# Authenticator vs PDF Converter

The clearest difference is ads: Authenticator at none against PDF Converter's shown. PDF Converter's advantage is update cadence (every 2 days vs every 5 months) and rating (4.8 vs 4.6). On price, review sentiment, ratings volume and in-app purchases there is nothing between them.

Both are free to download. Authenticator sells 3 in-app purchases, starting at $6.99 per 7 days and PDF Converter sells 4 in-app purchases, starting at $12.99 per 7 days. Whichever you choose, the download price is not the number that matters.

PDF Converter holds the better App Store score, 4.8 against 4.6. Both are backed by a comparable volume of ratings — 61 and 138 respectively. Written reviews split almost evenly too, at 0% and 0% positive.

Authenticator ships an update every 5 months, PDF Converter every 2 days. Both last shipped on September 18, 2026.
