THE FIRST 100% HANDS-FREE PING PONG SCOREKEEPER! PingVoice is a hands-free table tennis scorekeeper and match tracker. Keep game score by talking. Say your name and it will add a point to your score — no extra hardware or internet connection required. I built this app because I needed it. Whenever my friends and I played Ping Pong, we constantly lost track of the score and argued over whose turn it was to serve. I didn't want to break the flow of the game just to tap a phone screen. That is why I created an app that constantly listens and waits for you to say your name, instantly tracking points hands-free. This app was built with love and I hope you like it! App features: -> Hands-free voice scoring & scorekeeper -> Automatic serve tracking for singles and doubles -> Voice-controlled serve switching -> Manual tap backup to switch server instantly -> Custom team colors & player names -> 2-point or 5-point serve rotation -> Multiple table tennis themes & custom backgrounds -> Round-by-round statistics & match history -> Play standard games up to 11 or 21 points -> Voice commands to undo points -> Long-press for manual score adjustments -> Works 100% offline — no Wi-Fi required How It Works: Simply say a player's name to award a point without touching the screen. The current server is always clearly indicated with the orange ball, making it easy to follow the game. Switch the server at the start of a game using voice commands such as "serve", "switch", "alternate", or "swap", or simply tap the ball. Customize the appearance of your scoreboard with unique table and background combinations. Choose whether serves rotate every 2 or 5 points and play games up to 11 or 21 points. Made a mistake? Remove the last point by voice using commands like "undo", "remove", or "subtract", or by long-pressing a score. Track performance across rounds with detailed match statistics in the settings menu. New themes, features, and customizations are on the way!
