The Planning Poker Tool is an online application designed to facilitate agile estimation and planning for software development teams. It's based on the popular Planning Poker technique, which is used to estimate the complexity of tasks or user stories in a collaborative and consensus-driven way.

Here's how it typically works:

1. Team members join a virtual room on the website.
2. The product owner or facilitator presents a user story or task to be estimated.
3. Each team member is dealt a set of virtual cards with different values (e.g., 0, 1, 2, 3, 5, 8, 13, etc.).
4. Team members anonymously select a card that represents their estimate of the task's complexity.
5. The cards are revealed simultaneously, and the team discusses any discrepancies in the estimates.
6. The team repeats the process until a consensus is reached on the estimate.

The Planning Poker Tool provides a digital platform for teams to conduct these estimation sessions remotely, making it easier to collaborate and estimate tasks efficiently. It's a useful tool for agile teams, scrum masters, and product owners to facilitate effective planning and estimation.
