RefTool Free is a soccer referee tool developed by MABs Creation that can be used on Android devices. It is a free version of RefTool with ads, and requires a data connection to function. The app is designed to help referees keep track of time, record scores, and manage player misconduct.

The app comes with a timer that can be used to keep track of the game duration, including extra time. Referees can also record scores for both teams and view them at any time during the game. In addition, the app offers a card system that allows referees to issue yellow and red cards to players who commit fouls or other infractions. RefTool Free also provides a whistle sound effect that can be used to signal the start and end of the game.

However, the free version has one limitation: the coin toss feature is disabled. To access this feature and other advanced options, users can upgrade to the paid version.

Overall, RefTool Free is a useful app for soccer referees who want to keep track of important game information. While the ads may be a minor annoyance, the app is free and provides essential tools for referees to manage the game effectively.
