Logless is a footprint diary you do not have to write. It drafts the places, photos, steps, and flow of your day on your device. Tidy only what matters, then revisit a day by date or from your own map. ■ Keep the shape of your day without writing With location access enabled, outings and possible stops appear on a simple timeline. Photos and steps add context, so even busy days leave something worth revisiting. ■ Refine only the places that matter Choose a place suggestion, rename a stop, split or merge a visit, or exclude a pass-through point. Confirmed places are learned on your device and gently improve suggestions when you return. ■ Remember familiar routes and travel times Keep routes and durations for trips you make often, such as home to a station, school, or work. Look back on days that took longer than usual or used a different route. When location data is sparse, Logless avoids claiming an exact path and keeps the useful timing instead. ■ Build a map that is yours Revisit saved places and footprints on My Map. Familiar cafes, new neighborhoods, walks, and trips gradually become a personal map of where life happened. ■ Look back by day, week, or month The timeline brings together each day's places, photos, and flow. Weekly and monthly reflections surface familiar places and rhythms without scoring your life. ■ Catch up when you return When you open Logless, it rechecks up to 30 days—today and the previous 29—using available Location and Health evidence on your device. Photo details are added gradually, so not every day is completed at once. “Updates since your last visit” shows past days that were added or changed. “Data Status” distinguishes “Recording · no log yet,” “Recorded,” “Limited evidence,” “Recently checked · no observation,” “Retry needed,” and “Not checked,” plus saved sources and “Automatic activity history.” iOS controls when and how often background work runs. ■ Backup under your control Export Logless records plus location and event history in one portable, unencrypted file; keep it in a trusted location. Logless validates it before restore. Restore replaces current data instead of merging it. Original photos, original HealthKit data, purchases, iOS permission state, UserDefaults, app settings, caches, notifications, and widget state are excluded. ■ Balance accuracy and battery Standard mode uses low-power location signals as its foundation, then briefly improves location detail around signs of movement. Turn on Detailed Route yourself on days when you want a closer path. ■ Privacy, explained clearly Precise movement history, photos, steps, and learned places stay on your device. To show weather, Logless may send a date and an approximate location rounded to about 1.1 km to a weather service. Logless does not use advertising tracking. [Logless is for people who] - Want a journal but cannot keep up with writing - Want to remember where they went last week - Keep memories of walks, cafes, weekends, and trips - Compare commute or school routes and travel times - Prefer looking back through places instead of paragraphs [Logless Pro] Unlock broader monthly, yearly, and city-level reflections and longer-term ways to revisit your history.
