Improved reliability of subscription restore. A new "Get help" button now appears if Restore Purchases doesn't surface your existing access — taps to send diagnostic info to support so we can sort it out.

All new subscriptions and Lifetime purchases now happen in Arc Timeline 4. This app stays in place for existing subscribers. The subscription view is now clearer, with a more prominent Restore Purchases button and a quick link to Arc Timeline 4 if your access needs syncing.

Arc Timeline 4 is now available on the App Store - a ground-up rebuild with higher quality recording, proper dark mode, a new Places tab, and more. Your subscription carries over automatically.

- Added a new Privacy Setting for including Shared Photo Libraries in timeline view - Hopefully finally fixed the airplane segment merge fails - Fixed some setting changes not saving in some cases

## New timeline confirmation flow - The "needs confirm" flow has been redesigned and rebuilt, and now includes both "uncertain" items and "unconfirmed" items - Uncertain items are the same before - items where the app isn't sure about its choice - Unconfirmed items are all the rest - items that the app feels confident about, but that you haven't confirmed - A new "Confirm All" button allows for quick confirmation of these, locking in the of these, locking in the timeline's state as it appears at that time ## Other bits - Added rowing to the activity types that can be saved to Apple Workouts - Photos from shared libraries are now filtered out - Many bug fixes, performance improvements, and minor tweaks. It's been a while since the last update so there's been an accumulation of cleanups and fixes since then!

- Prep for the upcoming companion app, Arc Timeline Recorder - A bunch of crash fixes

## GPX importing is now supported! Tap the ellipsis/more menu on Timeline view to find the GPX importer. Imported data can then be edited the same as existing Arc data. ## Other - Can now mark entire timeline items as bogus, from the more menu on Confirm/Edit view - Misc energy use improvements for better battery life

- Fixed photo thumbnails sometimes incorrectly appearing at top of details views - Fixed weather rows sometimes disappearing from item details view - Fixed a crash

- Hopefully fixed the problem of the classifier favouring unlikely activity types in new areas - Fixed a bug that was causing some JSON exports to be missing sample and place data

- The new status bar / Dynamic Island indicator setting is now shared with Arc Mini

- Arc App no longer depends on any server-provided activity type models! This means both greater energy efficiency, and more accurate activity type detection. Thanks to Astra for making this happen in LocoKit :D - Rebuilt timeline view navigation and menus, to use more modern code and iOS standard menu styles - Added a new setting to Settings tab -> Privacy Settings, for turning on the status bar / Dynamic Island location use indicator. See the explanation in the app for how this might improve energy efficiency. It's defaulting to off for now, because everyone hates that location use indicator - Made some other minor energy efficiency improvements - Fixed some random crashes

- Fixed a crash on Confirm/Edit view

- Added the much wanted "Extract Brief Visits" feature! Accessible from the more/ellipsis menu on trip item details view and edit view - When assigning a place to individual segments you can now choose to set a one-time custom title (again, in the more/ellipsis menu) - Places results list now uses Mapbox's database by default, with the option to search Google Places as a fallback

- More improvements to Google Places searching - Improvements to the Low Power Mode UI

- More tweaking to the handling of Google Places results

- Various cleanup bit to complete the transition from Foursquare to Google Places

- Rebuilt and standardised the Confirm/Edit view header - Replaced Foursquare with Google Places

- In Confirm/Edit view, places that overlap the visit are now grouped at the top - Added little grey dots to items on timeline view that need confirm - Added "Confirm place" and "Confirm [activity]" to long-press menus on timeline view - The "Clean up" button for visits now also marks samples outside of the radius as 'bogus' - Fixed the bug where timeline view would jump a day off when navigating from calendar view - Added “clean up segments” and "Edit segments" buttons to the more/ellipsis meun on Item Details view

- Added hiking activity type - Allow saving of hiking, surfing, and swimming items to Health app - Renamed "Convert moving segments to stationary" to "Clean up", and added a similar feature for path items - "Clean up" for visit items now more aggressively cleans up when it's the first or second visit to a new place - The Place Merge view now indicates which places in a potential merge are Foursquare places - Hooked up place icons for a bunch of Foursquare place categories

Fixed a crash on Visit Edit view.

## New - Moved Place Details to a new separate Place view - Added a "Merge places" feature to the new Place view - Added a "Convert moving to stationary" feature to Individual Segments view - Added surfing activity type, and ability to import surfing workout routes ## Fixes and Improvements - Improved header layouts and scroll behaviours on some views - improved workout-route matching logic when importing workout routes - Fixed imported workout route items not fetching some Health app data - Fetch hourly weather data for timeline items as short as 10 minutes - Immediate Place details updating if Place has few visits - Correctly import swimming workout routes

- Finally added photos to the Overview tab! - Weather reports are now fetched for timeline items as short as 20 minutes

## Added hourly weather reports Each timeline item now shows hourly weather reports on its item details view. These reports are provided by Apple's WeatherKit service, which provides both current and historical weather data. This means you can look back through your timeline data and find out what the weather conditions were in the past (so long as the timeline item's date is after the launch of Apple's WeatherKit service, mid last year). ## Migrated to latest Mapbox SDK This one is largely just a housekeeping task. Mapbox completely rebuilt their maps SDK a couple of years ago, and are now requiring everyone to migrate to the new version. This doesn't add any new maps features in Arc App, but it did take up a hefty chunk of development time, and as such represents the bulk of the changes in this update. You might notice some small changes in the appearance of the maps, but otherwise they should continue to function the same as before.

Fixed the problem of the app getting suspended in the background on iOS 16.4.

## Fully rebuilt all the charts on timeline item details views - Heart rate chart is now colour coded by heart rate zones - Speed and altitude charts show both points and line, to communicate the data noise versus the trend over time - Histogram views for common speeds, visit durations, and visit arrival and leaving times are now displayed as horizontal bars, to better accommodate histograms with many bars ## Other bits - Cleaned up the "Sleeps" section on item details view, with it now showing totals per sleep category (eg in bed, deep sleep, etc) - Fixed the annoying bug that would kick you back to the timeline view while trying to do cleanup edits in the Individual Segments view - Fixed Activity tab summaries incorrectly including duration and distance amounts from "bogus" items - Fixed the calendar view not respecting the system setting for first day of week - Significantly reduced the amount of nonsense moving type segments inside visits
