PoolTool is a free iPhone app developed by pooltool.io LLC. It falls under the Business & Productivity category, specifically in the Finance subcategory. With PoolTool, you can explore the Cardano blockchain and track your rewards.

The app allows you to browse the pools of the Cardano network and mark your favorite stake pools. You will receive notifications when these pools change fees, pledge, create blocks, or become saturated. PoolTool is designed to be accessible on the go, providing you with a meaningful filter and sort for the hundreds of registered pools.

In addition to tracking rewards, PoolTool offers detailed information and historical data about all the pools. You can view their websites, descriptions, pledged ADA, fees, block production, and controlled stake.

PoolTool welcomes feedback and feature requests, which can be provided through Twitter, Telegram, or their website.

Cardano, the blockchain supported by PoolTool, is the home of the ADA cryptocurrency. ADA can be used to send and receive digital funds securely through the use of cryptography, ensuring fast and direct transfers.
