Logseq Mobile App Slow and Laggy
Ongoing iOS, Android Updated October 21, 2026
Quick answer
The Logseq iOS and Android apps are widely reported as slow with large graphs: long loading, laggy input and endless 'parsing files'. Clearing the cache, trimming huge pages and keeping the graph small on mobile help; many users fall back to another app for capture.
Most likely fix: Clear the app cache.
Symptoms
App takes a long time to open, keyboard input lags, stuck on 'parsing files', battery drain.
Why it happens
- Large graph parsed on every launch
- Very long pages
- Corrupted app cache
- Graph syncing through iCloud while it loads
How to fix it
Try these in order — the most common fix is first.
1. Clear the app cache
- iOS: delete and reinstall Logseq (your iCloud files stay)
- Android: Settings > Apps > Logseq > Storage > Clear cache
- Reopen and let the graph re-parse fully
2. Split huge pages
- On desktop, break very long pages and journals into smaller linked pages
- Let them sync to the phone
3. Let the first parse finish
- Keep the app open on Wi-Fi and charging until parsing completes
- Avoid editing during the first load
4. Update the app
- Install the latest version from the App Store or Google Play
- The 2026 DB version includes mobile UX upgrades
