## Description

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.

## Review summary

Reviews show the app has strong promise and helpful firmware update capabilities, plus reliable hardware. However, transcription reliability and cross-device inconsistencies, along with frequent stability issues (crashes and launch failures) and delayed feature delivery, dominate user concerns.

### Pros

- Firmware update capability improves functionality and fixes issues (noted in multiple reviews).
- The app concept is promising and could be a lifesaver for pilots.
- Stratus hardware (e.g., Stratus 2s) shows long-term reliability (years with no issues).

### Cons

- Transcriptions are unreliable and inconsistent across devices, with misses and missing text.
- Transcription feature not delivered or functioning as advertised; some reviews indicate delays or incomplete implementation.
- App crashes during updates and won't open after OS updates.
