# Authenticator App vs AI Email Writer

The clearest difference is review sentiment: AI Email Writer at 84% against Authenticator App's 29%. AI Email Writer also leads on rating (4.8 vs 4.4) and update cadence (every 4 days vs every 2 weeks). Authenticator App's advantage is ads (none vs shown). On price, in-app purchases, monetization model and device support there is nothing between them.

Both are free to download. Authenticator App sells 6 in-app purchases, starting at $4.19 per 7 days and AI Email Writer sells 6 in-app purchases, starting at $6.99 per 7 days. Whichever you choose, the download price is not the number that matters.
