有些摩擦,不一定真的吵開, 卻會在關係裡反覆出現。 這個 App 讓你記下關係中的摩擦, 不是為了評分對錯,是為了看見模式。 當時間拉長,你可以回顧: • 摩擦發生的日期 • 彼此間隔了多久 • 是否出現重複的情境 • 節奏是加快、放慢,還是維持不變 有時候,問題沒有消失, 但間隔正在變長。 那可能代表慢慢理解、情緒沉澱, 也可能只是暫時壓抑。 功能特色: • 快速新增摩擦紀錄(日期、情境、感受) • 以時間序回顧過往紀錄 • 觀察摩擦發生的間隔與變化 • 所有資料僅儲存在本機裝置 只是讓你看見: 關係,其實是有節奏的。

Inkday is a private journal that's yours alone. We believe something simple: your journal is yours. Inkday runs no servers and cannot see your content. Everything — your writing, photos, videos, audio, moods, tags, location, weather, calendar snapshots, and anniversaries — is stored only in your own iCloud, syncing quietly across iPhone, iPad, and Mac through your Apple ID (activity data is the exception: it stays only on the device that captured it, and isn't synced through iCloud). No account to create, no third-party sign-in, no ads, no cross-app tracking (only anonymous device and OS-version statistics and crash reports, to improve stability). ■ Capture every day - One clean, text-first entry a day, at a glance on the calendar - Add photos, short clips, and voice notes to any entry - Tap any photo or video for a full-screen view, swipe through the day's media, pick a daily cover, or save media back to Photos or a file - Organize life with moods and tags; filter and revisit anytime - Auto-record where you were and the weather as you write (optional); search a landmark or nearby place to set where the day happened - Snapshot that day's calendar events into the entry, so you can look back even after switching calendars or phones (choose which calendars to include) - On iPhone and iPad, automatically save that day's activity from Health into the entry: active energy is free, while Inkday Pro also records steps, exercise minutes, and full workouts (type, duration, distance, pace, heart rate, and more). This stays only on the device where it was captured, not synced with the entry (can be turned off anytime) ■ Remember the days that matter - Anniversaries: record the day you got together, a birthday, or a day to count down to; Inkday works out the years, months, and days that have passed (or just the total days), or how many days remain - Reminders on day 100, 500, 1000 and every anniversary; that day is also marked in your diary, calendar, and list, and one tap adds the sentence to your entry - (iPhone, iPad, Apple Watch) Lock Screen, Home Screen, and watch face widgets show how long it's been, or how many days are left, at a glance - Import events straight from your Calendar, or turn a day's event in your diary into an anniversary - Free for up to 3 anniversaries; Inkday Pro removes the limit, adds custom colors and milestone intervals, and lets you look back on each past anniversary with On This Day ■ Look back, gently - Media calendar: browse a whole month as photo thumbnails and switch freely between List and Calendar, like an album; scroll all the way back to any past date to backfill older entries - "On This Day" brings back the same day in years past - See your writing streaks and most-used moods - A footprint map shows the places you've been ■ Built for privacy - Your data lives only in your own iCloud; the developer can't access it - No accounts, no ads, no cross-app tracking (only anonymous stability statistics) - Built-in App Lock: protect the whole app with a PIN and Face ID / Touch ID (free) ■ Your data, portable - Import from other journaling apps to move in easily - Export your entire journal to a file anytime for a full backup ■ Three platforms, one journal - Shared across iPhone, iPad, and Mac; syncs automatically with one Apple ID - Seven warm, papery themes, with dark mode (follow the system, or stay light or dark) The core is free forever, including location tagging and the footprint map. Inkday Pro unlocks extra themes, weather, calendar snapshots, full workout records, statistics, unlimited anniversaries, and export backups — available as a yearly plan, a monthly plan, or a one-time Lifetime purchase. Tired of renewing? Inkday lets you buy it once. Every day of yours deserves to be kept well.
