Backup Glass Cockpit on your iPad Stratus Horizon Pro displays a complete Attitude Heading Reference System (AHRS) for supplemental attitude information in your cockpit. Driven by a Stratus receiver, the AHRS feature will display a super responsive pitch and bank instrument on your iPad. It aligns itself automatically, so you can just turn it on and fly. This provides an excellent backup for emergency situations. Radio Transcription & Playback Plug in and play back. You’ll never have to say “say again” again when you use the radio playback feature. Plug in a Stratus Audio Cable to capture ATC communications for easy one-touch playback. Similar to how visual voicemail works, the ATC communications will be converted into text, providing a visual assist for referencing previous audio clips for playback. This enables pilots to receive a clearance, ATIS, or other important ATC communications without needing to write them down Stratus Audio Cable The Stratus Audio Cable (available to purchase for $49.99 from the Appareo web store) is needed to enable the radio transcription and playback feature. No cellular service or internet connection is required to operate the app. Stratus Device Management Download firmware updates for all models of Stratus portable ADS-B receivers, Stratus 1, 2, 1S, 2S, 2i, 3, 3i, and 4. Switch your Stratus 3 to "Open ADS-B Mode" to utilize its GDL-90 protocol that integrates Stratus with most flight apps. Stratus 4 defaults to GDL-90 mode. Enable notifications to get updates any time there is a firmware update to your portable device. Stratus Horizon Pro is a flight app that can be viewed in day mode, night mode, or via heads-up display. App Multitasking Stratus Horizon Pro supports app multitasking with split view and overlay view, so you can use radio transcription and playback alongside your favorite EFB. The EFB app must be able to support multitasking. ## Key features - Backup Attitude Heading Reference System (AHRS) - Responsive pitch and bank instrument display - Automatic AHRS alignment - Radio transcription and playback of ATC communications - Visual assist for referencing audio clips - Firmware updates for Stratus receivers - Day, night, and heads-up display modes ## Pricing and in-app purchases Base price: Free. **Subscriptions** | Subscription | Price | Period | | --- | --- | --- | | ATC Transcription - Monthly | $4.99 | per month | | ATC Transcription - Yearly | $49.99 | per year | ## Recent user reviews (10 of 12) All indexed reviews: https://appshunter.io/ios/app/stratus-horizon-pro/id1001279833/reviews.md ### 1/5 — Don’t transcribe ATC well at all *2024-01-08* 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! ### 5/5 — Great App *2022-11-03* 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. ### 3/5 — Works on iPad but not my iPhone *2021-11-17* 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. ### 4/5 — Doesn’t work on iPhone *2021-08-09* 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. ### 1/5 — Broken *2020-09-21* Stratus connects fine to ForeFlight, but stratus horizon pro can never see the device from my iPad nor iPhone. ### 5/5 — Please advise on current status *2020-03-28* Hi , I purchased the straus 3 with the audio cable, and downloaded the application, Unfortunately I couldn’t figure out how to make it work, It’s not recording or give any transcription , Last update says the application is now function with both features ., Please advise . Thank you **Developer response:** Hello. A couple things could be affecting the app performance - we recommend you have the most recent iOS version on your device and that you make sure your app is up to date as well. There are also some devices that Stratus Horizon Pro does not support: iPad 3 and older, iPad mini 3 and older, iPhone 5S and older, iPad Air 1 (transcriptions will not work, only audio playback), and iPod Touch 4 and older. Please directly reach out to support@appareo.com for further assistance - we would love for you to give the app another try. ### 2/5 — Dictation doesn’t work as promised *2019-12-23* Bought the cable as well, expecting to read ATC off the app as advertised but it simply doesn’t work **Developer response:** Thank you for downloading the app and purchasing the Stratus Audio cable. The current app only has radio playback, transcriptions is still in development with an expected release March 2020. ### 4/5 — When is transcription coming? *2019-12-12* I have had the app loaded and purchased the cable many months ago with the anticipation of the transcription being released soon as stated on the web site. When is soon? **Developer response:** Transcriptions are still in testing but expected to be available in March 2020 ### 1/5 — Crash on every use *2019-09-20* When I try and update my Stratus 3 the app crashes every time. ### 1/5 — Hasn’t worked since last Apple update *2018-10-30* I have I phone 6 and iPad mini 2 which runs my Foreflight. Appareo Systems was notified a month ago that app won’t open since Apple last update. I have emails that indicate a fix was being worked on but still no joy. App won’t open. Good luck with it. ## Frequently asked questions about Stratus Horizon Pro ### Does Stratus Horizon Pro have ads? No, Stratus Horizon Pro does not contain advertisements.
