Recall Shard

Recall Shard helps learners turn knowledge notes into focused active-recall review sessions. Create reusable shards with a title, category, content, recall question, and tags, then review by trying to remember first and revealing the answer when ready.

The app includes remembered/still-fuzzy feedback, local library organization, category filters, review summaries, and daily reminder controls. Notification permission is used for review reminders. Vibration permission may be used for device feedback where supported.
