# iNavX vs Coordinates Calculator Pro

The clearest difference is price: iNavX at Free against Coordinates Calculator Pro's $3.99. iNavX also leads on rating (4.8 vs 4.3) and update cadence (every 5 weeks vs every 25 months). Coordinates Calculator Pro's advantage is in-app purchases (none vs 11) and ads (none vs shown). On review sentiment, device support and iOS requirement there is nothing between them.

iNavX is free to download; Coordinates Calculator Pro costs $3.99 up front. iNavX sells 11 in-app purchases, starting at $9.99 per month. Coordinates Calculator Pro asks for nothing beyond the download.

iNavX holds the better App Store score, 4.8 against 4.3. That said, the two scores are not equally well evidenced: iNavX has 22K ratings behind it against 7, so its average is the more settled of the two. Written reviews complicate that: 44% of iNavX's written reviews are positive against 50% of Coordinates Calculator Pro's, so the app with the better star average is not the one people write more warmly about.

iNavX ships an update every 5 weeks, Coordinates Calculator Pro every 25 months. The most recent releases landed on October 18, 2026 and October 4, 2026 respectively.
