Pro Altimeter - Barometric+GPS

When i first saw the icon for this app i thought it was going to be a bit cheap and nasty, infact thats probably the only suggested improvement i could suggest. This app keeps it simple and is exactly what I wanted, the ability to key in the current barometric pressure based on my location and get a half decent altitude reading. Its clean, simple doesn't crowd things out with a whole heap of settings. Everything you need and nothing you don't.

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.

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.

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.

Please bring this to Apple Watch. I work in Military aviation and this would help so much on Apple Watch. And add landscape view option.

Reliable, simple, clean.

Would love to be able to use in landscape mode but otherwise it's great!

When calibrated with local altimeter setting, altitude off by 100 feet

Great app!

Great app!!! If you just added a couple other instruments it would be perfect! But I'm giving it 5 stars anyway because of the calibrate feature. Where it goes out and gets baro from metars automatically when selected.
