Metion is a notebook tool that focuses on the writing experience, uses Markdown as basic text syntax. ## Build Your Own Knowledge Base Metion 2.0 brings a new feature named "Knowledge Base", the plain text syntax, then becomes mindmap trees, or connected as a network... ## The Writing Experience is So Important Our goal is to create a great writing experience, specially for iPadOS, although it's not easy. Metion provides a relatively complete keyboard shortcuts support. After a keyboard connected, both iPad and iPhone can archive a huge improvement in writing experience. We also have redesigned the "Zen Mode" on iPad, a more focusing writing mode. It is very very beautiful, choosing a suitable background image, selecting the white noise you like in Zen Mode, and the irrelevant UI elements are hidden. Writing is a pleasure, writing is talking to the world, writing is your Zen. ## Data Freedom, Open Filesystem, Git Built-in Metion based on the open filesystem, no need to create another new format for storing data. An article is a plain text file, and the images in the article are also under a certain folder. Data freedom and open filesystems allow us to synchronize data across devices using iCloud or Git. If you have a higher requirement for data security, you can also make a backup very quickly by copying the entire folder (working directory). One more thing, Metion has a built-in support named "history version" that provides a little more reliability for your documents. **Also, if you know how to use Git, you can try Git to sync. Yes! We have the powerful Git as a built-in feature! ** ## Optimized for iPad Pro, Also for iPhone We tried the best to make Metion optimized for iPad Pro, when writing on iPad Pro by Metion, the iPad is a really more productive device. Metion is also optimized for the iPhone too. In recent years, most of the new iPhones have notch at the top of screen. Metion does not simply avoid the safe area, but makes a lot of technical efforts to apply every pixel on the screen as far as possible. If using the visual theme of "Dark", the notch sometimes look like disappeared, like the next generation of full-screen phone comes. ## The Exporting of Metion If using Metion to export as PDF, we suggest the theme of PDF can be set as "Printer" in Settings Panel. If there is a real printer connected in current local network, just print directly, it will be pretty when words on the real paper. Document in Metion can be exported as image, which is optimized for mobile device (iPhone). We can set text and QR-Code signature at the end of exported image. Send it to friends through some social Apps. The beautiful layout of text can highlight the value of your words. Metion can analyze the structure of current article automatically, then export it as "Mindmap" with one tap only. - - - - - - - - - - Privacy Policy: http://markeditor.com/privacy-policy.html Terms of Use: http://markeditor.com/page/terms.md

Your passwords are only ever unlocked on your own devices. Your vault is encrypted on your iPhone and computer; our servers hold no copy of it and cannot see inside. Buy the current major version once, get free updates within it, and never create an account. YOUR VAULT STAYS WITH YOU · Encryption and decryption happen on your device; your master password is never stored or uploaded · Sync across devices through a place you choose: WebDAV, iCloud Drive, Dropbox, a local folder on your computer, or another device on the same Wi-Fi. Only the encrypted vault is transferred · Works offline for viewing, copying and adding entries BUY ONCE, NOT A SUBSCRIPTION · Pay once, use the current major version with free updates · Buy a lifetime license for 1, 3 or 5 devices in the app; owners can add devices by paying the difference · No account needed; use Restore Purchase on a new iPhone SEE WHAT AI READ Connect an AI coding assistant on your computer and decide item by item what it may read. Every read is logged: which assistant, which item, and when. After sync, the AI Access center on your iPhone shows it all, and you can revoke everything in one tap. Each item can be set to "use but can't see": the AI can use it without seeing the secret itself, and newly shared items default to this. While your computer is locked, AI requests go to your iPhone, where you can allow just that one, allow for a set time, or deny. Items you have not shared stay invisible to AI. MOVE FROM APPLE PASSWORDS In Passwords, choose Export Data to Another App → RootKey. Passwords, passkeys and verification codes are handed over by the system directly, with no server in between. SIRI AND SHORTCUTS Say "Search RootKey" or "Lock RootKey" to jump straight there. Shortcuts only open the app and never read out or return a password; you still unlock as usual. WHAT YOU GET · 19 item types: logins, credit cards, bank accounts, identity documents, Wi-Fi, servers, SSH keys and more, plus custom fields · Photograph the label on your router and the Wi-Fi name and password fill in · Keep work and personal items in separate vaults; a vault deleted by mistake can be restored from the Trash · Strong password generator with adjustable length and character sets · One-time codes (TOTP) right next to the password, filled into verification code fields automatically · Strong passwords generated and saved when you sign up; insert server addresses, tokens and card numbers into any text field · System-level autofill and passkeys · Security check: weak, reused and breached passwords, missing 2FA, expiring cards and documents · Passwords copied to the clipboard clear themselves automatically FORGOT YOUR MASTER PASSWORD? THERE IS A WAY BACK Creating a vault generates a recovery key and walks you through printing it. If you forget your master password, the key resets it without losing data. If both are lost, nobody can open the vault, including us, so keep it safe. OPEN SOURCE CRYPTO CORE Every line that touches your passwords and keys is published at github.com/bitbeam-cn/rootkey-crypto (MIT / Apache-2.0) with test vectors anyone can check. Security depends on your master password, not on the code being secret. TRIAL Try every feature free for 14 days, no sign-up. When it ends you can still view, copy and export everything; only adding and editing are limited. Support: hi@bitbeam.cn Website: rootkey.bitbeam.cn

Verdict
The clearest difference is rating: RootKey at 5.0 against Metion's 4.3. RootKey also leads on review sentiment (100% vs 60%) and update cadence (daily vs fortnightly). Metion's advantage is ratings volume (46 vs 1) and monetization model (free with in-app purchases vs paid). On price, ads, in-app purchases and device support there is nothing between them.
Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS
Both are free to download. Metion sells 3 in-app purchases, starting at $0.99 per month and RootKey sells 6 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.
RootKey holds the better App Store score, 5.0 against 4.3. That said, the two scores are not equally well evidenced: Metion has 46 ratings behind it against 1, so its average is the more settled of the two. Written reviews point the same way: 60% of Metion's written reviews are positive against 100% of RootKey's.
Metion ships an update fortnightly, RootKey daily. The most recent releases landed on November 3, 2026 and October 31, 2026 respectively.
