​
Progress Synchronization

Your progress syncs across devices in real-time:

​
How Sync Works

  1. Watch on Device A: Start watching on your computer
  2. Auto-Save: Progress saved to cloud database
  3. Switch to Device B: Open AniDev on your phone
  4. Resume: Continue from exact same position

​
Sync Frequency

  • During Playback: Every 30 seconds
  • On Pause: Immediately
  • On Episode Complete: Immediately
  • On Page Close: Before you navigate away
Sync requires an active internet connection. Offline changes will sync when you reconnect.

​
Managing Your Progress

​
Reset Progress

You can reset progress for any anime:
  1. Navigate to the anime detail page
  2. Click on progress settings
  3. Select “Reset Progress”
  4. Confirm the action

  1. Go to the episode list
  2. Right-click (or long-press) an episode
  3. Select “Mark as Watched”

  • Mark all as watched: Useful for anime you’ve seen before
  • Mark all as unwatched: Reset entire series
  • Mark up to episode X: Mark all episodes up to a specific one
Bulk actions are available in the episode list settings menu (three dots icon).
