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, and calendar snapshots — is stored only in your own iCloud, syncing quietly across iPhone, iPad, and Mac through your Apple ID. No account to create, no Google or third-party sign-in, no ads, no tracking. ■ 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, and pick a daily cover to represent each day - Organize life with moods and tags; filter and revisit anytime - Auto-record where you were and the weather as you write (optional) - 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) ■ Look back, gently - Media calendar: browse a whole month as photo thumbnails and switch freely between List and Calendar, like an album - "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 third-party analytics SDKs - 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. Inkday Pro unlocks extra themes, location & weather, calendar snapshots, statistics, the footprint map, and export backups — available as a yearly plan, a monthly plan, or a one-time Lifetime purchase. Tired of renewing every year? Inkday lets you buy it once. Every day of yours deserves to be kept well.

Verdict
The clearest difference is in-app purchases: Relation Log at none against Inkday's 3. Relation Log also leads on iOS requirement (13.0 vs 17.0). Inkday's advantage is update cadence (every 9 days vs every 3 weeks). On price, ads and device support there is nothing between them.
