☁️ My progress isn't syncing between my iPhone and iPad ▼

ETPattern uses iCloud/CloudKit to keep your data in sync. If you're experiencing issues:

  • Check iCloud: Ensure you are signed in with the same Apple ID on both devices.
  • Enable iCloud Drive: Go to iOS Settings > [Your Name] > iCloud > iCloud Drive and ensure it's enabled.
  • Internet Connection: Syncing requires an active internet connection.
  • Wait for Sync: Initial sync may take a few moments.
  • Force Refresh: Pull down to refresh in the app's main screen.
🔊 I can't hear the audio/Text-to-Speech ▼
  • Silent Mode: Check if your device's physical silent switch is on. Flip it to the unmuted position.
  • In-App Settings: Open the app Settings and ensure the Volume slider is turned up.
  • Voice Selection: Try selecting a different voice in the Settings menu if the current one isn't working.
  • Device Volume: Use the side volume buttons to increase overall device volume.
  • Speaker Check: Play audio from another app to verify your device speakers work.
📊 What do the different "Maturity" levels mean? ▼

In the Mastery Dashboard, we categorize cards based on how well you know them:

  • New: Cards you haven't studied yet. These are ready for your first review.
  • Learning: Cards you are currently studying but haven't fully memorized. Review them regularly.
  • Mature: Cards you have correctly recalled consistently over a long period. These need less frequent review.

The app uses the FSRS (Free Spaced Repetition Scheduler) algorithm to optimize your review schedule automatically.

ETPattern provides comprehensive progress tracking:

  • Daily Streak: Track how many consecutive days you've studied.
