The innovation, from equality and inclusion campaigners Kick It Out, will follow a similar app aimed at supporters, which is set to launch later this summer.
Players have used Twitter to voice complaints about racism from rival fans, and it is hoped the app will provide them with a more productive alternative by using the same medium of iPhone or Android device.
High-profile allegations of racist abuse between players have emerged in recent seasons, with both Chelsea’s John Terry and Liverpool’s Luis Suarez serving bans after being found guilty by the FA.
Complaints via the free fans’ app can be made anonymously and are automatically sent to the relevant club, the Football Association and Kick It Out. It is then up to the club and the FA to decide whether to notify police. The players’ app, which is still in development, will work along similar lines.
It comes after a Kick It Out study found that less than half of supporters know how to report incidents of racism or other discriminatory behaviour.
