# Authenticator App vs ChatGPT

The clearest difference is monetization model: ChatGPT at free with in-app purchases against Authenticator App's subscription. ChatGPT also leads on review sentiment (70% vs 43%) and ratings volume (11M vs 49K). Authenticator App's advantage is ads (none vs shown) and device support (5 vs 2). On price, update cadence and in-app purchases there is nothing between them.

Both are free to download. Authenticator App sells 11 in-app purchases, starting at $5.99 per 7 days and ChatGPT sells 8 in-app purchases, starting at $8.00 per month. Whichever you choose, the download price is not the number that matters.

ChatGPT holds the better App Store score, 4.8 against 4.6. That said, the two scores are not equally well evidenced: ChatGPT has 11M ratings behind it against 49K, so its average is the more settled of the two. Written reviews point the same way: 43% of Authenticator App's written reviews are positive against 70% of ChatGPT's.

Authenticator App ships an update every 10 days, ChatGPT weekly. Both last shipped on September 24, 2026.
