# Xavion vs iEFIS Pro

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.

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.
