Think you can fight? Prove it in 30 seconds. ChinCheck is the AI fight judge for shadowboxing. Step in front of your phone, throw hands, and get a 0-100 verdict: your score, tier, roast, six-score breakdown, and what cost you points. No gloves. No bag. No gym. Just you, your camera, and the number your friends have to beat. THE VERDICT Every round is scored across power, speed, defense, technique, head movement, and footwork. ChinCheck turns those reads into one fight score you can defend. THE ROAST The Judge does not hand out participation trophies. Every verdict comes with a one-line roast built for the group chat. Post the card, send the challenge, or run it back until the number looks right. BEAT YOUR FRIENDS Send a score-to-beat challenge straight from your verdict. Friends step in, record their own round, and try to take your spot. The number settles the argument. NOWHERE TO HIDE Six dimensions. One verdict. See what carried you, what exposed you, and how close you are to the next tier. SEE WHERE YOU RANK Weekly rankings give everyone a fresh card. Camera fights only, so the board stays fair. Chase the next score and defend your record. BUILD YOUR CREW Create a crew, invite friends, and climb together. Your crew score is built from your strongest fighters for the week, so everyone has to throw hands. FIX WHAT COST YOU ChinCheck names your biggest leak and points you toward drills for power, defense, speed, technique, head movement, and footwork. Pro unlocks unlimited run-backs and the full Judge's Read. WHAT YOU GET 30-second camera fight scoring 0-100 AI fight score Six-dimension breakdown Tier, roast, and share card Friend challenges Weekly rankings Crews Streaks, trophies, and daily challenges Training drills for your weakest spots Pro: unlimited run-backs and the full read ChinCheck is for entertainment and training feedback.
