Best Encrypted Note Apps for iPhone in 2026 (Honest Comparison)
A head-to-head comparison of the best encrypted note-taking apps for iPhone in 2026: Secure Notes, Standard Notes, Notesnook, Bear, and Apple Notes.
Quick answer: The strongest encrypted note apps on iPhone in 2026 are Secure Notes, Standard Notes, and Notesnook — all offer true end-to-end encryption with keys that never leave your device. Apple Notes and Bear are convenient but rely on Apple-managed iCloud keys, which means Apple can technically access your content under a lawful request.
Encrypted note apps compared
| App | Encryption | Biometric | Folder lock | Sync | Pricing |
|---|---|---|---|---|---|
| Secure Notes | AES-256 end-to-end | Face ID / Touch ID | Yes, per-folder password | Encrypted iCloud | Free, PRO optional |
| Standard Notes | XChaCha20-Poly1305 E2EE | Face ID / Touch ID | Tag-level, not folder | Proprietary encrypted sync | Free, paid tier |
| Notesnook | XChaCha20-Poly1305 E2EE | Face ID / Touch ID | Yes, vaults | Encrypted cross-platform | Free, paid tier |
| Bear | No E2EE (iCloud at-rest only) | Face ID / Touch ID | No | iCloud (Apple-managed keys) | Paid subscription |
| Apple Notes | Per-note password, AES | Face ID / Touch ID | Single Locked folder only | iCloud (Apple-managed keys) | Free, built-in |
Which encrypted note app should I pick?
Secure Notes— the most iPhone-native option. Face ID unlock, per-folder passwords, a 12-word recovery seed, and AES-256 end-to-end encryption. The fastest path from “I want my notes locked” to “my notes are locked,” without a desktop client to configure.
Standard Notes — cross-platform veteran with long-session trust, strong cryptography (XChaCha20-Poly1305), and tag-based organization. If you live across iOS, macOS, Windows, and Linux and want the same notes everywhere, it is the classic pick. Folder-style nesting is weaker than Secure Notes.
Notesnook — the newer open-source challenger. Strong E2EE, vault feature for locked folders, and an active development cadence. Interface is denser than Secure Notes and the iPhone app has caught up recently but is not as polished.
Bear — beautiful and writer-friendly, but the encryption story is weaker: iCloud stores notes with Apple-managed keys. Good for notes you want private but not strictly secret.
Apple Notes — built-in and free. Good enough for a single locked note or two. The single Locked folder means you cannot segment access, and Apple holds the keys, so it is not a match for high-stakes content.
How should I evaluate an encrypted note app?
- End-to-end vs at-rest only: E2EE means the keys stay on your device. At-rest only means the provider can read your content.
- Named cipher:AES-256, XChaCha20-Poly1305. Vague “bank-grade encryption” claims are a red flag.
- Recovery model: a user-held seed is stronger than a developer-held reset link.
- Granularity: per-note and per-folder passwords beat one global password for shared devices.
- Transparency: public privacy policy, named publisher, ideally a third-party security audit.
