# Avira Mobile Security vs Bitdefender Mobile Security

The clearest difference is rating: Bitdefender Mobile Security at 4.7 against Avira Mobile Security's 4.3. Bitdefender Mobile Security also leads on update cadence (weekly vs monthly) and chart position (#197 vs unranked). Avira Mobile Security's advantage is review sentiment (67% vs 46%). On price, ads, in-app purchases and monetization model there is nothing between them.

Both are free to download. Avira Mobile Security sells 10 in-app purchases, starting at $1.99 per month and Bitdefender Mobile Security sells 8 in-app purchases, starting at $3.99 per month. Whichever you choose, the download price is not the number that matters.

Bitdefender Mobile Security holds the better App Store score, 4.7 against 4.3. That said, the two scores are not equally well evidenced: Bitdefender Mobile Security has 37K ratings behind it against 4.6K, so its average is the more settled of the two. Written reviews complicate that: 67% of Avira Mobile Security's written reviews are positive against 46% of Bitdefender Mobile Security's, so the app with the better star average is not the one people write more warmly about.

Avira Mobile Security ships an update monthly, Bitdefender Mobile Security weekly. The most recent releases landed on September 23, 2026 and September 25, 2026 respectively.
