Haru Danim — a visit to your day A habit and time tracker: log time and counts with a single tap, and shape your day with goals and quests. ■ How it works • Create an "action" and tap once — time tracking (start/stop toggle) or count logging (+1), recorded instantly • Track several actions at the same time; while tracking, see it live in the Dynamic Island and on the Lock Screen • Organize actions with color-coded tags, find any action by name, and automatically ignore accidental short sessions and double-tapped counts ■ Goals & quests • Under a big "goal", create actionable "quests" — daily, weekly, monthly, or a custom period • Fine-grained rules: every day / specific weekdays or dates / reach-at-least or stay-under / count only until a daily deadline • Daily, weekly and monthly progress plus streaks and your best streak so far; goals are judged automatically when their end date passes • Set your own achievement threshold from 10–100% ■ History & stats • A daily list and a 24-hour timetable (day/week) show your records at a glance — simultaneous sessions sit side by side, and Apple Health water intake appears as dots at the time you drank • Charts by tag and by action (daily/weekly/monthly) with totals and averages • When charts feel empty early in a week or month, switch to a rolling last-7/30-days view • Export exactly what you see as a high-resolution image report • Back up all data to CSV files (free plan included) — Premium adds CSV import to restore records • Clear out long-accumulated records with Data Cleanup & Reset — with a CSV backup and a keepsake summary report before anything is deleted • See today's Apple Health data (steps, exercise, sleep and more) as tiles on the Home tab, and workout time by type in the Stats tab — values never leave your device ■ Go further with Premium • Unlimited actions, goals and quests • Home Screen & Lock Screen widgets — run and stop right from the widget, progress rings and charts • Really Big Widget — design a full-page widget block by block — actions, goals, a calendar (events + records), a 24-hour day grid, photos and more; date and text blocks come with fonts like serif and handwriting (iPhone on iOS 27 and later, iPad in landscape; building presets is free) • Launch from Control Center and the Action button • Apple Watch app and complications — track from your wrist, with an Action Log complication showing totals on your watch face • Siri Shortcuts — "Hey Siri, start tracking Reading in Haru Danim" • iCloud sync across iPhone, iPad and Mac • Diary on iPhone, iPad and Mac — a daily summary page plus free-form notes (Apple Pencil on iPad, finger drawing on iPhone, mouse and keyboard on Mac), with your own PDF page templates. The summary now includes a health-data card and a timetable with your sleep and workouts laid in • CSV import — bring actions and records back from your exported CSVs • Health quests — goals from Apple Health data like steps, sleep and workout types ("8,000 steps a day," "8 hours of sleep") ■ Privacy This app collects no personal data. Everything stays on your device and (if you turn on sync) in your own iCloud.

About

One Line

Type one line. That's the whole system. Most notes apps die the same way: organizing them becomes the work. Folders, projects, boards, tag syntax — a filing system you have to maintain before you're allowed to write anything down. One Line has none of that. You type a line and it files itself — "buy milk" becomes a to-do, "dentist tomorrow at 3pm" becomes an event with a reminder, and everything else stays a note. If it reads a line wrong, one tap changes it, and it remembers the correction. ■ Notes, tasks, and events in one stream Not three apps. Not three tabs you keep forgetting to open. One place you actually write to, with a Today view for what's in front of you and a calendar for what's coming. ■ Nothing leaves your device unless you ask No account is needed to use the app. Your writing is stored on your iPhone, and the app reads and sorts it on the device itself — nothing is sent anywhere to be processed. No ads, no tracking, no advertising identifier. Airplane mode changes nothing. Turn on Cloud sync and you sign in with Apple or Google; only then is anything you write stored on our servers. The separate, opt-in usage stats send counts of which features you used, once a week, plus a crash report if the app quits on you — never your notes. Turn on link previews and the request goes straight to that site — never through us, and we never learn what you looked at. It is off until you turn it on. ■ You don't have to open the app · A Home Screen widget shows today at a glance · Tap the widget once to capture straight into the app · Share from Safari and the page title and article are saved with it — add "todo read tomorrow" while sharing and it becomes a task for tomorrow · Share text or a screenshot from any other app and it's saved · Due dates and events arrive as notifications ■ Gets in without typing (Pro) · Share a screenshot and the text on it becomes a note — menus and status bars stripped, dates, phone numbers and amounts pinned to the top · Snap a photo or a document and the text inside is read · Record a voice memo and it is transcribed · Long articles shared from Safari can be summarized in a few lines (Apple Intelligence devices) · The reading happens on this device. Photos and voice are never sent anywhere to be read ■ Free, and actually complete · Unlimited notes, tasks, and events · Natural-language dates in English and Korean — "dentist tomorrow 3pm", "report by friday", "every monday gym" · Sync across your devices — sign in and pick up where you left off. Photos, recordings and attachments come along too, up to 5 GB · Today view, calendar, notifications, widgets · Export a backup file and restore from it · Export everything as Markdown files No item caps. No ads. No trial that runs out. ■ One Line Pro · Yearly, with a discounted first year · Monthly · Lifetime — a launch price. Pay once and keep every Pro feature, including the ones that come later · Gets in without typing — Text from photos · Transcription · Article summary (Apple Intelligence devices) · Search what piled up — Semantic search: find "that hospital thing last month" without remembering the exact words · Keep it on your Home Screen — Pinned note widget Prices are shown in your local currency on the App Store. Cancel any time. Everything stays on your device. ■ Terms & Privacy · Subscriptions renew automatically unless cancelled at least 24 hours before the end of the current period. Manage or cancel any time in your App Store account settings. Lifetime is a one-time, non-consuming purchase and does not renew. · Terms of Use (EULA): https://www.apple.com/legal/internet-services/itunes/dev/stdeula/ · Privacy Policy: https://oneline.date/en/privacy
