# LightPlan vs GrayZone

The clearest difference is price: LightPlan at Free against GrayZone's $2.99. LightPlan also leads on rating (4.6 vs 2.8) and device support (3 vs 1). GrayZone's advantage is in-app purchases (none vs 3) and update cadence (weekly vs every 3 weeks). On review sentiment, ratings volume and ads there is nothing between them.

LightPlan is free to download; GrayZone costs $2.99 up front. LightPlan sells 3 in-app purchases, starting at $2.99 per month. GrayZone asks for nothing beyond the download.

LightPlan holds the better App Store score, 4.6 against 2.8. Both are backed by a comparable volume of ratings — 10 and 5 respectively. Written reviews complicate that: 57% of LightPlan's written reviews are positive against 63% of GrayZone's, so the app with the better star average is not the one people write more warmly about.

LightPlan ships an update every 3 weeks, GrayZone weekly. Both last shipped on October 25, 2026.
