# HotSOS Mobile vs KNOW Mobile

The clearest difference is ratings volume: HotSOS Mobile at 58 against KNOW Mobile's 8. HotSOS Mobile also leads on iOS requirement (12.0 vs 15.6). KNOW Mobile's advantage is update cadence (every 2 months vs every 4 months). On price, rating, review sentiment and ads there is nothing between them.

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

KNOW Mobile holds the better App Store score, 2.8 against 2.6. That said, the two scores are not equally well evidenced: HotSOS Mobile has 58 ratings behind it against 8, so its average is the more settled of the two. Written reviews complicate that: 4% of HotSOS Mobile's written reviews are positive against 0% of KNOW Mobile's, so the app with the better star average is not the one people write more warmly about.

HotSOS Mobile ships an update every 4 months, KNOW Mobile every 2 months. The most recent releases landed on September 24, 2026 and June 28, 2026 respectively.
