Arc Editor public beta 25

1.0 (build 49), 2026-04-04 15:25 (Bali)

Bug Fixes

  • Improved sleep mode departure detection, reducing missed recording at the start of trips (BIG-381). Sleep mode now extends wakeup checks when GPS data suggests movement, allowing the system to gather more evidence before going back to sleep.
  • Fixed a delay of up to 30 seconds after granting HealthKit permissions during onboarding before advancing to the next page (BIG-199)

Other Changes

  • New app icon, now with dark mode support

The new icon looks, well, interesting in the Tinted view:

(This is dark tinted but the light tinted is kinda similarly low contrast.)

I’m not sure this is actually resolved? I think this morning it missed 40 minutes of recording at the start of my trip. Then after 40 minutes of not recording the debug logs say “[10:44:37.104] [LOCOMOTION] SleepDetector: unfreezing — filtered location outside geofence”. Previously when I was actually stationary the log contained one entry of “[09:36:43.098] [LOCOMOTION] LocomotionManager.startSleeping()” and several entries of “[09:37:55.132] [LOCOMOTION] Extended wakeup started: raw outside geofence, Kalman inside”.

Is it expected to see “Importing timeline data” screen with a progress bar after each update? I don’t recall seeing it in the past often (maybe once or twice), but it shows up every beta update recently. It takes a couple of minutes before it’s dismissed. Probably not an issue. I just want to confirm it’s expected.

@trackerminerfs Could you send me that log file? To matt@bigpaua.com is probably easiest. Thanks!

Definitely not expected!

It doesn’t ask you whether you want to resume first, yeah? It just goes straight into that importing view?

If so, that means it’s the migration view for migrating from the old app. And that should only ever run once to completion. If it gets stopped part way through (eg app terminated) it’ll auto resume on next app restart. But once it finishes that should be the end of it, not resuming again.

So it sounds like for some reason it’s not marking the migration as complete. Hmm. I’ll look into this today! Thanks for the heads up.

@darrarski Found it! The next build will stop doing that. And that will probably arrive in the next 1-3 days I think. No longer than that.

It seems a subscription is required for the test build?

In the old version of Arc, if memory serves, there was an export button which allowed for that days timeline or map to be exported as an image. I used to like this to export my day into DayOne and such.

Is there a plan to add this feature back in?

Some questions / thoughts :slight_smile:

  1. In the calendar view, days with uncertainty used to be in bold which made it easy to go back and confirm the uncertain items. Will this be restored?
  2. I can’t work out how to set a visit to the street address. Is it still possible?
  3. When the timeline view is minimised, I find it unintuitive to restore the timeline by dragging it up. Instinctively, I want to tap the remaining timeline to restore it.
  4. After confirming an item, it returns to the list of unconfirmed / uncertain items but the confirmed item is still there for a short time before sliding away which I find slows the confirmation flow. Personally I’d lose the animation.
  5. Also on the confirmation flow, the confirm button is at the bottom of the screen but I’ve just tapped mid-screen to open the item for confirmation. I know I can tap the top item to confirm but it feels like that’s a shortcut and I should be moving my finger up and down during the flow. I can illustrate if this doesn’t make sense!
  6. When looking at an individual segment, I think the map should zoom in to the segment as it does when nudging the split point backwards or forwards. Segments are often wildly different in scale (metres vs kilometres).

I hope these are useful and make sense!

@extrawdw For the beta builds from TestFlight, purchases aren’t real - no money involved. So you can do a fake lifetime purchase to get through.

Once the app goes live properly on the App Store it’ll be real purchases, but your existing subscription will carry over from the old app. So as long as that’s still active there’ll be nothing new to pay for. The subscriptions and lifetime purchases cover the whole Arc Family of apps.

Definitely! I’ll probably target that one for the next major feature release after v1.0 goes live (hopefully within the next week).

Yep! I’ll at some point be adding a full screen calendar view, specifically for this kind of purpose. The current one is for navigation only, and that iOS native calendar widget doesn’t support annotations, so it can’t be used for this purpose. And it’s too small for that anyway.

I’m hopeful I’ll be able to get this into the next major feature release, so v1.1.

Currently not! I’ll check to make sure I’ve got a task filed for that… Yep, alright filed, targeted at the v1.0.1 release.

That might be because what’s what old Arc Timeline does. But that’s non-standard on iOS. The platform standard is to swipe up and down on content sheets. So Arc Timeline was the odd one out there.

It’s not the animation slowing things down, it’s the processing itself :wink: The list is just updating to show you the current state, as it works through applying the change.

Heh. You’re in disagreement with others who’ve expressed an opinion on this so far. All reports so far are of people happy that action buttons are now down the button, nearest to where their fingers are. Personally I’m in the camp of preferring them down the bottom too.

I’m in agreement on this one. I feel like there might be a reason why it doesn’t zoom in to segments on an edit view for the individual segment. But I can’t think what that might be. I’ll make sure it’s filed to look into it.

Closing the loop here, @Dtwhite — daily timeline as image just shipped today in v1.2.0. Tap the share button on the daily timeline view. Map-as-image is the second part of BIG-387 and is still queued for a later update.

Release notes: Arc Timeline 4 (1.2.0) release notes

— Claude

Thank you for the update, and for taking on board the feedback.
Note - I don’t see an update to the beta Test Flight version of the app. SHould I be just moving to the version in the App Store at this point?

Yes — public TestFlight builds stopped going out when v1.0 went GA on April 17. Updates land on the App Store now, that’s the path forward.

To switch: open the App Store app, search for Arc Timeline 4, tap GET (or Update if iOS recognises the existing install). The App Store version replaces the TestFlight install in place — your data stays put, no backup needed.

Is this still on its way? I notice I can now set a visit to a street address but only if there’s not a known place at the same location. I sometimes want the street address when I stop near to a place but not actually at the place, if that makes sense. Today, I stopped in my car on the street and waited for someone but I can only seem to set that visit to the adjacent place.

@gsoper Yep! Still coming soon-ish. It’s filed for the next feature release update, v1.3. The relevant ticket numbers are BIG-227 and BIG-455.
