Lieber Entwickler : Wieder aus dem Urlaub zurück ? ### 4/5 — Fits my purpose. *2018-11-28* 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. ### 4/5 — Almost Perfect! *2018-07-14* Would love to be able to use in landscape mode but otherwise it's great! ### 5/5 — Worked when I was without data crossing the Pacific *2017-05-06* Great app! ### 5/5 — Almost perfect *2016-12-18* 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. ### 1/5 — Inutile *2015-11-21* Inutile (ne fait rien, même pas de la conversion) et trop cher pour ce que c'est: devrait être gratuit. ### 1/5 — Pro Security Consultant *2015-10-20* Clicked on the icon and it went dark and said "waiting".....its been 12 hours and I'm still waiting. I really enjoyed it when it worked ### 1/5 — no good for iPad 2 *2015-09-17* got this as part of bundle but is no use unless you have iPhone 6 ### 5/5 — Please add pressure and altitude history graph *2015-04-14* Fantastic app, please add pressure and altitude history graph. Thank you. ### 5/5 — Simple and Brilliant!!! *2015-01-31, version 1.0.1* I appreciate an app that is simple and works well. Absolutely worth every penny! Only two things I would add: Latitude and Longitude Bearings and barometric pressure change over time. Still deserves five stars! ## Most critical reviews (10 lowest-rated) ### 1/5 — App crashes instantly on iPhone 17 (iOS 26.5.2) *2026-07-11* Just purchased this app and it opens for 1/10th of second then crashes and disappears. Dev - Please update this app asap (or remove it from the App Store and refund me) ### 1/5 — Did not work *2026-04-17* Paid, loaded,did not work, just wanted a simple manual input conversion tool ### 1/5 — No longer works or supported *2026-04-12* I downloaded this app years ago and it worked great for about 3-4 years. Amazingly accurate. Now it opens for just a few seconds then crashes. Unusable. Disappointing for an app I paid $20 for. ### 1/5 — Crashing *2026-01-24* Crashes in under a second. ### 1/5 — Http error 410 *2025-09-28* Purchased version for iPhone 16pro max. Calibration with Check nearby airport gives error message: http error 410- means resource permanently removed. Why ? Make it available. ### 1/5 — Crashes right away *2025-03-17* Unfortunately, the app crashes as soon as you open it. ### 1/5 — App crashes *2025-01-01* Bought this with the bundle after four or so years of Theodolite. That app is perfect. This app never loads once after purchase. Would like to understand why. ### 1/5 — Terrible *2024-10-12* Shuts down as soon as you try to open it. Total fail. Do not buy. I want my money back! ### 1/5 — Barometric??? *2024-03-16* 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. **Developer response:** Apple introduced a major bug in iOS 17.4 which prevents the barometric pressure sensor from getting privacy permission to deliver data to apps. I filed a bug report in early March and am told they are working on a fix, but no timeline was given. Until they fix the problem, the only solution is to downgrade to iOS 17.3.x, which is not practical for most people. So we have no choice but to wait. Once Apple releases their fix, I will most likely need to update the app to make it reset privacy permissions so it can start getting pressure data under 17.4.x. ### 1/5 — Baro not accurate *2017-09-17* When calibrated with local altimeter setting, altitude off by 100 feet ## Most praised reviews (10 highest-rated) ### 5/5 — Simple et efficace *2026-03-02* Application parfaite pour qui sait l’utiliser. ### 5/5 — App crashes when iOS permissions aren’t addressed, app is excellent. *2025-01-04* Bought this with the bundle after four or so years of Theodolite. That app is perfect.-edited- App works well! After making “Health and Fitness” changes to iOS settings, app functions perfectly!! Thanks for the response and feedback! **Developer response:** As of iOS 17.4, Apple requires Motion & Fitness permission for altimeter apps to use the barometric pressure sensor. If you have disabled Motion & Fitness on your device or have not given the app permission to use Motion & Fitness, then it will not be able to function. Once the app is able to use Motion & Fitness, it should run fine. ### 5/5 — Fantastic app and design *2024-04-01* This app is a joy to use. It has a super clear no-nonsense interface. If you are not familiar with altitude measurement by barometer, the text in the app description has a very clear and well written explanation. I compared some altitude apps, this is by far the best in form and function. ### 5/5 — Barometer working again *2024-03-25* The barometer has started working again. It wasn’t the developers fault, it was a bug apple brought in. Recommended. ### 5/5 — Correction for iOS 17.4 *2024-03-25* 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. ### 5/5 — Barometric??? *2024-03-19* 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. **Developer response:** Apple introduced a major bug in iOS 17.4 which prevents the barometric pressure sensor from getting privacy permission to deliver data to apps. I filed a bug report in early March and am told they are working on a fix, but no timeline was given.

Perfect! ### 5/5 — This is what I was looking for! *2021-10-30* 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. ### 5/5 — Perfect *2019-12-27* Great app! Perfect - only what is needed. Can’t wait for the Apple Watch version! ### 5/5 — Best altimeter in the App Store *2018-08-25* Reliable, simple, clean. --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/).
