Verdict
The clearest difference is rating: Alarm.com at 4.7 against ADT Alert's 4.3. Alarm.com also leads on update cadence (every 4 weeks vs every 5 months) and ratings volume (141K vs 67). ADT Alert's advantage is review sentiment (31% vs 23%) and iOS requirement (9.0 vs 17.0). 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.
Alarm.com holds the better App Store score, 4.7 against 4.3. That said, the two scores are not equally well evidenced: Alarm.com has 141K ratings behind it against 67, so its average is the more settled of the two. Written reviews complicate that: 23% of Alarm.com's written reviews are positive against 31% of ADT Alert's, so the app with the better star average is not the one people write more warmly about.
Alarm.com ships an update every 4 weeks, ADT Alert every 5 months. The most recent releases landed on October 19, 2026 and October 17, 2026 respectively.
