About this app

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 or mat.

SIXTEEN SPORTS
Fencing, table tennis, tennis, badminton, squash, padel, judo, karate, kendo, kyokushin, taekwondo, boxing, 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 — 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.

FREE, FOR REAL
• Unlimited opponents, matches and training entries
• Unlimited photos and video clips (they live on your storage)
• Tactical pins on the actual playing surface
• Cross-device sync through your own storage
• PDF and Word export — hand your coach a clean brief
• Works offline; syncs when you're back

GO DEEPER WITH PREMIUM, PRO AND MAX
AI summaries, opponent briefs, match reviews and weakness analysis — grounded in your own notes, in your own language. And one quiet superpower: OpponentBook notices whether you actually reviewed your notes before facing someone, and shows you whether it pays off.

Download OpponentBook and start the journal you keep on every opponent — and on yourself.
