Poker planning should be done so that everyone displays their votes at the same time to remove anchoring effects by the more outspoken people in the team. It isnt easy to facilitate in the online world. The Planning Poker App lets the facilitator create an online planning room to which all team members connect. The facilitator decides to display all votes at the same time to avoid anchoring effects.
The poker planning app can be used offline (if everyone is in the same room) or online (by creating a planning room).
