# NoiSee vs Bitdefender Central

The clearest difference is price: Bitdefender Central at Free against NoiSee's $0.99. Bitdefender Central also leads on in-app purchases (none vs 4) and update cadence (every 3 weeks vs every 5 months). On review sentiment, ads and device support there is nothing between them.

Bitdefender Central is free to download; NoiSee costs $0.99 up front. NoiSee sells 4 one-off in-app purchases. Bitdefender Central asks for nothing beyond the download.

Bitdefender Central holds the better App Store score, 4.8 against 4.5. That said, the two scores are not equally well evidenced: Bitdefender Central has 11K ratings behind it against 243, so its average is the more settled of the two. Written reviews complicate that: 65% of NoiSee's written reviews are positive against 59% of Bitdefender Central's, so the app with the better star average is not the one people write more warmly about.

NoiSee ships an update every 5 months, Bitdefender Central every 3 weeks. Both last shipped on November 6, 2026.
