Make Obsidian Sync work in background (on Mobile)

+1 as well :slight_smile:

To avoid iOS-caused sync conflicts, Obsidian only needs to be able to sync the last 2 seconds of text edits after having been backgrounded.
Currently it stops syncing the moment you exit the app.
I wish the devs could investigate if that can be done.

Obsidian needing to download the latest syncs after opening is less of an issue imho.

+1 for the permanently visible sync status indicator on iOS


OMG, I just noticed the “Prevent device sleep” setting on mobile: “Prevents the device from going to sleep when there are still files to be synced.” !!!

I don’t see it announced in the forum or documented in Help. I have no idea how long it’s been there, but I’ve enabled the heck out of it now.

EDIT: Hmm, maybe this only works when Obsidian is in the foreground? I’m hoping it at least requests the little extra time that iOS apps can request to finish things when they are closed. I’ll leave it on and see how it goes.


I don’t see the background refresh setting at all in the system preferences panel (ipad os). I think we could get more from it.

I think maybe the setting has helped somewhat, but it’s hard to tell (and it’s taken time to unlearn the waiting habits I developed to compensate for how Sync works on iOS). But Sync still occasionally suffers from red icon, and/or doesn’t sync if I close too fast. I feel like it’s less of a problem than it used to be, but also that improvements started before I turned on the setting. So, :woman_shrugging:t2:

it’s in settings/sync, “prevent device sleep”. That’s the only setting

+1 on this! :smiley:

Its annoying that this does not already work. Makes obsidian impossible to use on mobile

Does Obsidian ios retain the entire vault in memory? I wonder if maintaining smaller vaults would reduce the frequency of ios kills


I believe this is the single most important feature for Obsidian Sync users.
I migrated to Obsidian Sync from a private Syncthing setup, and while the sync itself works really well, the fact that when I open Obsidian on mobile, after an already too-long startup time I need to wait for a full sync before it’s fully usable, is a huge pain.
A simple common flow like logging something in the daily note becomes extremely cumbersome, sometimes requiring more than a minute before I can type the single line that I wanted to log. Not to mention things like completing tasks etc from mobile.


Here is a little ‘hack’ to keep Obsidian backgrounded on iOS, which even enables background sync while your iPhone is unlocked. I still need to take the time to write this up and post it on the forum:

The idea in short:

  • take a short video (f.ex. a 1 sec screen recording), place it in your vault, play it, put it in picture in picture mode, and slide it off screen. It will stay there even if you watch other videos in between.
    On my iPhone 11, it remains active for many hours or all day.

  • alternative: create a some hours long empty mp3 file, add to vault, play it. That note needs to remain open, so pin it. Downside: when you play other sounds, it stops and Obsidian won’t be backgrounded anymore.

Let me know if you run into any issues!


When at home I use mainly Obsidian in my PC but on the go I use Obsidian in my Galaxy Tab. And specially when I’ve edited many files, it takes so long to update that it’s absolutely annoying.

Another solution would be to improve speed of Obsidian Sync, which is known to be slow.

I don’t understand why my phone can download 1gb of podcasts in the background & refresh my rss feeds and obisidian can’t be opened without first syncing with iCloud.


Because iCloud “intelligently” decides to remove data from your phone so you have space for other stuff. So we need to check that your notes and config are still there and if not redownload them.

Also this has nothing todo with this thread.


I’m with you. Love Obsidian and my markdown note system, but the lack of attention to the fundamental UX for mobile use is incredibly frustrating. I’ve been waiting for them to make a proper feature to disable certain plugins on mobile that doesn’t require janky config file editing (Save settings for which plugins are enabled for mobile and desktop separately - #2 by rflmorais)

Having to always wait to make sure files are synced before editing, and waiting afterwards to make sure they sync before you close the app, just makes me never open the app on mobile at all unless absolutely necessary.

I’m still trying to figure out a task system that works fine for me, and Obsidian is absolutely ruled out because of this issue; I often want to quickly add tasks from my phone, so I resign to Google Tasks for now :confused:

I strongly agree on this. When Obsidian Mobile was released I thought I would be using it whenever I have some time to do it (waiting for something or someone in the car, waiting in a queue, etc.), but it’s just not useful because of how Sync works.


I’m aware of this, but I paid for Obsidian Sync for a reason. It is seamlessly integrated, works well, and has version history.

“Set up and use a completely different sync system” certainly does not address or excuse the poor UX at hand, and sync is only half of the problem of mobile usability.

I know it might be difficult to set up Sync to work in background, but what about increasing the speed of syncing? I think there should be a way to make the process work faster…

Apologies if this was mentioned already, but I’m surprised Obsidian Sync isn’t requesting to use iOS native “Background App Refresh” access to accomplish this. See for example that Obsidian doesn’t request this:

Whereas similar apps like Evernote do:

This isn’t bulletproof (iOS still algorithmically allows background access based on how often the app is used, battery impact and various other factors) but it’s the “right” way to do it on iOS.

I can’t speak to Android but I believe it offers similar APIs.

I’m not sure what underlying development platform obsidian is using but React Native offers this with APIs like react-native-background-fetch (react-native-background-fetch - npm) to do this.

Evernote is also a cross-platform mobile app, I believe written in React Native.

So I believe iOS offers some opportunity for this to be implemented for Obsidian Sync in a “native” way. This would apply to iCloud Drive sync which, as mentioned, handles background already at the iOS level.
