# Zone Tool vs Lightme

The clearest difference is price: Lightme at Free against Zone Tool's $0.99. Lightme also leads on rating (4.8 vs 2.8) and update cadence (every 2 weeks vs every 38 months). Zone Tool's advantage is in-app purchases (none vs 8) and review sentiment (100% vs 75%). On ads there is nothing between them.

Lightme is free to download; Zone Tool costs $0.99 up front. Lightme sells 8 in-app purchases, starting at $2.99 per month. Zone Tool asks for nothing beyond the download.

Lightme holds the better App Store score, 4.8 against 2.8. That said, the two scores are not equally well evidenced: Lightme has 102 ratings behind it against 6, so its average is the more settled of the two. Written reviews complicate that: 100% of Zone Tool's written reviews are positive against 75% of Lightme's, so the app with the better star average is not the one people write more warmly about.

Zone Tool ships an update every 38 months, Lightme every 2 weeks. The most recent releases landed on September 21, 2026 and October 13, 2026 respectively.
