Don’t transcribe ATC well at all

I paid for transcriptions several times. Transcriptions were terrible. Found Google Live Transcribe did a much better job and a lot more ACCURATE. Tried contacting Stratus Horizon several times to talk with someone about it. They didn’t really seem to care! Do, I use Google Live Transcribe! I am an 8250 hour pilot and Flight Instructor!

By the way, look at the ages of the reviews!

Great App

I’ve had my stratus 2s for over 5 years now with no issues, one day however the ADS-B function stopped working. Downloaded this app and installed the firmware and it’s good as new. Only issue I see with the app is if you turn might mode on it disrupts the firmware download screen.

Works on iPad but not my iPhone

I have an iPhone ES and an iPad. The transcription on my iPad works ok with some misses or long transmissions cut short. My iPhone shows the audio signal coming in but no transcription text appears. I am using try latest version 2.7.0. I had hoped to use the transcription on my phone only and dedicate my iPad to ForeFlight navigation and weather.

Doesn’t work on iPhone

It works great if it works. But it work on my iPad, but doesn't work on iPhone and other iPad. The app shows green audio input, but the text doesn’t appear.

Broken

Stratus connects fine to ForeFlight, but stratus horizon pro can never see the device from my iPad nor iPhone.
