# Authenticator App vs RealStamp

The clearest difference is rating: RealStamp at 5.0 against Authenticator App's 4.5. RealStamp also leads on update cadence (every 2 weeks vs every 4 months) and monetization model (free vs free with in-app purchases). Authenticator App's advantage is ratings volume (137 vs 1). On price, ads, in-app purchases and device support there is nothing between them.

Both are free to download. Authenticator App sells 3 in-app purchases, starting at $2.99 per 7 days and RealStamp sells 4 in-app purchases, starting at $9.99 per month. Whichever you choose, the download price is not the number that matters.

RealStamp holds the better App Store score, 5.0 against 4.5. That said, the two scores are not equally well evidenced: Authenticator App has 137 ratings behind it against 1, so its average is the more settled of the two.
