# CipherNook vs PDF Guru Anki

The clearest difference is price: PDF Guru Anki at Free against CipherNook's $4.99. PDF Guru Anki also leads on review sentiment (93% vs 50%) and ratings volume (14 vs 1). CipherNook's advantage is in-app purchases (none vs 3) and rating (5.0 vs 4.7). On update cadence, ads, device support and iOS requirement there is nothing between them.

PDF Guru Anki is free to download; CipherNook costs $4.99 up front. PDF Guru Anki sells 3 in-app purchases, starting at $0.99 per month. CipherNook asks for nothing beyond the download.

CipherNook holds the better App Store score, 5.0 against 4.7. That said, the two scores are not equally well evidenced: PDF Guru Anki has 14 ratings behind it against 1, so its average is the more settled of the two. Written reviews complicate that: 50% of CipherNook's written reviews are positive against 93% of PDF Guru Anki's, so the app with the better star average is not the one people write more warmly about.

Both ship on a similar rhythm, roughly every 3 weeks. The most recent releases landed on October 6, 2026 and October 13, 2026 respectively.
