Description
OpponentBook is a private journal for individual-sport athletes: log matches, keep notes on everyone you face, and pin tactics directly on the piste, table, court, ring or mat. Each pin links to the exact second in your match video. Your notes live on your own Google Drive, Dropbox or iCloud, not on our servers, so we can't read them. 17 sports and 21 languages, with a generous free tier. Premium, Pro and Max add stats, heatmaps and AI briefs based on your own notes.
