# AES Crypt vs Unlock PDF

The clearest difference is rating: Unlock PDF at 5.0 against AES Crypt's 2.8. Unlock PDF also leads on update cadence (every 2 months vs every 9 months). AES Crypt's advantage is ratings volume (28 vs 1). On price, review sentiment, ads and in-app purchases there is nothing between them.

Both are free to download. AES Crypt sells 2 in-app purchases, starting at $0.99 per year and Unlock PDF sells 4 in-app purchases, starting at $0.99 per 7 days. Whichever you choose, the download price is not the number that matters.

Unlock PDF holds the better App Store score, 5.0 against 2.8. That said, the two scores are not equally well evidenced: AES Crypt has 28 ratings behind it against 1, so its average is the more settled of the two. Written reviews point the same way: 42% of AES Crypt's written reviews are positive against 50% of Unlock PDF's.

AES Crypt ships an update every 9 months, Unlock PDF every 2 months. The most recent releases landed on August 27, 2026 and July 5, 2026 respectively.
