Optimize your training sessions

Coaches can provide instant feedback to players, helping them improve their individual and collective skills. This fosters the long-term growth and development of team members.

Advanced play calls

Train moves without having to announce them out loud? With Coachwhisperer you can insert individual sounds that you have assigned to play calls in advance.


Through this, players get more active practice times without mental interruptions and less physical standstills, which also helps to prevent injuries like muscle strains.
