# Authenticator Duo vs QR Code Pro

The clearest difference is monetization model: QR Code Pro at free with in-app purchases against Authenticator Duo's subscription. Authenticator Duo's advantage is ratings volume (14 vs 1) and iOS requirement (15.0 vs 17.0). On price, rating, update cadence and ads there is nothing between them.

Both are free to download. Authenticator Duo sells 2 in-app purchases, starting at $6.99 per 7 days and QR Code Pro sells 2 in-app purchases, starting at $6.99 per 7 days. Whichever you choose, the download price is not the number that matters.

On the App Store both sit at effectively the same score — 5.0 for Authenticator Duo against 5.0 for QR Code Pro. That said, the two scores are not equally well evidenced: Authenticator Duo has 14 ratings behind it against 1, so its average is the more settled of the two.

Both ship on a similar rhythm, roughly every 2 days. The most recent releases landed on September 15, 2026 and September 30, 2026 respectively.
