Hey Hunters 👋 I'm Chosk, an indie iOS dev from Seoul. One Line is the note app I kept wanting: one input box, and whatever you write goes where it belongs. What it does - Write "dentist tomorrow 3pm" → calendar event. "call mom" → to-do. Anything else → note. - Three screens: Today (what's due and scheduled), Notes (everything without a date), Calendar (everything with one). - Wrong guess? One tap moves it. No folders, no tag syntax, no rules to memorize. Capture without opening the app - Home and lock screen widgets - Share sheet — send a link, a page or a photo from any app straight into a line - Reminders, dictation, and text pulled out of screenshots - Korean and English both parse How it decides A dictionary and a date calculation, not an AI. That means it's instant, it's the same answer every time, and it works with the phone in airplane mode. Until you turn sync on, nothing leaves the device — no analytics SDKs, no ads. Pricing Free for notes, to-dos, events, editing and sync. Pro (in-app) adds cloud storage for attachments, screenshot text extraction and dictation. There's a web version at oneline.date if you want to try it before installing, but the iPhone app is where it's meant to live. I'd love feedback on the classifier — especially where it guesses wrong on your phrasing. Reply with the line and I'll fix it 🙏
