# Nautilus vs pScanner

The clearest difference is ratings volume: Nautilus at 3.2K against pScanner's 150. pScanner's advantage is review sentiment (63% vs 48%) and iOS requirement (16.0 vs 26.0). On price, rating, update cadence and ads there is nothing between them.

Both are free to download. Nautilus sells 3 in-app purchases, starting at $3.99 per month and pScanner sells 8 in-app purchases, starting at $3.99 per 7 days. Whichever you choose, the download price is not the number that matters.

On the App Store both sit at effectively the same score — 4.6 for Nautilus against 4.6 for pScanner. That said, the two scores are not equally well evidenced: Nautilus has 3.2K ratings behind it against 150, so its average is the more settled of the two. Written reviews are what separate them: 48% of Nautilus's written reviews are positive against 63% of pScanner's.

Nautilus ships an update every 11 days, pScanner every 8 days. The most recent releases landed on November 14, 2026 and November 12, 2026 respectively.
