Volleyball coach app — rotations, live scoring, AI analysis

VBER (排球人) is a free web app — installable as a PWA — for volleyball coaches and players: manage the roster, simulate rotations, score matches live, track stats, and use AI to analyse games, scout opponents and plan training.

All the core features — roster, rotations, live scoring, stats, training and fitness — are free forever, in any browser on any device, and you can add it to your home screen like an app. Only AI analysis uses credits, and every new team gets 30 free credits to start.

Each AI action spends credits: a live tip is 1, an AI match report or practice plan is 3 each, an AI post-match video review is 6, and opponent scouting is 10. New teams get 30 free; top up when you run out — HK$28 for 40 credits, HK$88 for 150, HK$288 for 600 — and credits never expire.

Pick a pack in the app, pay the QR by FPS (轉數快), and upload the payment screenshot. The AI checks the amount and reference — a clean payment credits instantly, and anything unusual goes to manual review.

Not necessarily. Coaches can add roster players themselves; once a player links a login they can RSVP to training and see their own stats.

Each team's data is isolated and visible only to that team's members. It's locked down row-by-row with Row Level Security (RLS), so other teams or non-members can't access it.

Yes. Coaches and assistants co-edit the roster, matches and stats; players who link an account can RSVP to training themselves, and every change syncs live across devices.

Yes. Score every rally courtside while attributing kills, aces, digs and blocks per player, synced live across devices.

AI finds your weak rotations, gives in-timeout tactical tips, scouts opponents from a YouTube link, reviews your own match video after the game (what you did well and what to improve, per player and overall), and designs practice from who's attending, their positions and recent weaknesses — pulling real drills from the library at a difficulty you pick, with reference clips.

Yes. On the Training page, paste a YouTube drill clip you think is good (it doesn't have to be your own) and submit it for review. Once an operator approves it, AI classifies it into the drill library and your team earns 5 credits.

Get your players to sign up and link their roster profile — each player who links earns your team 10 credits (once per player). They also get to log their own fitness, RSVP and nutrition, so it's a win-win. Contributing an approved drill clip earns another 5.

Yes. Post on the Community board — a friendly with the date, start/end time, region and venue, or a recruitment post with the positions and level you want. Every signed-in VBER user can see it and flag interest in-app with one tap (no contact details published), and you see who applied under "My posts".

It works on any phone, tablet or computer. Install it as a PWA; live scoring works offline and syncs when you're back online.

5-1, 6-2 and 4-2 — step through all six rotations to see the front/back row and the server each time.

Yes. Each player can log weight, body fat, vertical jump, resting heart rate, sleep and readiness — or snap/upload a photo of a scale, watch or app screen for AI to read. It's kept as a trend and feeds the AI practice planner and match analysis.

Beyond matches there's a weekly task board — post fitness / skill / nutrition quests that players accept for points on a leaderboard — and each player can run an AI fitness analysis on their trend for strengths and what to work on, so the coach sees the whole squad at a glance.

Players snap a daily photo of their meals and AI estimates the calories and protein. Once a coach approves a cut / bulk / maintain goal, the app shows each day's intake against target, and the coach can follow every player from a team nutrition overview. Estimates are approximate guidance, not medical advice.

It's a sideline chat assistant that only answers volleyball and app questions. It knows your roster, lineups and stats, can propose a rotation (and add it to the simulator in one tap) and answer tactical questions. Each question costs 2 credits; turning on web search for the latest info makes it 4.

Once a player links an account they get their own home: an FC-style attribute card computed from real match data, weekly quests, one-tap fitness and nutrition logging, and a season-long view of their own stats and progress — none of the coach's management tools.
