Xavion vs iEFIS Pro
Price, ratings, monetisation and update history for both apps, side by side — with what reviewers say about each.
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.

i-EFIS simulates a modern glass cockpit for general aviation and provides the following features: 1. Display iOS iPhone and iPad sensor data: The attitude indicator is driven by the 3D MEMS chip, speed and altitude come from the internal or external GPS (only iOS devices with cellular connection have the integrated GPS!) 2. Or connect the iPhone to a iLEVIL „SW“, „AW“ or „Sport“ device (available at the LEVIL company or in many pilot shops) by WIFI device to get precise attitude and GPS data. 3. A 80 or 360 degree course rose (change with tap on airplane symbol) 4. Magnetic and True GPS track (display in white with with track line) 5. Magnetic or True Heading, heading data is provided by internal compass and is not always reliable. 6. iEFIS Pro version (simple upgrade via inapp purchase!) displays a worldwide airport database and always shows the bearing to the nearest airport from your position with distance, elevation and runway orientation of the main runway of that airport. How to use i-EFIS 1. Tap the speed window to toggle speed units: km/h - mph - knots. Speed displayed is a GPS ground speed 2. Tap on the altitude window to switch from feet MSL to Meters MSL 3. Tap the course window to select the course mode: Magnetic Heading - True Heading - Magnetic Track - True Track. All GPS track modes are displayed in white, heading modes are yellow 4. Tap the airplane symbol to display either the full 360 degree course rose or a 80 degree segment Pro version features 1. Tap on Runway orientation info to see runway length 2. Tap course window and slide up to hide attitude indicator and to switch to full screen mode 3. To calibrate magnetic heading tap course window to show "HDG" (Magnetic Heading), and slide finger left or right to set correct heading. Use airplane's compass as reference 4. To select a different airport than the nearest one simply tap on the airport symbol and the app will display the data for this airport 5. To go back to the nearest airport simply tap the empty space between the airports Airport database in Pro version: 1. Switch Airport database on or off in settings. 2. Use the two finger pinch gesture to zoom airport map in/out More cool Features coming! Terms of Use: https://www.apple.com/legal/internet-services/itunes/dev/stdeula/

Verdict
The clearest difference is rating: iEFIS Pro at 5.0 against Xavion's 4.3. iEFIS Pro also leads on review sentiment (100% vs 70%). Xavion's advantage is update cadence (every 4 days vs every 3 weeks) and ratings volume (100 vs 3). On price, ads, in-app purchases and monetization model 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 and iEFIS Pro sells 1 in-app purchase, starting at $2.99 per month. Whichever you choose, the download price is not the number that matters.
iEFIS Pro holds the better App Store score, 5.0 against 4.3. 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: 70% of Xavion's written reviews are positive against 100% of iEFIS Pro's.
Xavion ships an update every 4 days, iEFIS Pro every 3 weeks. The most recent releases landed on November 1, 2026 and November 8, 2026 respectively.
