# Kidde vs Meross

The clearest difference is review sentiment: Meross at 77% against Kidde's 44%. Meross also leads on update cadence (fortnightly vs every 2 months). Kidde's advantage is rating (4.7 vs 4.5). On price, ratings volume, ads and in-app purchases there is nothing between them.

Both are free to download. Kidde sells 2 in-app purchases, starting at $1.99 per month and Meross sells 8 in-app purchases, starting at $0.99 per month. Whichever you choose, the download price is not the number that matters.

Kidde holds the better App Store score, 4.7 against 4.5. Both are backed by a comparable volume of ratings — 6.7K and 7.9K respectively. Written reviews complicate that: 44% of Kidde's written reviews are positive against 77% of Meross's, so the app with the better star average is not the one people write more warmly about.

Kidde ships an update every 2 months, Meross fortnightly. Both last shipped on October 15, 2026.
