🏐 AI Hit Analysis
Trim your clip to a single spike and let the analyzer return velocity, power, contact height, and spin — calibrated for indoor and beach volleyball.
📈 Hit History & Trends
Every measured hit is saved to your history with date, court, and conditions — so you can see how your numbers move week over week.
🏆 Friends, Team & Global Leaderboards
Add friends with a share link, create or join a team with a code, and chase the top of the global board for the hardest hit of the week.
🎞️ Slow-Mo Replay & Overlays
Scrub frame-by-frame with stat overlays burned in. Great for breaking down approach, contact, and follow-through.
📲 One-Tap Share
Export clips with the stat overlay locked on — drop them straight into Instagram, TikTok, or your team chat without a separate editor.
🔒 Local-First Recording
Videos stay on your device unless you choose to share. Only the analysis payload is sent for processing, and you can delete your data anytime.
