# SMS Alert vs JBD BMS

The clearest difference is rating: SMS Alert at 4.0 against JBD BMS's 3.1. SMS Alert also leads on iOS requirement (9.0 vs 15.0). JBD BMS's advantage is update cadence (every 3 weeks vs every 14 months) and review sentiment (23% vs 0%). On price, ads, in-app purchases and monetization model there is nothing between them.

Both are free to download. Neither carries in-app purchases, so what you see is what you pay.

SMS Alert holds the better App Store score, 4.0 against 3.1. That said, the two scores are not equally well evidenced: JBD BMS has 26 ratings behind it against 2, so its average is the more settled of the two. Written reviews complicate that: 0% of SMS Alert's written reviews are positive against 23% of JBD BMS's, so the app with the better star average is not the one people write more warmly about.

SMS Alert ships an update every 14 months, JBD BMS every 3 weeks. The most recent releases landed on July 7, 2026 and September 23, 2026 respectively.
