OwnDay is a private, on-device diary of your day. It quietly notices where you go and what you do, then turns that into a clear timeline and useful insights about your time—all while keeping your archive on your iPhone. WHERE YOU’VE BEEN OwnDay uses Apple’s location services to recognise visits to places you go. Save a place or correct it once—its name, role, or the activity you were doing there—and OwnDay remembers it for next time. WHAT YOU’VE BEEN DOING Connect Apple Health and Motion & Fitness to bring in sleep, Apple Watch workouts, walking, running, cycling, and other activity signals. OwnDay blends this with your visits into a single timeline, so a day at the gym, an evening walk, and a night’s sleep can appear alongside where you were. YOUR DAY, AT A GLANCE Timeline shows your day as a sequence of visits, journeys, and activities. Each entry can be edited. Insights breaks down your time by activity across a day, week, month, or year, helping you notice patterns over time. PRIVATE BY DESIGN Your visits, places, notes, timeline, Health data, and activity records stay in local storage on your device, protected by iOS data protection. OwnDay has no account, advertising, analytics, or cloud sync, and does not send your archive or Health data to a developer-operated server. When OwnDay needs to identify a nearby place, it may use Apple Maps. That lookup is handled under Apple’s own privacy terms. You can back up and restore your archive on your own terms. BUILT FOR REAL DAYS Location tracking is designed to be low-power. OwnDay watches for visits and significant location changes rather than continuously tracking GPS, helping it work in the background without unnecessary battery use. OwnDay is for anyone who wants a quiet, private record of their own life—without handing their personal archive to a server.

Verdict
The clearest difference is update cadence: OwnDay at every 4 days against REON POCKET's every 2 months. REON POCKET's advantage is device support (3 vs 1) and iOS requirement (15.0 vs 26.0). On price, ads and in-app purchases there is nothing between them.
