What’s New Version 1.5.0
• Import GPX files. Bring routes, workouts, and old exports into your timeline: open a GPX file from the Files app or a share sheet, or use the new Import GPX File option on the timeline view. You can adjust dates and timezones before importing, existing timeline data is safely set aside when an import overlaps it, and any import can be removed again later with everything restored exactly as it was. (BIG-204)
• Background recording without the persistent location indicator. Arc no longer keeps the location indicator lit while recording in the background. (BIG-617)
• Further improvements to recording on underground trains and metros, plus a fix for out-of-order location data that could distort recorded paths. (BIG-607)
• New Export Diagnostics option on the timeline view. If a day ever looks wrong, it packages everything we need to investigate into a single file you can send us. (BIG-626)
• Arc's documents folder is now visible in the Files app (On My iPhone, Arc Timeline 4).

Build 887419247v1.4.02026-06-25 23:31:24

Build 887217091v1.3.32026-06-20 22:41:15
• Fixed a UI freeze that could occur after returning to the app. (BIG-595)
• Improved the reliability of migrating your data from the original Arc Timeline app. (BIG-598, BIG-608, BIG-611)
Build 887017286v1.3.22026-06-16 23:57:36
• Fixed a case where backups on storage-constrained devices could restart from scratch instead of updating incrementally. (BIG-597)
• Fixed a rare case where recording could stop after an app update. (BIG-604)

Build 886567646v1.3.02026-06-06 01:45:19
• Ask about your timeline in plain language. The search field now understands natural-language questions, and a new chat view answers back in plain prose and handles follow-ups. It's opt-in, and an early foundation we'll keep building on.
• Search now includes your saved places, alongside visits, trips, and notes.
• Better recording underground. In metros, subways, and tunnels where the phone loses GPS, Arc now recognises the situation and does a better job of following your actual route instead of stalling at the station entrance.

• New Storage view in Settings — see how much space Arc Timeline 4 is using on device and in iCloud Drive, broken down by category (BIG-313)

• Fixed the share button on the daily timeline staying visible when navigating into timeline sub-views
