No longer works or supported

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.

FAQ

What does Pro Altimeter do?

Pro Altimeter measures and computes your altitude using your iOS device's built-in barometric pressure sensor and GPS. It provides real-time altitude readings with accuracy estimates and offers various calibration methods to ensure precise measurements.

How do I calibrate Pro Altimeter?

You can calibrate Pro Altimeter using four methods: GPS altitude, manually entering your current altitude, manually entering local barometric pressure (e.g., from a weather report), or by checking nearby airport METAR data. The app will also remind you to recalibrate periodically.

Is Pro Altimeter free to use?

Yes, Pro Altimeter is a free application. It does not have in-app purchases or advertisements, offering its full functionality without any cost to the user.

What devices is Pro Altimeter compatible with?

Pro Altimeter is intended for iOS devices with a barometric pressure sensor, including iPhone 6 and later, iPad Air 2 and later, iPad mini 4 and later, and iPad Pro. On older devices without a barometric sensor, it will only display GPS altitude and accuracy.

What are the main use cases for Pro Altimeter?

This app is useful for hikers to track their elevation gain and loss, for pilots to cross-reference altimeter readings, and for general outdoor enthusiasts who want to know their precise altitude in various environments.
