# EMFMeter vs Grass Identifier

The clearest difference is rating: EMFMeter at 4.7 against Grass Identifier's 4.3. EMFMeter also leads on iOS requirement (15.6 vs 18.5). Grass Identifier's advantage is review sentiment (75% vs 60%) and update cadence (monthly vs every 2 months). On price, ratings volume, ads and in-app purchases there is nothing between them.

Both are free to download. EMFMeter sells 3 in-app purchases, starting at $3.99 per 7 days and Grass Identifier sells 3 in-app purchases, starting at $7.99 per 7 days. Whichever you choose, the download price is not the number that matters.

EMFMeter holds the better App Store score, 4.7 against 4.3. Both are backed by a comparable volume of ratings — 98 and 49 respectively. Written reviews complicate that: 60% of EMFMeter's written reviews are positive against 75% of Grass Identifier's, so the app with the better star average is not the one people write more warmly about.

EMFMeter ships an update every 2 months, Grass Identifier monthly. The most recent releases landed on October 16, 2026 and September 25, 2026 respectively.
