# iAntiTheft vs Security Alarm

The clearest difference is ads: iAntiTheft at none against Security Alarm's shown. iAntiTheft also leads on rating (4.6 vs 4.3) and review sentiment (65% vs 55%). Security Alarm's advantage is update cadence (every 3 weeks vs every 2 months). On price, ratings volume, in-app purchases and monetization model there is nothing between them.

Both are free to download. iAntiTheft sells 1 one-off in-app purchase and Security Alarm sells 2 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.

iAntiTheft holds the better App Store score, 4.6 against 4.3. Both are backed by a comparable volume of ratings — 1.2K and 526 respectively. Written reviews point the same way: 65% of iAntiTheft's written reviews are positive against 55% of Security Alarm's.
