OneLine
Minimalist notes for your Home and Lock Screen
OneLine is a minimalist note-taking app that lets you display your notes directly on your iPhone's Home Screen and Lock Screen using widgets. Write quick notes with rich text formatting, attach images, and tag notes to places so the right one appears when you tap a widget — all kept private on your device.

Frequently Asked Questions
How do I add a widget to my Home Screen?
Long-press on your Home Screen, tap the + button in the top corner, search for "OneLine", select your preferred widget size, and tap "Add Widget". You can then long-press the widget and choose "Edit Widget" to select which note to display.
How do I add a widget to my Lock Screen?
Long-press on your Lock Screen, tap "Customize", select your Lock Screen, and tap the widget area. Search for "OneLine" and add it. The Lock Screen widget always shows your pinned note.
What is the pinned note?
The pinned note is the one displayed on Lock Screen widgets. You can pin any note by opening it and tapping the pin icon in the toolbar. Only one note can be pinned at a time.
Can I attach images to my notes?
Yes. Open a note and use the attachment button to add photos from your library or paste an image from the clipboard. OneLine automatically detects QR codes and keeps them at full quality so they stay scannable. Images appear in the app only — not on widgets — and are stored privately on your device.
How do location-aware notes work?
You can tag a note to a place. When you tap a OneLine widget, the app checks your current location and opens the note you saved for wherever you are — handy for door codes, parking spots, or gate instructions. This feature is optional and requires location permission. If location is unavailable or you decline access, the widget simply opens your default note. Your location is only checked at the moment you tap, and never leaves your device.
How do I find a specific note?
Create as many notes as you like. The main list includes a search bar — just start typing to filter your notes instantly by their contents.
Why isn't my widget updating?
Widgets update automatically when you edit notes in the app. If a widget seems stuck, try opening the app and making a small edit to the note, or restart your device.
Can I sync notes between devices?
OneLine currently stores notes locally on your device. Cloud sync is not available at this time.
