background using your device's pressure sensor with no intervention required.
- Using proprietary algorithms developed over years of research, Alti-Barometer Pro automatically compensates barometer readings for changes in altitude, and automatically compensates the altimeter for changes in weather-related air pressure.

In combination, these two innovations reset expectations for mobile barometer and altimeter performance and capability.

Make no mistake. Alti-Barometer Pro is a real barometer that can keep pace with professional-grade weather stations, and is also a very accurate altitude tracker. The app runs in the background and keeps track of air pressure changes in 15-second increments - a rate exceeding most dedicated weather instruments.

One of Alti-Barometer’s breakthrough innovations is BaroTrak, a feature that continuously compensates for changes in altitude without using power-hungry GPS or Internet access - a first for any mobile altimeter/barometer. Say goodbye to altimeter “drift” due to weather-related changes, and spikes in barometric pressure readings and false alerts time your altitude changes. BaroTrak’s innovative algorithms reset the bar for mobile barometer/altimeter performance.

Because of its unique ability to continuously collect and analyze pressure data while keeping power consumption to a minimum, Alti-Barometer Pro shows you altitude and barometric trends and data for up to the past 48 hours using beautiful, fully-interactive graphics on your iPhone or Watch. And with the optional subscription upgrade, you can automatically save and view daily snapshots of your altimeter and barometer logs.

Alti-Barometer’s innovative solutions turns any iPhone into a barometric weather station. With it’s unique BaroMap feature, Alti-Barometer Pro shows you barometric pressure information across the app's user community on a fully interactive map.

And Alti-Barometer Pro’s "Share" feature allows you to easily share interesting barometer or altimeter graphs through social media, messages, or email.

Alti-Barometer Pro supports all Watch complication styles and iOS widgets to keep you up to date with altitude and barometric pressure trends at a glance. The app's Watch complications and widgets are fully live, which means that you see current data and trends without having to manually refresh the data - another unique capability that sets Alti-Barometer Pro apart from the others.

Alti-Barometer Pro includes a Storm Alarm feature to notify you of large changes in barometric pressure. And outdoor enthusiasts will appreciate the app’s climb and descent logs as well as real-time vertical speed and altitude trend reporting.

As an upgrade feature, the app also provides full CSV-compatible data export and import so you can save a record of a hike, climb, or that big storm and analyze or view it later.

We originally developed Alti-Barometer Pro because we missed the altitude/barometer functionality of our dedicated ABC (altimeter/barometer/compass) watches. We couldn’t find an app that even came close, and we decided to create something much better.

Enjoy!
