Verdict

The call

The clearest difference is in-app purchases: NaAVIC at none against iNavX's 11. NaAVIC also leads on ads (none vs shown) and rating (5.0 vs 4.8). iNavX's advantage is ratings volume (22K vs 1) and update cadence (every 5 weeks vs every 6 months). On price, device support and iOS requirement there is nothing between them.

Both are free to download. iNavX sells 11 in-app purchases, starting at $9.99 per month. NaAVIC asks for nothing beyond the download.

ReceptionRating · Positive reviews · Number of ratings

NaAVIC holds the better App Store score, 5.0 against 4.8. That said, the two scores are not equally well evidenced: iNavX has 22K ratings behind it against 1, so its average is the more settled of the two. Written reviews complicate that: 44% of iNavX's written reviews are positive against 33% of NaAVIC's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

iNavX ships an update every 5 weeks, NaAVIC every 6 months. The most recent releases landed on October 19, 2026 and October 1, 2026 respectively.
