Verdict
The clearest difference is update cadence: CaptionCall at fortnightly against Send SOS's every 7 months. CaptionCall also leads on ratings volume (3.7K vs 1) and review sentiment (75% vs 50%). Send SOS's advantage is rating (5.0 vs 4.8). On price, ads, in-app purchases and monetization model there is nothing between them.
Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS
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 4.8. That said, the two scores are not equally well evidenced: CaptionCall has 3.7K 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 75% of CaptionCall'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, CaptionCall fortnightly. The most recent releases landed on October 5, 2026 and October 13, 2026 respectively.
