AHRS Utility vs Xavion
Price, ratings, monetisation and update history for both apps, side by side — with what reviewers say about each.
AHRS Utility
This app configures and displays data from Levil AHRS devices for pilots. It presents attitude, heading, and air data graphically and numerically, but is not a primary flight display.
- Configure Levil devices
- Display AHRS data graphically
- Display AHRS data numerically
- View air data (model dependent)
- View engine data (compatible systems)

AHRS utility is a free application designed to configure Levil devices before flight and to display Levil's AHRS data graphically and numerically. This application is only compatible with the Attitude and Heading Reference System from Levil Technology, model AHRS G mini, iLevil series and BOM series. Users must be connected to the wireless network of the Levil AHRS. The application will NOT display airplane attitude based on the internal gyros of your iPad/iPhone or GPS data. AIR DATA: Air data is only available on the AW model or BOM. If you have an iLevil SW, Air data will be derived from the internal GPS on the iLevil. Engine: You must have a compatible engine information system connected to the iLevil to display this information. This application is not meant to be used as a Primary Flight Display or for IFR flight.
Xavion
This app provides critical in-flight guidance for engine failures, calculating safe glide routes to airports. It also offers 3D instrument approaches, tracks aircraft and their wake turbulence, and displays real-time weather data. Additionally, it assists with pre-flight planning, weight and balance calculations, and takeoff performance analysis.
- Engine-out glide path calculation
- 3D instrument approaches
- ADS-B aircraft and wake turbulence tracking
- Real-time ADS-B weather display
- Weight and balance calculations
- Takeoff distance estimation
- Enroute time and fuel burn estimation

In flight, Xavion constantly imagines engine-failed glides to every runway in gliding range, and then shows you the safest-possible route as a Highway-In-The-Sky to take to an airport in the event of engine failure. This, finally, gives you guidance after an engine failure that is based on energy-management all the way down. Xavion also has instrument approaches in 3-D for the United States, so you can simply select any approach and then fly through the hoops to fly it! As well, Xavion tracks other airplanes via ADS-B, and memorizes their location to track their WAKE TURBULENCE, moving the wake turbulence down and with the wind over time, showing the wake turbulence as little spiraling tornados. Finally, an App that tracks and shows you the wake turbulence of other airplanes. As well, Xavion gets ADS-B weather if you have a portable receiver, and displays it, including the new icing, turbulence, and lightning products. Xavion also gets METARS and winds aloft from the internet if you have a WIFI or cell signal to help you plan before a flight! Also, Xavion checks your weight and balance, and even estimates your takeoff distance and compares that to the length of the runway that you are about to take off on to warn you if the available runway length from your current location is marginal for a safe take-off. Also, Xavion estimates time and fuel burn at all different altitudes to any destination, showing you the time and fuel burn required for each altitude enroute, so you can pick the best altitude. All USA VFR and IFR charts and plates are included with base subscription.

Verdict
The clearest difference is rating: Xavion at 4.3 against AHRS Utility's 3.0. Xavion also leads on update cadence (every 4 days vs every 2 months) and review sentiment (70% vs 50%). AHRS Utility's advantage is in-app purchases (none vs 2) and iOS requirement (9.0 vs 15.0). On price, ads and device support there is nothing between them.
Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS
Both are free to download. Xavion sells 2 in-app purchases, starting at $9.99 per month. AHRS Utility asks for nothing beyond the download.
Xavion holds the better App Store score, 4.3 against 3.0. That said, the two scores are not equally well evidenced: Xavion has 100 ratings behind it against 3, so its average is the more settled of the two. Written reviews point the same way: 50% of AHRS Utility's written reviews are positive against 70% of Xavion's.
AHRS Utility ships an update every 2 months, Xavion every 4 days. Both last shipped on November 1, 2026.
