# Send SOS vs NumberBox

The clearest difference is rating: Send SOS at 5.0 against NumberBox's 4.5. NumberBox's advantage is ratings volume (565 vs 1) and update cadence (every 2 months vs every 7 months). 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.

Send SOS holds the better App Store score, 5.0 against 4.5. That said, the two scores are not equally well evidenced: NumberBox has 565 ratings behind it against 1, so its average is the more settled of the two. Written reviews complicate that: 50% of Send SOS's written reviews are positive against 61% of NumberBox's, so the app with the better star average is not the one people write more warmly about.

Send SOS ships an update every 7 months, NumberBox every 2 months. The most recent releases landed on November 2, 2026 and November 4, 2026 respectively.
