The Best Notes App That Works Offline

A notes app that needs Wi·Fi to open is not a notes app. What real offline support looks like.

What "works offline" really means

It is a three·part test:

Read offline· Can you open the app and see every note without a connection?
Write offline· Can you create and edit notes, and trust they will sync later?
Search offline· Can you actually find a note when there is no server to query?

Notion fails #1·it shows a loading spinner. Google Keep partially fails #3·search becomes hit·or·miss. Evernote requires a paid plan for offline access on mobile.

Apps that pass all three

[Obsidian](/alternatives/obsidian)· Local files on disk. Offline is the default state.
Apple Notes· Strong on Apple devices, locally cached.
[SimplyBoard](/features/offline-support)· Encrypted local cache, full search and edit offline, automatic sync on reconnect.
Bear· Apple·only, fully offline·capable.
Joplin· Local·first markdown with optional sync.

The hidden requirement: conflict handling

Offline support is easy to claim until two devices edit the same note while disconnected. Then it gets ugly:

Obsidian creates "conflict" files you resolve manually.
Apple Notes silently picks a winner·sometimes the wrong one.
SimplyBoard uses last·write·wins by design, with no conflict UI to manage. Simple, predictable.

There is no perfect answer. Pick the trade·off you can live with.

Why offline matters more than you think

It is not just planes and tunnels. It is the cafe with bad Wi·Fi. The hotel that wants $15/day. The moment your VPN drops. The interview question you want to write down before you forget it.

An app that works only when the network does is a notes app that works only when convenient·which is exactly when you don't need it.

Our pick

SimplyBoard is built offline·first: the entire encrypted cache lives in your browser's IndexedDB, search runs on·device, and edits are queued and synced the moment the connection returns. Read more about how we built it.

Write fast. Find faster.
Stay private.

The trusted, encrypted alternative to Notion, Trello, and Miro. A fast, private knowledge base for developers, founders, and power users who need to store and retrieve information without friction · encrypted, searchable, and offline-ready.

No credit card required. Free for personal use.

Everything you need, nothing you don't

Most tools overwhelm you with dashboards and settings you never touch. SimplyBoard gives you fast, encrypted storage that works the way you think. Every feature helps you store or retrieve information faster.

Instant Search

Full-text fuzzy search across all entries · find any snippet or command in milliseconds, even with typos.

Client-Side Encryption

Your data is encrypted with AES-GCM before it leaves your device. We never see your content.

Multiple Workspaces

Separate encrypted spaces for work, personal projects, and side ventures · each context distinct and focused.

Keyboard-First

Navigate, search, and manage entries entirely from your keyboard without breaking your flow.

Cross-Device Sync

Encrypted entries sync across all your devices, giving you instant access to your knowledge base anywhere.

Offline Support

Works fully offline. All changes sync automatically in the background when you reconnect.

How it works

1. Capture anything

Paste a command, save a snippet, or jot a note. Each entry supports plaintext or Markdown · no rigid templates.

2. Find it instantly

Type in the search bar and results appear instantly with fuzzy matching. Frequently accessed entries naturally rise to the top.

3. Stay in control

Everything is encrypted on your device before syncing. Works offline, no folders required, no lock-in.

Your data, your control

SimplyBoard uses AES-256-GCM encryption with PBKDF2 key derivation (100,000 iterations). Every entry is encrypted before it leaves your device. Our servers store only ciphertext · we cannot read your data under any circumstances. Even if our database were compromised, your data remains unreadable without your password or passphrase.

Zero-knowledge architecture

✓ SOC 2 Type 2 Infrastructure ✓ ISO 27001:2022 Infrastructure ✓ GDPR Compliant

Frequently Asked Questions

Is SimplyBoard really free?

Yes! SimplyBoard is free for personal use. We believe everyone deserves access to a private, secure knowledge base.

How does client-side encryption work?

Your password (or passphrase for Google sign-in) is used to derive an encryption key using PBKDF2 with 100,000 iterations. All your entries are encrypted with AES-GCM before leaving your device. We never see your decrypted data·not even our servers can read it.

How does encryption work with Google sign-in?

After signing in with Google, you create a separate encryption passphrase. This passphrase works exactly like a password for encryption·it derives the key that protects your data. Your Google account only handles authentication, not encryption. We cannot recover your passphrase or open your vault without it.

Can I switch between email and Google sign-in?

No. Once you register with a specific method (email/password OR Google), you must continue using that same method. Each method uses a different encryption key derivation, so they cannot be interchanged.

What happens if I forget my password or passphrase?

Because of our zero-knowledge architecture, we cannot recover your password or passphrase, or decrypt your data. This is by design·it ensures that only you can access your information. We recommend storing your password or passphrase in a secure password manager. Your account will be deleted after 90 consecutive days of inactivity.

What is the 90-day inactivity policy?

Accounts that are not accessed for 90 consecutive calendar days will be permanently deleted without notice. This helps us manage storage costs and keeps the platform lean.

Can I use SimplyBoard offline?

Yes! SimplyBoard works fully offline. Your entries are cached locally and sync automatically when you reconnect to the internet.

Is my data backed up?

Your encrypted data is stored securely in the cloud and synced across all your devices. The encryption ensures that even if someone accessed the server, they couldn't read your content.

What makes SimplyBoard different from Trello, Miro, or Notion?

SimplyBoard is built for speed and simplicity. No feature bloat, no expensive subscriptions, no learning curve. Just fast search, secure storage, and instant retrieval.

Can I self-host SimplyBoard?

Not currently. SimplyBoard is a cloud-hosted service to enable cross-device sync without you managing infrastructure. While your content is encrypted client-side, you are trusting us with metadata like your email and when entries are saved.
