Trips, projects, workouts, daily expenses — everything finds its place on a timeline. 【Timelines】 Organize scattered records into named timelines: travel, fitness, renovation, parenting, daily spending... Entries group automatically by day, week, or month, so you can see the flow and gaps of your time. 【Diary】 Capture the moment with photos, colored tags, and location. Writing suggestions (iOS 17.2+) pull inspiration from your daily life.

Filter by location (country/city/street), date range, colored tags, and amount range to find any memory fast. 【Flexible Organizing】 Merge timelines into another of the same type. Move a single record to a different timeline.
