About

OpponentBook

Read full description

Every opponent you've ever faced, remembered. What worked, what didn't, and what to do next time — in a private journal that's yours alone. OpponentBook is a journal for individual-sport athletes. Log matches, keep notes on the people you face, and build a living scouting book over your career — with photos, video clips and tactical pins placed directly on the piste, table, court, ring or mat — and, once you upload the match video, each pin links to the exact second in it: one tap takes you from the note to the footage. SEVENTEEN SPORTS Fencing, table tennis, tennis, badminton, squash, padel, judo, karate, kendo, kyokushin, taekwondo, boxing, kickboxing/Muay Thai, wrestling, BJJ, jujutsu and MMA — each with its own playing surface and vocabulary. YOUR NOTES NEVER TOUCH OUR SERVERS Your journal lives on storage you control — iCloud, Google Drive or Dropbox — never in our database. We cannot read your notes: that's how the app is built, not just a promise. Optional end-to-end encryption hides your entries from your storage provider too.
