MemoKey keeps your text snippets, saved replies and message templates on your keyboard. Save a reply once, then paste it into any app with one tap. PASTE FROM THE KEYBOARD • Your notes in every app: Use your saved notes, quick replies and templates in Messages, WhatsApp, Gmail and any other app, filtered by tag, pinned or recent. • Paste key: Insert what you copied without switching keyboards. It needs Allow Full Access and reads the clipboard only when you tap it. • Smart placeholders: {date}, {time}, {date+3}, {clipboard} (keyboard: with Allow Full Access) and {cursor} fill in as you insert; Insert Placeholder in the editor adds them. • Switch back after inserting: Go back to your other keyboard right after a note goes in. • Keyboard tabs: Notes, Keyboard, Draw and Kaomoji. The Keyboard tab is plain typing (letters, 123, VN), no autocorrect or suggestions; Kaomoji inserts by category, plus Recent. Both work while MemoKey is locked and without Full Access; nothing you type is stored. • Fill-in fields: {ask:Name} asks for a value as you insert; the keyboard shows your last 5 answers as chips, on this device only and never for locked notes (off or Clear in Settings > Keyboard). • Telex: The VN key types Vietnamese in the Keyboard tab and fill-in fields (Vieejt becomes Việt); touch and hold a letter to type it as is. ORGANIZE IN SECONDS • Tags, pins and search: List or grid view, pin the important notes, drag pinned notes into your own order and find them in seconds. • Tag filters: Tap a tag on a note card to see its notes, or a second tag in search for notes with both. A new note added there gets those tags. • Find and Replace: Change a phone number, price or link in every note at once or only in one tag, with Undo. • Insert Note: Put another note's text at the cursor while you edit. • Copy button: Copy the note from the editor with placeholders filled in. • Previous Versions: Restore one of a note's last 10 texts; kept on this phone only. • Trash with Undo: Undo after you delete. Deleted notes wait 30 days; swipe a row to restore or delete. WIDGETS AND SHORTCUTS • Home Screen widget: Your pinned notes, or the notes of one tag. On iOS 17 or later a tap copies a note. Locked notes are never shown. • Lock Screen and Control Center: New note, Search notes and Copy note in one tap, also from the Action button (iOS 18 or later). • Shortcuts app: Use a note's text in any shortcut, save text as a new note, or add text to a note with Append to MemoKey Note (iPhone and iPad). • Save from anywhere: Select text in any app and share it to MemoKey to save it instantly. PRIVATE AND OFFLINE • No account, no ads, no tracking and no MemoKey servers. MemoKey collects no data, and your notes stay on your device. • Protect the app with a passcode, Face ID or Touch ID, and change your passcode any time. • Lock single notes behind your passcode (PRO). YOUR DATA, YOUR WAY • Backup to iCloud or Files: Back up to your own iCloud or a folder in Files (Google Drive, Dropbox), automatically if you like, with a reminder after 30 days. Nothing is uploaded unless you turn it on. • Export: JSON and CSV backups, or all notes in one Markdown file that MemoKey can restore. • Bring your notes along: Import Google Keep (.json), Evernote (.enex), .txt and .md files, Mac Text Replacements and the Gboard dictionary. • Open with MemoKey: Tap a MemoKey backup or export in Files, Mail, Google Drive or Downloads to restore or import it. MORE BUILT IN • 60,000+ kaomoji: A huge library of text emoticons (^_^) by category, searchable in English and Vietnamese. • Scan text: Add the printed text of up to 10 photos at once to a note. Read on your phone; the photos are not kept. MAKE IT YOURS (PRO) Unlimited tags (free: 10), locked notes, custom colors and your own background image. What you set up with Pro stays yours if Pro ends. --- Terms of Use: https://www.apple.com/legal/internet-services/itunes/dev/stdeula/
