# Best Phone Security vs 4Warning

The clearest difference is rating: Best Phone Security at 4.6 against 4Warning's 1.5. Best Phone Security also leads on ratings volume (3K vs 2). 4Warning's advantage is ads (none vs shown) and update cadence (every 2 weeks vs every 3 months). On price, in-app purchases, monetization model and device support there is nothing between them.

Both are free to download. Best Phone Security sells 1 one-off in-app purchase and 4Warning sells 1 in-app purchase, starting at $3.99 per year. Whichever you choose, the download price is not the number that matters.

Best Phone Security holds the better App Store score, 4.6 against 1.5. That said, the two scores are not equally well evidenced: Best Phone Security has 3K ratings behind it against 2, so its average is the more settled of the two. Written reviews complicate that: 69% of Best Phone Security's written reviews are positive against 80% of 4Warning's, so the app with the better star average is not the one people write more warmly about.

Best Phone Security ships an update every 3 months, 4Warning every 2 weeks. The most recent releases landed on October 13, 2026 and October 4, 2026 respectively.
