# NightVision vs Ghost SLS

The clearest difference is price: NightVision at Free against Ghost SLS's $0.99. NightVision also leads on review sentiment (50% vs 37%). Ghost SLS's advantage is rating (4.4 vs 3.8) and update cadence (every 2 months vs every 16 months). On ads, in-app purchases, monetization model and device support there is nothing between them.

NightVision is free to download; Ghost SLS costs $0.99 up front. Neither carries in-app purchases, so what you see is what you pay.

Ghost SLS holds the better App Store score, 4.4 against 3.8. That said, the two scores are not equally well evidenced: Ghost SLS has 3.6K ratings behind it against 19, so its average is the more settled of the two. Written reviews complicate that: 50% of NightVision's written reviews are positive against 37% of Ghost SLS's, so the app with the better star average is not the one people write more warmly about.

NightVision ships an update every 16 months, Ghost SLS every 2 months. The most recent releases landed on October 1, 2026 and October 14, 2026 respectively.
