# SecEMS vs MosApp

The clearest difference is rating: MosApp at 4.7 against SecEMS's 3.8. MosApp also leads on update cadence (every 8 days vs every 2 months). SecEMS's advantage is review sentiment (63% vs 50%) and ratings volume (17 vs 3). On price, ads, in-app purchases and monetization model there is nothing between them.

Both are free to download. SecEMS sells 4 in-app purchases, starting at $0.99 per month and MosApp sells 6 in-app purchases, starting at $2.49 per month. Whichever you choose, the download price is not the number that matters.

MosApp holds the better App Store score, 4.7 against 3.8. That said, the two scores are not equally well evidenced: SecEMS has 17 ratings behind it against 3, so its average is the more settled of the two. Written reviews complicate that: 63% of SecEMS's written reviews are positive against 50% of MosApp's, so the app with the better star average is not the one people write more warmly about.

SecEMS ships an update every 2 months, MosApp every 8 days. The most recent releases landed on July 31, 2026 and September 19, 2026 respectively.
