4/5Pro Altimeter Update
This version of the App has effectively resolved an issue related to display on IPhone6. The app is easy to calibrate and read due to the larger text. Well worth the 0.99 cents.

5/5This is what I was looking for!
While trying to determine elevations for setting multiple very sensitive digital barometers at different levels indoors, I used a combination of USGS topo maps, a couple of pressure equations, and moving up and down hill with a barometer to record pressure changes to predict estimated altitudes where the stationary barometers are. Pretty much had to work it out inside-out and in reverse. Then I happened to see this altitude app available in the Theodolite app (never came across it when searching the App Store, though), and it’s exactly what I was needing. I took it to an open spot outside where an online high-res USGS topo map showed 1,261 feet elevation, entered that as the calibration, then quickly took my phone to the barometer locations. Based on the app elevation readings, the difference between the predicted pressure and the values calculated using this app’s numbers showed that the prediction was only 0.08 millibars off, or within about 5 feet elevation. It was kinda cool to see how closely the reverse-engineering turned out to be, but I’d much rather have skipped all that nonsense and found this app a lot sooner.

5/5Barometric???
Right now I fail to see how this is anything more than all the other GPS location barometer apps in the App Store. You can enter your local pressure, but it still only gives you GPS altitude on both my iPhone and Apple watch. Another barometer app I use reflects the actual local station pressure, so I am quite sure that the sensor in my iPhone is working properly. Review Update: I downloaded Pro Altimeter to both my iPhone 14 Pro and to my Apple Series 8 watch at about the same time that Apple updated their software which messed things up. I am changing my star rating due to the quick response from the developer, which can be read below.

3/5Great calibration. How about some functionality?
Love the multiple methods of calibration and the accuracy it provides… but now this app needs some features to make it useful. Altimeter: Climb and descent rate measured over time or between pre-determined altitudes for us climbers and skiers. The ability to display change in altitude over time in both data table (exportable to spreadsheet) and graph/graphic form. Altitude alarms to signal when a particular altitude has been reached. Barometer: pressure change over time is a good indicator of weather trends. How about recording pressure at user selectable time intervals in the background and then displaying collected data in table form (exportable to spreadsheet) and graph/graphics forms? Maybe display airport data on a map so user can see surrounding pressure readings and get a picture of pressure trends in area? App is a good start from an accuracy, calibration point of view. Now add some useful functionality.

5/5Correction for iOS 17.4
This is a great app. I use it for taking small measurements in height used in drainage systems where accurate GPS is spotty. Thank you so much for readdressing the barometer sensor.

1.0
1.0.1
This update from Apple will improve the functionality of this app. No new features are included. Fix to interface layout for devices running system wide display zoom. If you're happy with Pro Altimeter, please leave us a review on iTunes. It only takes a minute, and helps a lot. Reviews establish the app and improve sales, in turn providing support for future development. Thanks!
1.1
Tweaks for iOS 16 and new devices.
1.1.1
Update to handle unannounced changes in the NWS AviationWeather API that supplies airport weather data for calibration.
1.1.2
This version contains a workaround for privacy/permissions issues on iOS 17.4.x that block access to the barometric pressure sensor. You will be required to grant permission for access to Motion & Fitness activity. On devices that do not support Motion & Fitness, or in cases where the user declines permission to access Motion & Fitness activity, only GPS altitude will be shown in the app. Please contact [email protected] if you have any questions or concerns.
1.1.3 · 28 Sep 2025
Update to deal with changes in the NWS aviation weather data server used to calibrate with airport METARs.
