# Markov Algorithm vs Cipher

The clearest difference is in-app purchases: Cipher at none against Markov Algorithm's 3. Cipher also leads on device support (4 vs 2). Markov Algorithm's advantage is update cadence (every 5 weeks vs every 4 months). On price, review sentiment, ads and iOS requirement there is nothing between them.

Both are free to download. Markov Algorithm sells 3 in-app purchases, starting at $3.99 per month. Cipher asks for nothing beyond the download.

Markov Algorithm ships an update every 5 weeks, Cipher every 4 months. The most recent releases landed on October 3, 2026 and October 10, 2026 respectively.
