Markov Algorithm vs Cipher
Price, ratings, monetisation and update history for both apps, side by side — with what reviewers say about each.
Markov Algorithm
This tool emulates a Markov Machine, a string rewriting system used in computer science. It helps students test and debug algorithms with grammar-like rules and a step-by-step execution log.
- Markov Machine emulator
- String rewriting system
- Grammar-like rule application
- Step-by-step debugging
- Execution log

Students of computer science are probably familiar with Markov algorithm. A string rewriting system that uses grammar-like rules to operate on strings of symbols. This application is a great Markov Machine emulator which can help you test your algorithms and debug it step-by-step using convenient execution log.

Cipher
Securely store and encrypt sensitive text files, passwords, and crypto keys. Access your protected information across devices with cloud sync, even when offline. Your data remains private and under your control with strong AES-based encryption.
- Encrypt notes, texts, passwords, crypto keys, and recovery phrases
- Import text files for encryption
- Search across encrypted items
- Cloud Sync across devices
- Offline access to encrypted content
- AES-based encryption

Password managers ask you to trust them with everything. One breach — and your whole digital life is exposed. Cipher works differently: you store hints, not passwords. The passwords stay in your head. HOW IT WORKS Keep two or three base patterns in your head. They are never written down anywhere. For each service, save only a hint about which pattern and which rule you used: "Bank — pattern B, caps, +2024" That hint is useless to anyone else. The password itself never leaves your head. WHAT YOU GET - Hints, notes and text files encrypted with AES, each protected by a passphrase you choose - Passphrases are never stored — not on the device, not in the cloud - Works fully offline, no account required - Optional cloud sync with your Apple or Google account, if you want your hints on every device - Import text files, search across your encrypted items - Also fits crypto seed-phrase hints and any private note WHO IT IS FOR People who do not want to hand every password to a single vault. If you have hundreds of random passwords, a password manager is the right tool. If you rely on patterns in your head and keep forgetting which rule you used where, Cipher is for you.

Verdict
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.
