Singlenote is a notes app with a single note. Always open, always at hand, nothing to organize.
Most note apps ask you to manage notebooks, tags, and folders before you can write anything down. Singlenote skips all of that. Open the app and you're straight into your note: the one place for the door code, your Wi-Fi password, a booking reference, your work schedule, or whatever you need to check again and again.
WRITE AND FORMAT
Bold, italic, underline, links, bullet lists, numbered lists, and checklists. Paste in Markdown from anywhere and it formats itself.
ADD IMAGES
Drop in photos of tickets, IDs, receipts, or anything else worth keeping close. Drag to reorder them, tap to view full-screen with pinch-to-zoom.
SHARE IN A TAP
Send your note to WhatsApp, email, or any app, formatting intact. Share text or images into Singlenote from other apps too, straight into your note.
LOCK IT WHEN YOU'RE DONE
Switch to read-only with one tap so nothing gets edited by accident, then unlock to keep writing.
MAKE IT YOURS
Light, dark, or automatic. Three text sizes. Six languages: English, Spanish, French, German, Portuguese, and Italian.
PRIVATE BY DESIGN
Your note stays on your device. We never see it, store it, or back it up on our servers. Singlenote collects a small amount of anonymous usage data to help us improve the app: things like note length or which tools get used, never your note content. Turn it off any time in Settings.
One note. That's the whole app.
Terms of Use: https://singlenote.app/terms-of-use
New: PDFs in your note, with Singlenote Pro.
• Import any PDF: tickets, maps, guides, boarding passes.
• Show every page, or just the first one and page through the rest when you need them.
• Reorder pages, delete them, or write between them.
• Download or copy any page.
Singlenote Pro is an optional monthly or yearly subscription. Everything else in Singlenote stays free.
To make room for PDFs, the underline button has left the toolbar. Text you've already underlined keeps its style.
