# Nautilus GPS vs NetSpot WiFi Analyzer

The clearest difference is rating: NetSpot WiFi Analyzer at 3.7 against Nautilus GPS's 1.9. NetSpot WiFi Analyzer also leads on update cadence (every 2 weeks vs every 21 months) and ratings volume (354 vs 12). Nautilus GPS's advantage is in-app purchases (none vs 3) and review sentiment (25% vs 15%). On price, ads, device support and iOS requirement there is nothing between them.

Both are free to download. NetSpot WiFi Analyzer sells 3 in-app purchases, starting at $8.99 per month. Nautilus GPS asks for nothing beyond the download.

NetSpot WiFi Analyzer holds the better App Store score, 3.7 against 1.9. That said, the two scores are not equally well evidenced: NetSpot WiFi Analyzer has 354 ratings behind it against 12, so its average is the more settled of the two. Written reviews complicate that: 25% of Nautilus GPS's written reviews are positive against 15% of NetSpot WiFi Analyzer's, so the app with the better star average is not the one people write more warmly about.

Nautilus GPS ships an update every 21 months, NetSpot WiFi Analyzer every 2 weeks. The most recent releases landed on October 24, 2026 and October 26, 2026 respectively.
