A portable combination timer/calculator for basketball players and coaches that is used for indicating the elapse of selected time periods and recording the number of attempted baskets, made baskets, and shot percentages. The device includes a belt worn around a player's waist that contains a "made" basket button, and a "missed" basket button, mounted on opposite ends of the belt. Mounted centrally on the belt is an outer housing with a main on/off button, a timer, a calculator, a plurality of programmed timer buttons, and a speaker. Also mounted on the surface of the outer housing is a game select button that enables the device to be used to play various basketball related games or to be used as a recording device for "made" or "missed" baskets. The player presses the "made" or "missed" basket buttons when a shot is made or missed. Also, when the selected time period has elapsed, an audio signal is broadcast through the speaker.
